                                                             SET-UP AND OPERATION

                                              The Model MS-400-cc Power Unit is designed to operate
                                              manually, semi-automatically or automatically.
                                              Follow the set-up and operating instructions given for
                                              your application.
  operate                                     MANUAL SET-UP
  operate                                     A) Plug your unit into a 110-120 Volt (AC) outlet only.

                                              B) In the manual mode only two (2) wires are required.
                                                 Plug the Black wire into the “Monode” jack on the front
                                                 of the unit (Figure 4, Illustration 3-A) and the Red wire
                                                 into the “Ground” jack (figure 6, Illustration 3-A).
      ILLUSTRATION 1-A                        C) Clip the ground clip attached to the Red wire directly to
                                                 the part being marked to a grounding plate or fixture.

                                              D) Plug the opposite end of the Black wire into the end of
                                                 the H-100 Holder (Hand Marker – Handle)

                                              E) Insert the marker (Black Carbon Head) into the H-100
                                                 Holder. Make sure the two are properly aligned and
                                                 gently press the handle securely onto the tapered carbon
                                                 nipple attached to the head. The friction fit between
                                                 these parts requires very little force.

                                              F) Attach a Deep Etch Pad or Monopad to the marking head
                                                 with the “O” ring clip provided. Fold the pad evenly
                                                 over the marker with the blue fabric side of the pad
                                                 against the Carbon Head. Slide the “O” ring over the
                                                 head and monopad until the “O” ring snaps into the
                                                 machined grooves in the side of the head securing the
                                                 monopad in place.

  A) All four (4) adjustment dials (Figs. 1 & 9) are inactive during manual operation. Use only the
     following buttons: “ON-OFF” (Red), “AC-DC” (Blue), “POWER SELECTION A thru F (White)
     Make sure the “TIMERS ON” and “REPEAT” buttons are in the up (off) position.
     (See Figs. 2,3,5 and 8, illustration 3-A).
     Turn the power unit on. Choose the proper current setting. AC produces a black etch.
     DC produces a white etch and is also used when deeper etching is required.
     A white etch may be more desirable when marking various metals such as black oxide or brilliant
     highly reflective material finishes such as Polished Stainless Steel or Chrome. This will produce
     a matte finish etch which contrast with the bright reflective finish making it more easily visible.

                                                  Page 2
 B) The Model Ms-400-cc Power Unit is equipped with six power settings: A= 5 Volts, B= 8Volts,
    C= 11 Volts, D=14 Volts, E= 17 Volts, F=20 Volts. Depress any one of the white power setting
    buttons to select the desired voltage. Always use the lowest power setting possible to prolong
    your stencil life. The more current passing through the stencil, the more heat is generated.
    The more heat generated the more damage is potentially being bone to your stencil. This applies
    to all stencil types including Long Life Fabric Stencils, Standard Paper Stencils and High
    Resolution Thermal Printed Paper Stencil product.

 C) Apply one of Millennium Signatures Marking Systems formulated electrolytes to the monopad.

 D) You are now ready to mark your part. Position your stencil on the part. Using only very gentle
    pressure apply the marking head by pressing the damp monopad against the stencil making sure to
    cover the exact areas on the stencil where the image appears. Results should happen immediately
    and contact with the part should not exceed 2-3 seconds for conventional surface etching

 E) Removing the hand marker from the part. Then remove the stencil from the surface of the part to
    reveal your etched results. Due to the fact that the electrolyte is sodium based and the residue left
    behind could continue to cause some surface oxidization, it is highly recommended that you use a
    clean cloth or sponge to wipe the surface of the part effected by the marking with a neutralizer that
    is designed to neutralize any traces of sodium remaining. It is recommended that our Standard
    Neutralizer Formula or our Heavy Duty Concentrated X4R-900 Neutralizer is used for this

 F) After the part is dry, our MS-RPO (Rust Protective Oil) product can be applied to the area for
    additional protection is desired.


 A) Plug your power unit into a 110V AC power outlet.

 B) Connect the four wire cord set to the corresponding jacks on the power unit and the marking
    machine, for example: black to black, yellow to yellow, and green to green.

     The red lead is the ground. Be sure the ground lead is properly grounded to the part or fixture in
     semi-automatic marking operations.

     Please note: on applications using marking from the bottom up or simultaneous top and bottom
     marking, request set-up information from your sales representative.

 C) Plug the footswitch into the back of your power unit.

 D) Place the appropriate monopad on the marking head and attach the insert stencil, cap
    stencil, or flat stencil as required.

 E) Place the long tube from the #152 electrolyte pump in the open bottle of electrolyte.
    Prime the pump by rotating quickly clockwise. The pump is adjusted by the small set
    screw on the stop below the lever.

                                               Page 3

  A) Depress the red “ON” button.

  B) Choose the desired current by selecting the blue “AC/DC” button. When the
     button is in the up position it is set for AC, when depressed it is set for DC.

                                                    ILLUSTRATION 3-A

  C) The button identified as “REPEAT CYCLE” should be in the up position. This
     allows the footswitch to start the marking cycle.

  D)   Set the cycle time by rotating the dials under the heading “ACCESSORY
       CYCLE TIME”. (See Fig. 9) To control the amount of time the marking head
       spends in contact with the part being marked (dwell time), the dial marked “ON”
       is rotated clockwise to the desired setting. Most dark marking applications
       require a setting of one to three seconds.

       The dial marked “OFF” is not used when using a footswitch to start the marking
       cycle. The “REPEAT CYCLE” button is up.

  E) Set the current cycle time with the timers marked “MARKING CURRENT

                                                Page 4
NOTE: Most etching operators do not use the “MARKING CURRENT CYCLE
       TIMERS”. They are activated by pushing the “TIMERS ON” button.
       (Fig. 5)

       The dial marked “ON” controls the length of time the marking current is
       delivered to the marking head. The “OFF” timer controls the length of time the
       current flow is interrupted. These timers continue to alternate timing until the
       total cycle time, the time set by the “ON” timer, under “ACCESSORY CYCLE
       TIME” expires. For example: if the total time controlled by the “on” timer
       under “ACCESSORY CYCLE TIME” is 8 seconds, and the timers under
       “MARKING CURRENT CYCLE TIME” are “OFF” 1 second and “ON” 2
       seconds, the timers would sequence OFF, ON, OFF, ON, OFF and then the head
       would retract.

       These timers are used for applications that require a long marking time. A long
       marking period builds up heat that breaks down the stencil. These timers pulse
       the current to the marking head. This prolongs the stencil life and reduces the
       total marking time needed.

       These timers are also helpful in marking contour parts. The “OFF” timer is first
       to time out. This allows time for the marking head to descend and seat the
       stencil on the part before the current is supplied. This improves the quality of
       marks on contoured surfaces.

   F) To activate a single machine marking cycle, depress the footswitch.


  Set-up for automatic marking is the same as for semi-automatic marking. Refer to
  the instructions previously given.


  Set-up and control functions are the same as semi-automatic operations except the
  footswitch is not used to activate each marking cycle.

  Set the “OFF” time under “ACCESSORY CYCLE TIME” to the amount of time r
  required between marking cycles, for example the amount of time an operator may
  need to load and unload the part fixture.

  Push the “REPEAT CYCLE” button (Fig. 3) Use the footswitch to start the
  automatic marking equipment.


  It is important to keep your unit free of oxidation, and salt build-up. This will
  insure years of dependable, trouble free operation.

                                               Page 5
A) Keep the cord ends, alligator plug, marking heads and grounds clean. If
   corrosion appears, use a light abrasive, such as an emery cloth, to clean it off.

B) To prevent corrosion build-up, separate the marking head from the H-100 holder
   at the end of the day. Remove the top plate of the MS-1220 or MS-2045 bench
   fixture when it is not in use. Following these simple steps will keep the two
   surfaces from fusing together, insuring good electrical contact. This will allow
   quick change over for between runs.

B) Millennium Signatures stencils and pads are designed to be used over and over again.
   Simply rinse them under cold water and place them on some toweling to dry.
   They are ready for use whenever you are.

                          MARKING APPLICATIONS

        A) To avoid short circuits (See illustration 1-A), do not cross the leads, or make
           contact between the marker and the grounded surface when both surfaces
           are bare.

     1) Plug the black wire into the black jack of the bench fixture.

        2) Remove the top plate (carbon) from the fixture.

        3) Pour the recommended “pH” balanced electrolyte into the well.

        4) Replace the top plate.

        5) Place a monopad (white side out) on the top plate, and secure it
           with the enclosed “O” ring. Make certain that the sides of the pad are
           tucked down inside the well. This will insure that your pad will draw the
           fluid without operator assistance. Use either a MS-1220-3, MS-1220DE,
           MS-2045-3, or MS-2045DE monopads for best results.

        6) Place the stencil over the pad with the reading face down, as if to read the
           information from the bottom of the fixture. Slide the “O” ring over the
           stencil pad and top plate until it snaps into the machined groove.

        7) Connect the hand ground (flat bottom or knife edge) to the ground jack of
           your power unit.

        8) Place the substrate (surface to be marked) on the stencil in front of the
           reading. Place the hand ground on the substrate, and roll the substrate over
           the reading, using moderate pressure.

        9) Use Millennium Signatures X4R Series “pH” balanced neutralizer to neutralize
           any area of the substrate that has come into contact with the electrolyte.

        10) For added protection, apply Millennium Signatures Rust Preventative Oil
            (RPO). It is always a good practice to apply oil to a clean dry surface.

              LEADERS IN QUALITY

                    Electro-Chemical Etching
 Electro-Chemical Etching does not cause distortion, sharp indentations, or unbalance in delicate parts.
This process is widely accepted as a modern and economical way to mark on conductive metal surfaces.
           Manufacturers who produce nearly anything from fine cutlery to saw blades and
           Aerospace Components prefer this method of permanently identifying their parts.

  Electro-Chemical Etching is most applicable where hardened, thin and delicate, or already assembled
parts must be marked permanently. There is no external force required to make any indentation or mark.
 Simple, fast & safe, The Electro-Chemical Etching Process is actually the reverse of electro-plating. A
  low pulsating voltage, low amperage current is passed through the open aperture of a paper or fabric
 stencil . The polarity is reversed from that used for electro-plating. A permanent surface etch 0.0001”
                              deep is easily made in less than one (1) second.

                                            DEEP ETCHING
    In some industries such as Automotive or Aerospace, specifications call for DEEP ETCHING in
 applications where the marked surface of the part may experience some wear or the mark must be deep
               enough into the part to allow it to be clearly read once painted or anodized.
Millennium Signatures Marking Systems produces heavy duty Power Units that are equipped with timers
and current control features such as our Electronic Pulse Control or EPC feature combined with a higher
output allowing marking results of potentially up to 0.0010” or 0.0012” deep depending on the material
                                           and techniques used.

  On most metals you have the control to produce a clean professional looking mark in one of three (3)
                     possible colours or contrasts, Black, White (Clear) or Grey.

                                         SAFE AND EASY TO USE
The Electro-Chemical Etching Process is so easy to use that personnel need no special skills or training to
 use effectively. It is so fast that most permanent surface markings are made in less than one (1) second.
                         The low currents used are harmless so it is absolutely safe.

  Any conductive metal part especially those, which are hardened or may not be subjected to additional
         stresses or deformation resulting from stamping, vibro pens or electric arc marking.

                                 IDEAL APPLICATIONS INCLUDE
         Taps & Dies                     Nuclear Components                       Turbine Blades

Solid State Circuitry and modern design provides long lasting service using a minimal amount of energy.
Our advanced technology is just one reason why Millennium Signatures Marking Systems is a World
Wide Leader in Electro-Chemical Etching systems and supplies.

AC and DC output with 6-position switch.
Settings A through F regulate the marking voltage, ranging
from 5 volts progressively through 8 volts, 11volts, 14 volts,
17 volts and ultimately 20 volts on the F setting.
Electrolytic Stencil Cleaning Current is available through the
yellow output jack. When connected to a cleaning tray it serves
as an effective method of removing a build up of oxide out of
the open aperture of fabric stencils as to improve marking
quality and extend stencil life. Additionally, if the Black
(Monode) lead is moved to the Yellow output jack a high
output side of the transformer is activated that will provide
DEEP ETCH results to approx .003” depth below the surface.

                                           Ideal for Grid Marking or DEEP ETCH applications
                                           AC and DC output with a 6-position selector switch.
                                           Settings A through F regulate the marking voltage, ranging
                                           from 5 volts progressively through 8 volts, 11 volts, 14 volts, 17
                                           volts and ultimately 20 volts on the F setting when on the LOW
                                           setting. This heavy duty unit can be switch to a HIGH range
                                           that doubles the voltages on all settings to a maximum or 40
                                           volts. This unit is best suited for manual production marking
                                           where more power is needed for extreme depth. This unit will
                                           accommodate surface marking requirements from 0.0001” to
                                           more aggressive marking of 0.006” below the surface.

 AC and DC output with 6-position switch. Voltage ranging
 from 5 volts progressively through 8 volts, 11 volts,
 14 volts, 17 volts and ultimately 20 volts. The pulsing
 current generated by this unit results in a cleaner extraction
 of material and deeper results. The EPC feature (Electronic
 Pulse Control) and the cycle timers have proven effective
 for consistent depth and quality from part to part and greatly
 extends the life of Fabric Stencils. This unit is equipped
 with the necessary circuitry to support the AM-10-A and
 AM-30-T semi and fully automated etching systems.

All of the Electrolyte Solutions manufactured by Millennium Signatures Marking Systems are completely
safe to use. The solutions are all based on a mild sodium solution and do not contain harsh chemical or
anything acidic or corrosive. All formulations have continuously updated MSDS sheets available.

While the solutions are said to be non-corrosive as they can be safely handled and not pose respiratory
threat or danger when in contact with the skin, there is the potential that the surface area of your part in
close proximity to the location of the mark could develop a light oxidization. This directly due to the
sodium content of the electrolyte and this oxidization affect can be nearly undetectable or more advanced
based on environmental conditions. This side effect of the process can be completely prevented by the
proper use of one of our Neutralizer products that when properly used will instantly neutralize the sodium
in any traces of the solution that may be left on the surface of the part after marking. Though who are
new to the process and/or those who have failed to properly neutralize their parts after marking may find
that this side affect is more noticeable during times of the year when higher levels of humidity are present.

For more information on Neutralizers and Rust Protective Solutions, please see the
NEUTRALIZERS & RUST PROTECTIVE OILS section to follow within this information kit.

Laboratory Tested & Certified
If required, we can not only produce your electrolyte to meet your specification in most cases we
routinely provide the service of having batches of a specific formula analyzed and certified at an
independent Laboratory to confirm that the solutions meet industries specific needs.
To have this service provided additional costs would apply.

Our PAPER STENCIL product is specially designed and manufactured to allow customers to quickly and
easily create their own temporary stencils on demand, ideal for applications with variable information.
Stencil Paper can be used to create etching stencils with the use of either a typical impact style typewriter
or with our Model 9300 Series Stencil Imprinter. The Stencil Imprinter is a computer controller Dot
Matrix device very similar in design to a conventional Dot Matrix Printer commonly used for regular
paper and identical in terms of operation. The Imprinter serves as a slave to your computer and can print
text and images from pretty much any application software including Microsoft Word, Corel Draw and/or
AutoCAD to name a few.

The Stencil Imprinter is outfitted with a custom Heavy Duty 24-Pin Print Head designed to offer the ideal
impression on both the standard and DEEP ETCH Stencil Paper products. The Imprinter is also outfitted
with a slightly different carriage assembly and a special ribbon assembly. The ribbon assembly is the
only consumable, periodically requiring replacement much like a conventional printer over time aside
from the Stencil Paper itself.

The Stencil Paper is available in three different styles.

   A) Heavy Duty (DEEP ETCH) Paper available in two widths 2-1/2” wide and 3-3/4” wide and both
      are available in 100’ and 600’ rolls.
      ♦P/N D-I-27 Box of 100 sheets of 2-1/2” wide X 7” long pre-cut sheets (for typewriters)
      ♦P/N D-I-B 2600 100’ Roll of 2-1/2” wide Stencil Paper
      ♦P/N D-I-B 3600 100’ Roll of 3-3/4” wide Stencil Paper

   B) Standard grade (Light Blue) Tractor-Feed Stencil Paper also available in two widths, 2-1/2” wide
      and 3-3/4” wide and both are available in 100’ and 600’ rolls. This paper is outfitted with the
      holes located down each side of the paper to allow for positive locating and feeding of the paper
      when using the Model 9300 Series Stencil Imprinter.
     ♦P/N D-I-2600-TF 100’ Roll of 2-1/2” wide standard grade Stencil Paper with Tractor-Feed
     ♦P/N D-I-3600-TF 100’ Roll of 3-3/4” wide standard grade Stencil Paper with Tractor-Feed

   C) Heavy Duty (DEEP ETCH) Tractor-Feed Stencil Paper is also available in the same two widths,
      2-1/2” wide and 3-3/4” wide and both are also available in the 100’ and 600’ rolls. This paper is
      outfitted with the holes located down each side of the paper to allow for positive locating and
      feeding of the paper when using the Model 9300 Series Stencil Imprinter.
      ♦P/N HD-2600-TF 100’ Roll of 2-1/2” wide Heavy Duty Stencil Paper with Tractor-Feed
      ♦P/N HD-3600-TF 100’ Roll of 3-3/4” wide Heavy Duty Stencil Paper with Tractor-Feed

                                                      Page 5
When an impression is made on the Stencil Paper using either a Typewriter or the Model 9300 Series
Stencil Imprinter, a stencil could last anywhere from 3 or 4 markings to potentially around 20+ markings
if applying a basic surface etch and it is all depending on the technique used, environment and handling of
the stencil. When DEEP ETCHING, each image is usually only good for one marking.

                                                Tractor Feed Stencil Paper is available in two widths 2-1/2”
                                                wide and 3-3/4” wide. The dimensions mentioned are the
                                                actual usable (blue) portion of the paper and does not
                                                include the white tractor feed portion.

                                                Stencil Paper should be stored in a cool dry and dark
                                                location. Avoid leaving the paper in bright ultraviolet light
                                                for any long periods of time if not necessary.

        Model 9300 Series Stencil Imprinter

The (NEW) Model 9300 Series Stencil Imprinter is manufactured by EPSON a world leader in the
manufacture of Dot Matrix Printers. This HEAVY DUTY Printer has been equipped with a Custom
Modified Print Head and Ribbon Assembly giving it the ability to impress high quality images on our Die
Impression Stencil Paper Products (above). This Stencil Imprinter connects to any PC via Parallel Port
Connection and operates as a slave to any application software. This NEW design operates quickly and
quietly allowing high quality stencils to be created on demand.
The computer driven Model 9300 Series Stencil Imprinter offers many features that would otherwise be
impossible using a standard typewriter for creating your stencils. While a standard typewriter can be very
effective for the most basic applications, you are limited to text sizes, straight-line imprinting and no
ability to imprint graphics among others.

                                      work in combination with the customized properties of the Print
                                      Head and Carriage assembly to provide a high quality imprint that
                                      is ideal for the Chemical Etching Process. Ribbon replacement is
                                      mechanically no different from a standard Dot Matrix Printer.
                                      No tools required

Our Long Life FABRIC STENCIL product is custom manufactured to suit your marking applications by
Millennium Signatures Marking Systems. The Long Life Fabric Stencils are made using a unique
photographic process that produces the required stencil artwork onto a very durable almost plastic like
fabric sheet. The artwork capabilities with Fabric Stencils are much more advanced than what can be
produced using the Paper Stencil product.

Customers can supply their own high quality digital artwork or they can have artwork made to suit by our
in-house Graphic Artwork Department. The artwork can consist of pretty much anything from a Logo to
a Schematic Diagram. The quality of the final image will be far superior to what could be achieved with a
Paper Stencil due to the sharpness and fine details of the image that can be maintained when processing
the stencils using a photographic process.

Long Life FABRIC STENCILS are best suited for applications that require the marking to be
exceptionally cosmetic or attractive to the eye and/or in applications where the same information is going
to be used over and over again for large quantity of pieces or different products on an ongoing basis.

Millennium Signatures is capable of producing these sheets made to order in pretty much any
combination of sizes up to a maximum of 10” X 10”. You can produce thousands of conventional surface
markings (0.0001” – 0.001”) with each image on the sheet (regardless of sheet size). Fabric Stencils are
NOT recommended for Deep Etch applications as the life of the stencil will be dramatically reduced due
to the amount of current (Voltage) that is required to pass through the stencil and the heat that is generated
as a direct result.
                                                   Page 7
Fabric Stencils Cont’d
The way that the Fabric Stencil are produced allows the stencils themselves to be priced based on sheet
size as opposed to the number of images on each sheet. Therefore if you purchase a Fabric Stencil sheet
that is 2-1/2” wide X 7’ long and you have an image that can fit comfortably on that sheet three (3) times
down the center of the sheet (as in example below), you can easily achieve thousands of high quality
surface etch impressions per image (Example A) . In some cases it might be more beneficial if you require
a few different image sizes to suit various different sized parts, you could purchase a single sheet with the
artwork requirement located as many times as possible on that sheet in the different sizes that you require.
In either case the price would remain the same as the sheet size has remained consistent. (Example B)
The number of images on the sheet is determined by the size of each image and adequate space left
around those images. There has to be enough insulating fabric around each image to ensure that the
Monopad and Carbon Head Assembly does not come in direct contact with the surface of the part or a
black marking (smug or smear) could be etched permanently on the part around the image itself.
To prevent this there has to be a reasonable amount of insulating fabric around each image somewhat
limiting the number of images that can be produced on each sheet size

Example A:

                                                                           Long Life Fabric Stencils are

                                Positive Feed Electrolyte Pump – Delivers an exact amount of
                                electrolyte directly to the marking head and only while marking as
                                the pump is activated by the motion of the AM-10-A so that when
                                the system stops processing parts, the feed of electrolyte to the head
                                stops also. No spillage or flooding due to operator neglect with this
                                feature. To change electrolytes simply remove drawtube from old

AM-10-A Semi Automatic Etching System – The Models
MS-400-CC or MS-510-DE Power Unit must be used in
conjunction with the AM-10-A. These units when properly
set will automatically cycle the AM-10-A so that all the
operator has to do is load and unload the parts. The system
can also be activated manually via foot pedal. Cycle time on
this unit is approximately 1200 parts per hour. This system is
also exceptionally effective at ensuring that the mark quality
to consistent from one part to the next as all aspects of the
process are controlled. Long Life Fabric Cap Stencils are
most effective with this system.

Foot Pedal – The Foot Pedal serves as a very useful tool in both
manual and automated applications. The foot pedal allows the
operator to work at his or her own pace on the AM-10-A semi-
automatic unit by using the foot pedal to activate the cycle. In
manual applications the foot switch also makes providing power
to the part simple when trying to hold and precision mark a part.
Excellent feature when working with a ground plate, in most
cases preventing direct contact with the ground from occurring.

The Electro-Chemical Etching Process is very safe and simple to use. Despite that a very basic Black or
White surface etch of 0.0001” to 0.001” depth can pretty much be done by anyone and achieve the best
results, if your needs require a deeper etch ranging right up to (potentially) as deep as 0.012” below the
surface is pretty much an identical process however the proper techniques can greatly improve the clarity
and depth of your results as well as time and efficiency.

With over 30 years of experience manufacturing the Electro-Chemical Etching process we have worked
with pretty much every different material and with specifications from all industries. By following the
recommendations listed below or contacting our sales and/or technical staff we will definitely help you
improve your marking results.

Using the AC Current Setting will provide you with what is considered to be a BLACK mark. These
results are dependent on the type of material being marked and that the proper electrolyte solution is being
used. When operating any of the Millennium Signatures Power Units on the AC current setting, you are in
effect extracting material from the surface and re-depositing a black oxide leaving the product with a
permanent, stressless mark that will reflect exactly the image of your Paper or Fabric stencil.
While the AC current setting is usually most successful in getting the cosmetic results required for most
applications given the contrast of the black mark, the AC setting does not provide as an aggressive
reaction with the electrolyte and so therefore it is difficult to achieve greater marking depths on this
setting. While the DC current setting creates a much more aggressive reaction with the electrolyte
offering greater marking depth, it does not produce an oxide and therefore can be used to achieve any
one of the following four results. (1) If depth is not necessarily required but you are marking a bright and
highly reflective material such as a polished stainless steel, the DC setting will actually give you what is
considered to be a CLEAR mark as it does not have colour but it results in a matte finish etch against the
high polished surface which provides a more easily readable result. In such a case it might seem
reasonable to mark such a material with the AC setting providing a black mark, however if the surface is
highly reflective the black image although very much there and permanent tends to get lost in the
reflection and is not easily visible. (2) If greater marking depth is required and the marking is going be
subject to a coating, paint or anodizing then the best results to achieve the depth effectively would be on
the DC setting. (3) In the event that depth is desired but you also want to have the black mark for the
purpose or greater contrast and better visibility, you should use the DC current setting to etch down to the
desired depth and then without disturbing the registration of the stencil and the part switch over to the AC
current setting for an additional few seconds and you will end up filling the cavity with oxide resulting in
a deep and highly visible mark. (4) In a case where the parts to be marked are Black Oxide coated, the
black mark achieved on the AC setting would be mostly undetectable and so switching to the DC setting
and using the proper electrolyte (X4R-415 in most cases) will give you the appearance of a WHITE mark
against the black surface of the part.

One of the key factors involved when NOT achieving the desired marking depth or doing so with very
poor efficiency or mark quality is the breakdown or deterioration of your Monopads and or Paper/Fabric
Stencils. The most likely cause of this deterioration is Heat.

                                                 Page 13
The most effective technique allowing you to minimize the heat that is produced while deep etching is to
either hold your paper stencil firmly in place or for really deep etch applications it is even suggested that
you tape the stencil securely in the proper location and gently rock the carbon head assembly with the
monopad attached lifting the head assembly a centimeter or two from the part every few seconds allowing
the heat being generated by the reaction to dissipate. There is no need to press the marking head assembly
against the part with any force. The marking head assembly with a monopad properly dampened with the
proper electrolyte solution just needs to make contact with the surface of the part through the stencil and
any additional or aggressive force may only disturb the registration of the stencil or deplete the amount of
electrolyte solution being held in suspension by the monopad.

It is also strongly suggested that for really deep etching applications considered to be where achieving
marking depths of 0.005” below the surface or deeper two monopads on located directly on top of the
other and secured to the Carbon Head with an “O” Ring Clip will provide better results. The two pads
will allow more electrolyte to be held in suspension and maintain less heat. If the monopads get too dry,
the amount of heat will increase and not only produce poor marking results, but will deteriorate the
Paper/Fabric Stencil and Monopads quickly.

 After marking several parts the operator will start to notice the discolouration of the monopads. The pads
trap micro particles of metal that have been removed in the process as well as some oxide that is produced
at the same time. The pads will become flat and lose their absorbency. Once these pad(s) become
relatively soiled or no longer hold much solution, they should be removed and washed out by hand.
Washing these Monopads is simple and only takes a few seconds. Simply hold the pads under some
warm running water at the sink and using some common liquid soap work to lather with your fingers for a
few minutes, then rinse the pads thoroughly and allow them to dry completely before re-using. When you
get to the point where the absorbency of the pad can not be restored with washing and the pad is heavily
soiled with metal particles and will not clean up at all, it is time to discard the pad(s) and start again with
fresh supplies.
 Monopads are made with a very pure material that contains no oils or waxes etc. It is important if you
wish to achieve quality results that you use the proper Monopads as opposed to other materials such as
regular felt to hold transfer the electrolyte as most other materials do contain colourings, waxes, oils etc.,
which have proven break down the reaction process and produce poor quality results.


Paper Stencils are considered to be disposable and require no special care, however a little tip that will
help with your marking results especially on standard surface etching applications. Do a short test etch on
a sample piece of metal using the DC current setting on a low to medium voltage output to allow the
initial reaction and voltage passing through the open aperture of the stencil, in effect cleaning out the
aperture and putting the stencil in excellent condition to leave perfect mark the second time on the good

Fabric Stencils are designed to produce many hundreds and often thousands of quality markings.
There are some things that can be done to properly maintain the stencils. Always make sure that the
marking surface is free of solvents or other harsh chemicals that may damage the stencil. Watch to make
sure that your part does not have any burrs or metals cutting that might put even a tiny slice in the sheet
stencil material. After marking it is a good idea to rinse the stencil under a tap and wipe clean on both
sides with a soft non-abrasive cloth and allow to dry. In between parts while marking periodically
inspect the stencil to ensure that the open aperture (image) portion of the stencil is still relatively white or
semi-transparent and not turning black as the aperture fills with excess oxide created in the process.
                                                   Page 14
Stencil Cleaning Trays are quick and easy way to maintain your stencils. The tray plugs into the
CLEANER jack on the front of all power units and it is a shallow tray that is to be filled with the marking
electrolyte to create a bath. Using reverse polarity the oxide and contamination in the stencil is drawn out
of the stencil and trapped in a Cleaning Tray Pad on the bottom of the tray. This is the very best way to
care for your stencil and also requires the least amount of effort and can quickly be done in between parts
throughout a marking session.

Stencil Repair should it be required may be possible using a standard nail polish as is available in any
drug store. In the event that you should manage to get a small perforation in the stencil or a scratch,
crease or some similar such damage should break down the insulating ability of the stencil and markings
that reflect that damage show through on your part, the easiest thing to do would be to cover that area
with a thin even coating of nail polish.
