(1) Plug the line cord connected to the back of the Power Unit into a 110/120
VAC outlet only. Converters are available on request for 220/240 VAC.
(2) Plug the BLACK cord into the BLACK (MARK) receptacle: the opposite
end of the cord into the Bench Fixture.
(3) Plug the RED Cord into the RED (GROUND) receptacle; slide the alligator
clip off the opposite end and slide on the Hand Ground.
(4) Set the AC-DC Switch on AC for most metals and DC for Aluminum and Black
Oxide. AC produces a black mark; DC produces a frosted or clear mark.
(5) Set the Normal/Deep-Etch Switch on NORMAL.
(6) Set the Rheostat on No.5. Note: If the mark is blurred, turn the
Rheostat to a lower position.
(7) Place a clean Wick Pad on the graphite block in the Bench Fixture
(green side down) and secure the Wick with a Retainer Ring.
(8) Saturate the Wick Pad with the proper Electrolyte. Select the
proper Electrolyte from the chart on page 5.
(9) Place Stencil with the legend reading REVERSED over Wick Pad
and secure a second Retainer Ring. (Stencil may also be secured
by a Locating Plate, which is milled to fit the part).*
(10) Set the ON-OFF Switch to ON position.
(11) Place part to be marked in fixture and ground by touching part
with either the Hand Ground, Finger Ground, or with the alligator
clip. NOTE: Etching may be accomplished by rolling the part
across the stencil with Hand Ground or by placing the part in the
Locating Plate and grounding with the Hand Ground or Finger
Ground.
(12) After marking each part, thoroughly clean the parts with APC
Cleaner by wetting a clean shop cloth with the Cleaner and
rubbing the part, making sure that none of the Electrolyte is left
on the part, or by immersing the part in a small open container
filled with APC Cleaner.
(13) After cleaning the parts thoroughly, dry them with a clean dry cloth.
(14) After marking is completed, turn the ON-OFF switch to OFF.
Unplug the BLACK and RED cords from their receptacles.
(15) Remove the Wick Pad from the graphite block and wash
thoroughly with water. Wick Pads are reusable if they wash out
reasonably clean.
(16) With water, thoroughly rinse the Bench Fixture, Retainer Rings, Hand Ground and any other material that came in
contact with the Electrolyte.
(17) Dry the above mentioned items with a clean, dry cloth.
(18) Discard all used Electrolyte and Cleaner. NOTE: Never pour used Electrolyte and Cleaner back into the bottles as
the oxidation from the parts will contaminate the fresh solutions.
(19) After all these steps have been followed, your equipment and supplies will be ready for use the next time.
