Instruction Manual1(this document)● For marking metals primarily composed of iron, (iron, steel, stainless steel.)

Oxide coated steel can not be marked due to poor surface conductance.
which are non-conductive (plastic, wood, etc.) can not be marked.

● For large items, if the ground and electrode distance is too great, theconductance may be poor and it can not be marked.

● Dirt, oil, grease, and rust will interfere with electrode conductance andprevent marking. Surface should be thoroughly cleaned before marking.

● Make sure all cable mounting screws (Output terminals, Ground Plate, andMarking Pencil,) are securely tightened.

● The Pencil Tip is hot. Wear heat-resistant gloves, and do not touch thePencil Tip. With use, the Cables and Ground Plate will also become hot This is normal operation.
● With long exposure, warm temperatures can cause burns - Use caution.
● Do not block the cooling fan or ventilation holes on Control Box.
● Pencil Tip will become dull with use. Sharpen with file as required.
● Keep away from children at all times.
● Do not use or store in hot or humid location.
● Do not crush or pull on Cables.

1. Make sure that the power switch is turn OFF before plugging in the power cord.
2. Connect the Ground Plate Terminal to the Ground Cable.
3. Connect the Marking Pencil (with tip) to the Marking Pencil Cable.
4. Connect the Ground Cable to one Output Terminal, and connect the Marking Pencil Cable to theother Output Terminal. (As there is no polarity, the cables can be connected to either terminal.)
5. Place the workpiece on the Ground Plate and make sure the there is good contact to the plate. If
workpiece does not have good contact to the Ground Plate, the workpiece may form burn marks
at the contact point.
6. Make sure the Pencil Tip is not touching the workpiece before turning on the Power Switch.
7. Adjust the Voltage Control Knob. Use lower setting for thin

workpiece, and higher setting for thick. (See diagram at right.)
eor(Voltage also controls amount of marking on workpiece.)
8. When Pencil Tip makes contact with the workpiece, it will begin tomark. Hold the Marking Pencil and write the desired characters as
you would a normal pencil.

Thank you for purchasing the EP-A3 Electric Marking Pencil.
Please read this manual thoroughly before use to insure proper operation and long service.

Control Box

Thin Marking Pencil Cable● The Thin Pencil Cable can be used in place of the Standard Cable; because it is more flexible,

fine marking is easier using the thin cable.

WARNINGThe Thin Cable will heat up more than the Standard Cable. Use only when marking is for shortperiods, or workpiece is thin and excessive heat is not created. Please select the proper Cable
according to conditions.
