Unit is factory set for constant volt- age (CV) welding. To set unit for constant current (CC) welding, proceed as follows:
1Terminal Strip 2T
2Strain Relief
Loosen screws of strain relief.
3 Voltage Sensing Lead
Route ring terminal end of lead through strain relief, and connect ring terminal to terminal A of terminal strip 2T. Tighten screws on strain relief.
4Motor Speed Control Board PC1
5Jumper Plug
6Receptacle RC5
For constant voltage (CV) welding, place jumper plug in INT. position. Do not connect voltage sensing lead clamp to workpiece.
For constant current (CC) welding, place plug in EXT. position. Connect clamp end of voltage sensing lead to workpiece.
Reinstall right side panel.
