4-10. Voltage Sensing Lead Connections
Unit is factory set for constant volt-
age (CV) welding. To set unit for
constant current (CC) welding,
proceed as follows:
1 Terminal Strip 2T
2 Strain 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.
4 Motor Speed Control Board
PC1
5 Jumper Plug
6 Receptacle 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.
