Work Cables

For MIG and FCAW welding Direct Current

Electrode Positive (DCEP), connect work

cables to Negative (−) terminals and wire

feeder cables to CV terminals.

For MIG and FCAW Direct Current Elec-

trode Negative (DCEN), connect work

cables to CV terminals and wire feeder

cables to Negative (−) terminals.

If unit has the Polarity switch option, con-

nect work cables to Work receptacles and

wire feeder cables to CV receptacles.
