2Negative (–) Weld Output Terminal

For Stick and TIG welding Direct Current Electrode Positive (DCEP), connect electrode holder cable to Positive (+) ter- minal on left and work cable to Negative

(–) terminal on right.

For Direct Current Electrode Negative (DCEN), reverse cable connections.

If equipped with optional polarity switch, connect electrode holder cable to Elec- trode terminal on left and work cable to Work terminal on right.

For MIG and FCAW welding Direct Cur- rent Electrode Positive (DCEP) on CC/ CV models, connect wire feeder cable to Positive (+) terminal on left and work cable to Negative (–) terminal on right. Use Process/Contactor switch to select type of weld output (see Section 6-3).

For Direct Current Electrode Negative (DCEN), reverse cable connections.

If equipped with optional polarity switch, connect wire feeder cable to Electrode terminal on left and work cable to Work terminal on right.
