5-8. Connecting To Weld Output Terminals

Stick and TIG Welding

For Stick and TIG welding Direct Current Elec- trode Positive (DCEP), connect electrode holder cable to Positive (+) terminal 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 or op- tional Polarity/AC switch, connect electrode holder cable to Electrode (+) terminal on left and work cable to Work (−) terminal on right.

MIG and FCAW Welding

For MIG and FCAW welding Direct Current Electrode Positive (DCEP) on CC/CV models, connect wire feeder cable to Positive (+) termi- nal on left and work cable to Negative (−) ter- minal on right. Use Process/Contactor switch to select type of weld output (see Section 7-3).

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

If equipped with optional Polarity switch or op- tional Polarity/AC switch, connect wire feeder cable to Electrode (+) terminal on left and work cable to Work (−) terminal on right.
