Stick And TIG Welding

For Stick welding Direct Current Electrode Positive (DCEP), connect electrode hold- er cable to Positive (+) terminal on left and work cable to Negative (−) terminal on right.

For Stick and TIG Direct Current Elec- trode Negative (DCEN), connect elec- trode holder cable to Negative (−) terminal on right and work cable to Positive (+) ter- minal on left.

If equipped with optional Polarity/AC Se- lector switch, connect electrode holder cable to Electrode terminal on left and work cable to Work terminal on right.

MIG And FCAW Welding

For MIG welding Direct Current Electrode Positive (DCEP), 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 MIG and FCAW Direct Current Elec- trode Negative (DCEN), connect wire feeder cable to Negative (−) terminal on right and work cable to Positive (+) termi- nal on left. Use Process/Contactor switch to select type of weld output (see Section 6-3).
