5-7. 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 CC (Stick/TIG) terminal on right and work cable to Negative (−) terminal on left.

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

Use Process/Contactor switch to select type of weld output (see Section 6-3).

MIG and FCAW Welding

For MIG and FCAW welding Direct Current Electrode Positive (DCEP, connect wire feed- er cable to CV (Wire) terminal on right and work cable to Work/Negative (−) terminal on left. Use Process/Contactor switch to select type of weld output (see Section 6-3).

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