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 Work/Negative (−) ter- minal 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.

Remove supplied nut from weld output termi-
nal. Slide weld cable terminal onto weld output
terminal and secure with nut so that weld cable
terminal is tight against copper bar. Do not
place anything between weld cable termi-
nal and copper bar. Make sure that the sur-	2
faces of the weld cable terminal and cop-

per bar are clean.	1
