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-
faces of the weld cable terminal and cop-
per bar are clean.
Stick and TIG Welding
For Stick and TIG welding Direct Current Elec-
trode Positive (DCEP), connect electrode
holder cable to Positive (+) terminal and work
cable to Negative (−) terminal on left.
For Direct Current Electrode Negative
(DCEN), reverse cable connections.
Use Process switch to select type of weld out-
put (see Section 6-3).
MIG and FCAW Welding
For MIG and FCAW welding Direct Current
Electrode Positive (DCEP), connect wire
feeder cable to Positive (+) terminal and work
cable to Negative (−) terminal on left. Use Pro-
cess switch to select type of weld output (see
