3 Negative (–) Weld Output Ter-
minal
For Stick welding Direct Current
Electrode Positive (DCEP), con-
nect work cable to (–) terminal and
electrode holder cable to (+)
terminal.
For Direct Current Electrode Nega-
tive (DCEN), reverse cable
connections.
If equipped with optional polarity
switch, connect electrode holder
cable to Electrode (–) terminal and
work cable to Work (+) terminal.
For MIG and FCAW welding with
CV option, connect work cable to
(–) terminal and wire feeder cable to
(+) terminal
