For Stick welding Direct Current
Electrode Positive (DCEP), con-
nect work cable to − terminal and
electrode holder cable to +
terminal.
For Direct Current Electrode Neg-
ative (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
