5-6. Connecting To Weld Output Terminals
803 596−B / 803 778-A
1 Positive (+) Weld Output
Terminal
2 Negative (−) Weld Output
Terminal
For Direct Current Electrode Posi-
tive (DCEP), connect work cable to
Negative (−) terminal and electrode
holder to Positive (+) terminal.
For Direct Current Electrode nega-
tive (DCEN), reverse cable con-
nections.

6 Copper Bar
Remove supplied nut from weld
output terminal. Slide weld cable
terminal onto weld output terminal
and secure with nut so that weld
cable terminal is tight against cop-
per bar. Do not place anything
between weld cable terminal
and copper bar. Make sure that
the surfaces of the weld cable
terminal and copper bar are
clean.
