4-8. Connecting To Weld Output Terminals
802 729
Y Stop engine.
1 Positive (+) Weld Output Terminal
2 Negative (–) Weld Output Terminal
For Stick and TIG welding Direct Current
Electrode Positive (DCEP), connect
electrode holder cable to Positive (+) ter-
minal on left and work cable to Negative
(–) terminal on right.
For Direct Current Electrode Negative
(DCEN), reverse cable connections.
If equipped with optional polarity switch,
connect electrode holder cable to Elec-
trode terminal on left and work cable to
Work terminal on right.
For MIG and FCAW welding Direct Cur-
rent Electrode Positive (DCEP) on CC/
CV models, connect wire feeder cable to
Positive (+) terminal on left and work
cable to Negative (–) terminal on right.
Use Process/Contactor switch to select
type of weld output (see Section 6-3).
For Direct Current Electrode Negative
(DCEN), reverse cable connections.
If equipped with optional polarity switch,
connect wire feeder cable to Electrode
terminal on left and work cable to Work
terminal on right.

* This chart is a general guideline and may not suit all applications. If cable overheating occurs (normally you can smell it), use next size larger
cable.
**Weld cable size (AWG) is based on either a 4 volts or less drop or a current density of at least 300 circular mils per ampere.
