*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. Contact your distributor for
the mm2 equivalent weld cable sizes. S-0007-E
3-9. Connecting To Weld Output Terminals
Ref. ST-800 040
Tools Needed:
Use ONLY one negative weld
output terminal at a time.
123
3/4 in
1 Positive (+) Weld Output
Terminal
2 A Negative (–) Weld Output
Terminal (Low Range)
3 B Negative (–) Weld Output
Terminal (High Range)
For DC Electrode Positive (DCEP),
connect work cable to negative (–)
terminal that supplies desired am-
perage range. Connect electrode
holder cable to positive (+) terminal.
For DC Electrode Negative
(DCEN), reverse cable connec-
tions.
