5-12. Making Dual Operator CC And CV Weld Connections w/ Separate Work Cables
Ref. 190 377 / 802 292-A
Y Stop engine.
Y Do not exceed machine duty cycle.
.
Use Dual Operator mode for CC and
CV welding (see Section 6-1).
See Section 5-15 for proper cable size.
1 Strain Reliefs
Route cables through strain reliefs.
2
Electrode Holder Cable
3 Wire Feeder Cable
4 Work Cables
For Stick/TIG welding Direct Current Elec-
trode Positive (DCEP), connect work cable
to Negative (−) terminal and electrode hold-
er cable to CC terminal.
For Stick/TIG Direct Current Electrode
Negative (DCEN), connect work cable to
CC terminal and electrode holder cable to
Negative (−) terminal.
.
Be sure Process Selector switches are
set correctly. See Section 6-3.
For MIG and FCAW welding Direct Current
Electrode Positive (DCEP), connect work
cable to Negative (−) terminal and wire
feeder cable to CV terminal.
For MIG and FCAW Direct Current Elec-
trode Negative (DCEN), connect work
cable to CV terminal and wire feeder cable
to Negative (−) terminal.
For Stick/TIG welding on units with Polarity
switch option, connect work cable to Work
receptacle and electrode cable to Electrode
receptacle.
For MIG/FCAW welding on units with Polar-
ity switch option, connect work cable to
Work receptacle and wire feeder cable to
CV receptacle.
.
Place optional Polarity switches in Re-
verse position when using CV weld re-
ceptacles. There is no CV weld output
when switch is in Straight position.
.
Be sure Process Selector and Polarity
switches are set correctly. See Section
6-3.
