5-12. Making Dual Operator CC And CV Weld Connections w/ Separate Work Cables
Ref. 225 543 / 802 292-A
! Stop engine.
NOTICE 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 elec-
trode holder 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 Elec-
trode receptacle.
For MIG/FCAW welding on units with Po-
larity 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 Sec-
tion 6-3.
