5-12. Making Dual Operator CC And CV Weld Connections w/ Common Work Cable
Ref. 251 340-A / Ref. 802 292-A
!
Stop engine.
!
Failure to properly size and connect
weld cables may cause excessive
heat and start a fire, or damage your
machine.
NOTICE − When making weld connections
with a common work cable, connect weld
cable of adequate size between Negative
(−) weld output terminals, and connect a
single weld cable of adequate size from
Welder B (right) Negative (−) terminal to the
workpiece.
NOTICE − When using these connections
as a common work terminal, all connec-
tions must be of the same polarity.
NOTICE − For common work connection,
work cable must be able to carry combined
weld output of both modules (see Section
5-14 for proper cable size).
NOTICE − Do not exceed machine duty
cycle.
Use Dual Operator mode for CC and
CV welding (see Section 6-2).

Common Work Cable
For Direct Current Electrode Positive
(DCEP), connect common work cable and
work jumper cable to Welder B (right) Neg-
ative (−) terminal. Connect other end of
work jumper cable to Welder A (left) Nega-
tive (−) terminal.
Connect electrode holder cable to one Pos-
itive (+) terminal.
Connect wire feeder cable to remaining
Po) terminal.
Be sure Process Selector switches are
set correctly. See Section 6-4.
For Direct Current Electrode Negative
(DCEN), connect common work cable and
work jumper cable to Welder B (right) Posit-
ive (+) terminal. Connect other end of work
jumper cable to Welder A (left) Positive (+)
terminal.
Connect electrode holder cable to one
Negative (−) terminal, and wire feeder
cable to remaining Negative (−) terminal.
Be sure Process Selector switches are
set correctly. See Section 6-4.
Tools Needed:
3/4 in.
