5-13. Making Dual Operator CC And CV Weld Connections w/ Common Work Cable
Ref. 225 543 / 802 292-A
! Stop engine.
NOTICE − Do not exceed machine duty
cycle.
. For common work connection, work
cable must be able to carry combined
weld output of both CC weld output ter-
minals (see Section 5-15 for proper
cable size).
. Use Dual Operator mode for CC and
CV welding (see Section 6-1).
1 Strain Reliefs
Route cables through strain reliefs.
2 Electrode Holder Cable
3 Wire Feeder Cable
4 Work Jumper Cable
5 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 either
CC terminal.
Connect wire feeder cable to CV terminal
on other side.
. Be sure Process Selector switches are
set correctly. See Section 6-3.
For Direct Current Electrode Negative
(DCEN), connect common work cable and
work jumper cable to Welder B (right) CC
terminal. Connect other end of work jumper
cable to Welder A (left) CV terminal.
Connect electrode holder cable to either
Negative (−) terminal, and wire feeder
cable to remaining Negative (−) terminal.
If unit has the Polarity switch option, con-
nect common work cable and work jumper
cable to Welder B (right) Work receptacle.
Connect other end of work jumper cable to
Welder A (left) Work receptacle.
Connect electrode holder cable to either
Electrode receptacle.
Connect wire feeder cable to CV recep-
tacle on other side.
. Place optional Polarity switch in Re-
verse position when using CV weld re-
ceptacle. 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.
Tools Needed:
Welder A (Left) Side
3/4 in
Welder B (Right) Side
! INADEQUATE CABLE CONNECTIONS can cause serious damage to welding generator and create a hazardous condition.
D When making weld connections with a common work cable, connect a weld cable of adequate size between the Negative (−)
weld terminals, and connect a single weld cable of adequate size from the Welder B (right) Negative (−) terminal to the work-
piece.
D When using these connections as a common work terminal, all connections must be of the same polarity.
D For a common work cable connection, the work cable must be able to carry the combined weld output of both modules (see
Section 5-15 for proper cable size).
