4-9. Making Dual Operator Mode CC Weld Connections w/ Common Work Cable
Ref. 190 377 / 802 292-A
Y Stop engine.
Y 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 4-15 for proper
cable size).
. Use Dual Operator mode for CC and
CV welding (see Section 5-1).
1 Strain Relief
Route cables through strain reliefs.
2 Electrode Holder Cables
3 Work Jumper Cable
4 Common Work Cable
For Stick/TIG welding Direct Current Elec-
trode Positive (DCEP), connect common
work cable and work jumper cable to Weld-
er B (right) Negative (–) terminal. Connect
other end of work jumper cable to Welder A
(left) Negative (–) terminal.
Connect electrode holder cables to CC ter-
minals.
For Stick/TIG 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) CC ter-
minal.
Connect electrode holder cables to Nega-
tive (–) terminals.
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 cables to Elec-
trode receptacles.
. Be sure Process Selector switches
and optional Polarity switches are set
correctly. See Section 5-3.
Tools Needed:
Welder A (Left) Side
3/4 in
Welder B (Right) Side
Y INADEQUATE CABLE CONNECTIONS can cause serious damage to welding generator and create a hazardous condition.
When making weld connections with a common work cable, connect a weld cable of adequate size between the Negative (–) weld termi-
nals, and connect a single weld cable of adequate size from the Welder B (right) Negative (–) terminal to the workpiece.
When using these connections as a common work terminal, all connections must be of the same polarity.
For a common work cable connection, the work cable must be able to carry the combined weld output of both modules (see Section 4-15
for proper cable size).
