Failure to properly size and connect
weld cables may cause excessive
heat and start a fire, or damage your
machine.
NOTICE − Do not connect weld cables in
this configuration if using SF feeders with
a Big Blue 700 Duo Pro DLX SF.
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.
.
For common work connection, work
cable must be able to carry combined
weld output of both CC weld output ter-
minals (see Section 5-14 for proper
cable size).
.
Use Dual Operator mode for CC and
CV welding (see Section 6-2).

For MIG and FCAW welding Direct Current
Electrode Positive (DCEP), connect com-
mon work cable and work jumper cable to
Welder B (right) Negative (−) terminal.
Connect other end of work jumper cable to
Welder A (left) Negative (−) terminal.
Connect wire feeder cables to Positive (+)
terminals.
For MIG and FCAW Direct Current Elec-
trode Negative (DCEN), connect common
work cable and work jumper cable to Weld-
er B (right) Positive (+) terminal. Connect
other end of work jumper cable to Welder
A (left) Positive (+) terminal.
Connect wire feeder cables to Negative (−)
terminals.
.
Be sure Process Selector switches
are set correctly. See Section 6-3.
