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
OM-262 752 Page 32

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.
