!
Turn off welding power
source and weld control, and
disconnect input power be-
fore making connections.
.
Use remote voltage sense
leads in all applications.
.
Suggested size for remote volt-
age sense wire is 12 gauge or
larger.
.
For better performance for
most Sub Arc (SAW) applica-
tions, make connections to the
high inductance weld output
terminal.
.
Polarity: For DCEP (Reverse
Polarity), connect weld cables
and voltage sense leads as
shown. For DCEN (Straight
Polarity), reverse weld cables
and voltage sense leads.
