Voltage Sensing overview
Certain welding process requires the use of remote
voltage sense leads to more accurately monitor the
conditions of the arc. These leads originate in the
power source, and are connected and configured
through the Advanced Module. Consult the connec-
tion diagrams included in this manual for detailed
information.
note:
OtherprocessesrunthroughtheAdvancedModuledo
not necessarily require sense leads, but will benefit
from their use. Consult the power source instruction
manualforrecommendations.

RECOMMENDATIONS:
• Position the sense leads out of the path of the
weld current. Especially any current paths com-
mon to adjacent arcs. Current from adjacent arcs
can induce voltage into each others current paths
that can be misinterpreted by the power sources,
and result in arc interference.
• For longitudinal applications, connect all work
leads at one end of the weldment, and all of the
work voltage sense leads at the opposite end of
the weldment. Perform welding in the direction
away from the work leads and toward the sense
leads.
