VOLTAGE SENSING
CONSIDERATIONS FOR MULTIPLE
ARC SYSTEMS
Special care must be taken when more than one arc
is welding simultaneously on a single part. Multiple
arc applications do not necessarily dictate the use of
remote work voltage sense leads, but they are strong-
ly recommended.
If Sense Leads ARE NOT Used:
• Avoid common current paths. Current from adja-
cent arcs can induce voltage into each others cur-
rent paths that can be misinterpreted by the power
sources, and result in arc interference.
INSTALLATION
If Sense Leads ARE Used:
• 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.
