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 strongly recommended.
If Sense Leads ARE NOT Used:
• Avoid common current paths. Current from adjacent arcs can
induce voltage into each others current paths that can be
misinterpreted by the power sources, and result in arc inter-
ference.
If Sense Leads ARE Used:
• Position the sense leads out of the path of the weld current.
• For longitudinal applications, connect all work leads at one end

opposite end of the weldment. Perform welding in the direction
away from the work leads and toward the sense leads.
