REMOTE SENSE LEAD SPECIFICATIONS
Welding with Multiple Arcs
Special care must be taken when more than one arc
is welding simultaneously on a single part. Arc blow
and arc interference may occur or be magnified. Each
power source requires a work lead from the work stud
to the welding fixture. Do not combine all of the work
leads into one lead. Perform welding in the direction
away from the work leads. Connect all of the work
sense leads from each power source to the work
piece at the end of the weld, such that they are out of
the path of the weld current.
For the best results when pulse welding, set the wire
size and wire feed speed the same for all the arcs.
When these parameters are identical, the pulsing fre-
quency will be the same, helping to stabilize the arcs.
