Current flow from trail affects lead
sense.
Neither sense lead picks up the
Trail correct work voltage, causing
starting and welding arc instability.

Lead sense is only affected by
weld current from lead.
Trail sense lead is only affected
by weld current from trail.
Due to voltage drops across work
