This arrangement is a bad setup due to
sensing leads being directly in the current
flow path of the welding arc. Interaction
between welding circuits will affect voltage
drop in the workpiece. The voltage drop

across the workpiece will not be measured
correctly for the voltage feedback signal.
Voltage feedback to the welding power
sources will not be correct at either sense

quality.
