Insulation resistance (supply circuit to welding circuit)
The insulation resistance test checks the resistance between primary supply circuit and
the welding circuit (outputs) of the welding machine.
The instrument measures the insulation resistance between:
-
mains test socket‘s live terminals and W1/ W2_TOUCH terminals on 3-phase
adapter (A1422).
