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