TRANSMIG VS 212
OPERATION 4-6 Manual No. 0-4949
5. Contactor And Gas Valve Overcurrent Protection:
If the contactor or gas valve becomes shorted, an
electronic circuit will activate, and both the
contactor and gas valve will not operate. If this
circuit activates, a light on the 12 V driver printed
circuit board labeled [Fault 1] will turn on. The
contactor and gas valve overcurrent protection
circuit will have to be manually reset by placing
the power switch on the wire feeder in the off
position for at least 60 seconds.
CAUTION
If this protection circuit activates, the
contactor or gas valve is most likely
shorted and one or both will have to be
replaced (refer to Section 5.03
Troubleshooting Guide in this manual).
