I picked up a Dual 180 mig welder. When I plug in the 230v plug, the wire roller moves and feeds and it looks like the gas is on also. I checked the polarity connections and even opened the gun to verify the trigger isn't depressed. Suggestions?
Thanks
Where the gun whip connects to the welder box disconnect the smaller wire and plug... also does this same thing happen when you use the 120v plug??? the way your post is written kind of hints it doesn't... if it still does this after disconnecting the smaller wires then could be a short inside the box or stuck relay.Quote:

I would guess 120v plug will do the same...Quote:

The spring behind (inside) the trigger is mushy soft.
Maybe you have the same issue, , , ,

Buy a new trigger for your gun. will come with a new spring i think.Quote:
