thanks! thats the kind of explanation i need. i will try that tonight and report back.

thanks, I have the owners manual that two of you referred to. I was looking for something more technical, that might give specifications for different components, or give a test procedure for different components. example: check for voltage at switch "A" when selector is in "medium&qu...

Thanks, since my first post I tried to by pass the welding lead ( even thought the micro switch in the trigger checked out and seemed to work). I jumped the two wires just before the relays inside the welder, to simulate pulling the trigger. Same result, wire feeds, gas flows, but no arc. I can see ...

Thanks for the reply. There are only 4 "wires" that go to the selector switch (more like flat bar stock) I labeled all of them before removal.

You are right a pic is a great idea. I have looked at other pics on the net, mine is connected the same.
