Okay guys, You might remember I had to work on the trigger of my MM175 before. Well, new problem now: half the time when I let off the trigger, it won't stop welding. It keeps feeding wire and stays hot.
I've disected the trigger again, and it looks absolutely fool-proof. I've even insulated the terminals so there is no way it is shorting against anything inside the gun. The trigger is not sticking anymore, it comes all the way back off, and there seems to be no way for it to not break the connection when it does so.
Any ideas? I know that if the problem is in the trigger, the gun is out of warranty. But I'm wondering if it might be in a relay somewhere, in other words, in the box, which is still under the 3-year warranty, right?
I opened the box and could see nothing obvious, so went no further until hearing from the experts.
I'm in the middle of a job where this is the machine of choice, so time is an issue
