A schematic would certainly help, give Hobart a call and ask for a wiring diagram. or manual. Hobart are very helpful and may even give you guidance, you may have to pay the postage, they usually fax these documents so it will not cost you anything.

Get a volt meter, go to ohms setting , check transformer to ground for low to zero ohms reading. also look closely at transformer windings for foreign objects in between them, never know what you my find. If transformer is shorted to ground probably time to say some nice words over it before burial. Also just for kicks try a new gun on it, (there is a reason i'm asking you to do(this) see if you can find someone that has spare. A good honest repair shop would probably be reasonable if all else fails. to a least let you know if the transformers a problem. good luck

The problem with my MIG 175 Pro is the
"voltage selector switch" (part # M15750-1). I took it apart and
saw all of the contact points where corroded. I can hold the knob between
two settings and the machine will work.
I have the same issue only after about a year of very light use. I am not sure how to prevent this from happening again.
