Check your manual, there are a lot of mig units on the market that are alway "Live" alternatively, the relay has either shorted or you have wirering problem on the switch.

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.

This welder is made in China. I have one and it works fine. Parts and service are available from northern tool. 1-800 # is on the book. FYI this 135 gas no gas looks exactly like the Lincoln SP135 and Lincoln workmate 135. GOTO the lincoln site and bring up the manual. It is a free download and is a much better manual than the one it came with. I agree with the previous post. Put a continuity test on the 2 wires that come from the trigger. there is a wire diagram in the book that came with it. Hope this helps.

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
