I have a hobart 140 but it won't stop feeding the wire without pulling the trigger?

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.

You need to look at the wiring diagram to see what parts could be causing the problem. I had a 120 that did the same thing and it was the bridge rectifier that was bad. I unhooked my motor and hooked it to my battery charger to see if it was good.Hope this helps. I will see if I can find a diagram to look at and check back later to see if you have fixed the problem.

Sound like you have a bad trigger on the gun. Does gas spray when you pull the trigger? Check the wire plug that goes from the pistol to the unit. It should be under the liner hose where it connects to the machine. Then use a voltage meter on the wires going to the drive feed motor, and see if you get current when you pull the trigger. If gas doesn't spray neither, sounds like you got a bad trigger switch
