Something is shorting out in your machine. First you will have to find the short. Good Luck Friend.

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.

I have welded countless hours with Linde & Lincoln & even a few Hobarts & the only time that I ever had the same problem was when the ground connection either to the object I was welding, or the welding cable ground wasn't good & clean & tight. Same on stick welders also. I did develop the habit of grinding not only where I was preparing to weld, but where I was placing my ground clamp & that always provided a better "frying bacon" sound as I went along the business of pushing a bead. In a welder, the only other thing than that is involved is the step-up transformer and your wire. Hope this helps.

First take our the spool of wire, then without any wire restriction, disconnect the gun from the machine and bridge the trigger connection, if the solenoid valve opens then the motor shoulod run. If it does, then check the trigger on your gun, take it off and bridge the cables, if it runs then your trigger switch is faulty.
