Will feed wire but will not start an ark to weld

I was a service tech/manager for 10 years and had my repair business for another 8 years after I left the company I worked for. Can't really remember that exact machine's theory of operation, but check your weld output contactor. Sounds like it might possibly be stuck In the closed position.

Check to see if the wire feed pressure is set correctly. Sounds like it's a little loose.

here's a forum on Hobart welders..hope it helps a little.

Check the selector switch with an ohm meter. Unplug the unit, ground to chassis and probe the contacts while turning the switch on and off.

Check ground connection at welder along with your ground clamp. Bad connection could be the issue. Also check settings on your welder.

hi,
maybe you haven't got the wire speed control turned up probly not the answer but sometimes its the simply things.

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.

Hobart are very obliging, contact them and request a parts list for your set, or any Hobart welding suppliers.

If it is new i would not play around with the welder Just take it back to where you bought it get them to replace it under warranty

check main contactor or diode bank.
