Hobart Handler 120 Mig Welder

[Willy P]

I have a Hobart Handler 120 mig welder and I am having trouble with it. It won't weld! Turn the switch on and mash the handle and you can hear it clicking but the wire won't come out,checked the wire and it is free but the little wheel that feeds the wire will not turn,it will turn with a screwdriver but won't with power. What is the problem?Any help would be appreciated.

You have popped a diode or two.I have replaced them in mine a couple of times.Not too big of job if you have an ohm meter and can solder. Cost about 25.00 bucks each.

Thanks Weldingman,but where are these diodes and where can I get them at?

Dang,mine did that awhile back,tinkered a bit and it's been going ever since....BUT..I don't
recall just what ir was...it was simple(corroded connection,loose wire??),but I know I didn't need any new parts.
