    Chicago electric 180 amp mig

    Last year I bought a harbor freight 180 mig and used it for about 4 months, and decided to put on a longer torch, so ordered a 10 footer and installed it, fired up the welder and it worked great, for about 2 inches of weld, I tossed it aside and bought a new 3 in 1, but now I'm kind of curious as to what may have happened to the 180, it's completely dead, no fan no spark, nothing any help would be great, Thank you.

    Usually the fan runs off of the input power, so I would suspect the switch.

    That would be my guess too.

    I will have to check that, I just figured maybe something with the new mig gun, it seemed to be a good little machine up to that point.

    After looking at the schematic can be just the main switch or in the rotary switch it can even be a loose wire
