So went to fix the brakes on a IH 584 today. Got to talking to the guy and he has this cheap Chicago electric mig welder. Well it turned on and all but when you hit the switch on the handle you got nothing. Opened up the handle area and found a super simple cheap switch that worked if you held you mouth just right. Pull the switch out and found that out of the handle it would work just fine but in the handle it would not. The guy said heck leave it that way and I'll tape it up. He was happy with it that way so if you have a problem with a 110 volt mig welder by that company take a look at the switch in the handle
