So.... I hate to admit this, as the idiot owner, but I f ed up my passport. Here's what I did. Drilled thru case, to remove a bolt whos head had snapped off. Not using my brain, when I broke thru the backside I kind of dimpled the pc1. The main control board. Now the welder is running the feed motor at full speed when trigger is pulled. The Ipm knob does nothing at all. If I hold trigger for more than a second the motor starts smoking. I really need this machine and I'm going to fix the board myself. If you guys/gals can think of anything I can test i have a DMM and can use it. I'll grab some pics of the results of my work lmao. Thanks guys.

Reply:Think you are SOL. there are no diagrams of the pcb published any where and all certified Miller techs are forbidden from sharing any Miller tech manuals.The pcb might be a multi layer pcb There could be 2 or more circuit where you drilled in to. Not sure if the pcb is still available and if it is a new welder will only cost a little more.
