I have a 2000 model Miller Maxstar 91 and it doesnt work. It arcs but not hot enough to do anything. I took it to the local repair shop and they said I needed a new board but they couldnt find one. Does anyone know where I can get part #175943 (PC1) or of a place that repairs boards?

I have tested the machine with new cables and all but it still didnt change, it just gives a small arc not hot enough to barely scar aluminum.
