Ello everyone. I'm in need of information. I need to see how the pwm card wires from the inverter(?) go like. Top pcb is with part number pn-12-a0 and pwm card is PK-09-A0. Need to verify both top and bottom wires how they go to the connectors and the pcb sides. I have a reason to believe a botched repair was the cause of the new failure on this one. If you have a newer card i have an assumption to believe it doesn't really matter as long it has 4 red and 4 black wires split into two connectors. Presumbly the same inverter and pwm boards are used in chinese pulsed migs too. TIA, Teemu
