I have a Plasma cutter - Hypertherm powermax 1250 which ceased to work. I've sent it to a repair shop, they checked it and they told me that the power board (part no. 128663) and the Pcf igbt (part no. 228071) are faulty and need to be replaced. the repair cost? you don't want to know! I would like to ask for your help. if you know where these boards can be fixed or if you know a source to purchase these parts - second hand, repaired, whatever, please let me know. also if any of you forum members, have or know where I can find the schematic diagram of the board(s) - that might be a great help too.
