My old PC3500 from Harbor Fright quit cutting so I opened it up and found just fragments of what looked like a diode, scattered around inside the unit. After examining the circuitboards, I found two holes shere the part had unsoldered its self and flew out of the board. I could'nt find enough of the pieces of the part to identify it, so I tried contacting harbor fright for parts or a schematic. They were no help, so I started searching the internet and found George. He went right to work and found a complete circuit board in his shop, and gave me the part numbers and instalation polarity, and where I could buy the diode for 63 cents. I got the diode and soldered it in, and my cutter works great ! I offered to send George somthing for his time, but he said " just think of me if you need to buy another plasma cutter or any parts". Thank you George for your expert help and for saving me the cost of a new machine.
