I pulled an interface board from a customer's machine to replace a shorted transistor. Having no manual for this unit, I made some notes as to where the individual wires hooked up to the board on all the "pl" numbered connections. Somewhere in the interim I managed to lose these notes. I might be able to get the info from Esab the first of the week, but I need to get this installed and tested ASAP. I know a couple of people on this board have said that they had manuals on these units. I desperately need either the whole manual or at least the schematic. If anyone can help me out on this I would GREATLY appreciate it! Again, it's the Airco Heliwelder V (5), 250 amp, Esab-built machine. The main item in question are the connections to the interface PC board.
