Hello,
I've got this Lincoln Square Wave 300 welder, and it needs a little work. I downloaded the user manual from Lincoln, but it only goes so far. I think there are a couple of capacitors in some of the timing circuits that need to be replaced. (For instance, if you set the postflow timer over 10 seconds, it really leaves the gas on FOREVER. I've already wasted $10 of argon with this.)
I notice Miller puts the complete electronic schematics of their machines in their manuals, very unusual! Is there any place to get schematics for the Lincoln machines? Or, any place I can just find out which capacitors are in which timer? (I can trace all this out, but it would take more than a few hours, though.)
Thanks much in advance!
Jon
