Yes sir. It's U502295
I have checked all components and am very confident this welder will work. When I got it somebody had started the teardown and I got a bunch of parts in a box. I sure thank you for any help

I bought an older big 40 to restore and have been looking for wiring schematics. I looked on the miller website but I guess it's to old to look up. Im specifically trying to see how the bridge rectifiers are wired up. I have all four brushes connected but the other terminals is where I get lost. Any help will be greatly appreciated.

Could you PLS post your serial #

Can't help ya without it.....
