I'm having problems with my pos welder. I'm usually better than ok with electrical. But the diodes died in my welder. Cheap pos. I don't want some b.s. I need a fix. Bought some real diodes. I need a quick wiring schematic for a rectifier that works. Been all over the world. Too confused to get it sorted out.

I have got that in a note book from airframe and powerplant school 20 years ago. If you still need it can dig it out for you.

Thanks for the reply. I said f-it and put in a unitized rectifier and two big ass capacitors along with two fans and my junk China built welder runs great. Wouldn't quite call it a good machine but it has a lot more punch and a stable arc. Had to learn to move faster while welding thinner materials. Much cleaner weld with the capacitors. If you don't have capacitors on the output side of your mig I highly recommend them. I'm running two 50000 micro farad caps in parallel and the splatter is all but eliminated.

1 of my 3 blue welders, the barely used 211 multimatic, lays a bead down that doesn't penetrate at any setting & makes the user look stupid. Repair shop says there's nothing wrong with it.
It ain't just the cheap ones anymore.

Cheap Amazon rectifier does the trick. I buy a couple at a time and consider them consumable. About 10 bucks a pop.
