I've given up on XMT350s for the same reason. I'm pretty disappointed in Miller... Using proprietary parts, offering a short warranty, and then selling the parts for absurd prices. Makes green welders look like a really good option...

pc7 Flyback 266586 $ 384.85 also if you have a cooler PC that might be pulling down the voltage unplug it and try to power it up.

You most likely have a bad PC7 power supply board be careful there is very high DC voltage on that board.

How can I tell if I have the 220 volt 15 amp 1.5 KVA or the 220 volt 30 amp 2.5 KVA Miller spot welder with the label missing?​

Beginner Welder here - So farI have been working on just thick steel applications. I have a need to do the smallest amount of Aluminum welding. I need a simple butt joint about 8 inches long.

I am running Miller 211 machine. Internet research tells me I need a spool gun.

Question...

Hello, I bought a welder locally where they said it worked but there was just a very low spark, it can't melt metal. I took it as a learning project and assumed it just needed new diodes, and hoped the transformer was ok. At $100 I thought it would be a good gamble.

I did some reading on...

This is one of two John Deere rear fenders that customer states new ones for this model are not available, model unknown to me. Final product to be nice but not overly nice. Numerous rust and cracks so I decided to replace vs fix. Pic 1 bottomed rotted and numerous cracking where it bolts on plus...

I was using this spot welder when it blew the circuit breaker and the switch on the spot welder started to smell like a burnt smell. I think I have a bad ground in the timer perhaps.

Should there be continuity between the two area I highlighted in red?
