Did you check if the contactor has power in and out. Seen a lot of them that had power in but not out.
Yes, no power in or out. I could try and start checking capacitors but that is getting a little above my knowledge. Also I am not sure if i am checking the transformer correctly.
Does the gas flow at that time?
Is there a wiring diagram on the inside of the cabinet?
Does it say what the input output should be on that transformer?
yes the gas flows, ground is good I never heard a pop or any strange noise when it stopped working but I felt like a few seconds before it died it was dying slowly.
Guys I know this is the Plasma Forum. I have been on the Miller forum with no help, but can anyone explain to me why this thyristor (T50RIA40) is so hard to get? I am going to throw one part at it before I bring it to a Miller service center. Look at the disclosure on the bottom of the email reply I received from one company. I have searched the web for the part and every website that says they have it, I cant just buy it, they are saying they will reply to my inquire. Plus the wording from this company is a little weird.
It looks like the problem is more getting one of them instead of having to buy 10 or more and waiting 10 weeks.
Here’s a place you can buy one of but you’re still going to have to wait

I thought I was doing something wrong. What is with these things? are will still in the COVID chip shortage era?
Is this the one your looking for
Its just a diode. If you check the plug it the ground and the - and +. Did you test it with a meter?
@mechanic416 there is voltage going in one side but nothing coming out when i pull the trigger. I just have a multi meter. I am not exactly sure what I even should be reading. The wire diagram doesn’t help much with that. I believe it still should be AC and then after the rectifier turn to DC. I thought the small wire opened it up to allow voltage to go through when I pull the trigger but I may not be understanding how it works. I thought it worked like a solenoid little wire lets power go through big wires.
Or switch the polarity, might be DCEN when you need DCEP
