it quit working, and it looks like the circuit board got pretty hot.
Aweman do you have any knowledge of these?

No Mark Unfortunately not!
About all i`m used to are the Industrial welders. And if one of them broke down we called the Millwrights to come service it. And Yes even on the industrial machines it is quite common for the boards to quit. I do have the Hobart 180 for home use and we did have a lincoln 180 in the shop for the Body and fender guys to use. However I never used it, {it was forbidden} we Welders coudn't use the 180 for anything requiring a certified weld. As far as the circuit boards go, I wouldn't know where to begin other than contacting the Mfg. and asking if a replacement board is available or if they could recommend a repair service jobber.
If you, or you know someone that is electronics savy you might be able to test the board components, I know, a long drawn out process. If you decide to try it, start with the components nearest the discolored areas that got hot. Transistors are usually the culprit. Especially the ones near any heat sinks. Finding replacement transistors may be a whole different ball game!
It's been my experience and what I have been told by our Millwrights is that running the machine for extended periods of time beyond their duty cycles is normally what causes the boards to go south. Yes even industrial machines have duty cycles!
The higher end machines will usually take quite a bit of abuse where as the lower end ones not so much.
If you have an owners manuel for that machine, there is a good chance a parts list may be included, usually on the last page or pages
Sorry I can`t be more help
