OT here,
The Welder is a 1994 Miller Syncrowave 250. The circuit board is PN 138307 and has now been repaired at York Electronics a few times.
The visual damage was to a resistor and at least one 14 pin IC. York socketed all the IC locations and mass replaced them. I have no clue if or how they test the boards. I am not sure they do test them. For $300+ I could have replaced the $20 worth of ICs myself. At this time the contactor closes but there is no output. The welder did run intermittently for ¢ hr after the first time they had the board. Whenever the machine is set to remote control the High frequency is active. The local welder repair guy just says I told you so about board remans and will not come by to diagnose the welder. I think circuit board remans are in the same class as engine remans. Replace all and hope.

Not always. If the components can be gotten, I can certainly replace them. If they're common items, I prob already have them in stock.

If you want to mail it to me, I will see what I can do. Worst case scenario, I replace a buncha stuff, and it doesnt work, and you're out shipping. <img src="/forums/images/graemlins/kewl.gif" alt="" />

I bet it I replace the smoked components, it will work great. <img src="/forums/images/graemlins/wink.gif" alt="" />

Here is a pic of the board taken minutes ago,
Everything was socketed by York, most of the IC are LF347H



I can ship this down to you tomorrow. I do want to spend some time inside the welder to see if there could be anything else that could be an issue.
Heck the shop is still warm since I just finished welding on a Land Rover chassis so maybe I will go back down there.

being a guy who did board repair for a living on a military base that board looks easily fixable. just a few board mount resistors and thru mount caps nothing to throw the board out over. <img src="/forums/images/graemlins/kewl.gif" alt="" />

This is just a simple two layer board. Looking at it right now I question the quality of some of the solder joints the repair company did.

Believe me, I worked with people who are 30 year experience for the federal employed side and they knew nothing about soldering and they did it for a living... I find its either you can or you can't when it comes down to it. <img src="/forums/images/graemlins/lol.gif" alt="" /> People also tend to not clean flux up after soldering too <img src="/forums/images/graemlins/barf.gif" alt="" />

I hope you guys can get Charlie's board fixed up 'cuz I'm definitely down for a couple tanks depending on final cost. Good luck with the fix! <img src="/forums/images/graemlins/kewl.gif" alt="" />

Just wondering, but are baffles inside the tank needed to keep all that gas from sloshing around? Edit (just re-read and see baffles are in there)

couldn't tell from the pics, but where did you re-route your exhaust to?
