More of the same. Don't even have to press button or spin dial. Will do it all on it own. There is like an invisible grimmlin screwing with my welding.

You can check for loose connections on the boards, but I get the feeling that you will have to send it in for service. Very odd.

I REALLY hope I don't have to send it in. I needed to finish this project this weekend. Sending in is atleast 2 weeks just in transit. Will opening the machine void any type of warrenty?

No it wont. Sounds like a loose cable.

So I opened the cover and pressed the connections from the front panel and the opposite end of the cable that connects to the upper board. And pressed on all the other connections I could get to. Put the cover back on and fired it up.... No dice. However. It did stay on 1 setting for a while and got some work done. HF start no longer works. Had to lift start even when HF was selected. Then randomly it went back to crazy mode and shot a hole through my piece at like 180 amps and then I watched the display panel go wild. Sitting here thinking about it really pisses me off.

The good thing about it, is that you can call in today. Likely it would be something that you could fix as that unit is mostly plug and play. Last one I had did have a soldered ground wire to the board, but that is an easy fix. The modular components make self service easy (and a whole lot quicker these days), if the problem can be isolated.
