I-tig 200T help!!!! Has mind of its own

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.

Only remove screws on the sides and rear, the front stays in place. Barely snug when you put them back.

called in and spoke with tech support. we walked through a few possible options, none of which did anything. The first step in getting the issue resolved, is trying a new logic board.

there is no pattern to the issue that i can find. when i was on the phone it switched from program 2 to 6 while twisting the dial knob. then it stayed on program 6, but the program button would not function. all other buttons functioned properly. the HF start still does not kick off. with either HF or lift start selected, i only get an arc while lift starting. also noticed with pedal plugged in the amps switched to 2 until i clicked the knob to change amps, then back to 2 after a few seconds. never noticed if that happened in the past. i thought it always displayed peak amps when idle. when the torch switch is plugged in, it displays peak amps.

any who, the saga continues. hopefully it will stay on 1 program tonight, and i can get some more work done. being that i have never scratch started when tig welding, i am killing my sharpened tungsten pile. new skills are developing

That unit has a single board, besides the display, touch panel board.
