Let me know how it goes with the control, that is one of the models I looked at when I was shopping.

If I had it to do over again I think I would have bought one of those Everlast Chinese Inverter TIGs that do pretty much anything you can imagine. Since I'm retired it's not like I depend on my machines for income so reliability is not as much of an issue. Instead I sold my 25 year old Syncrowave 250 for enough to buy a brand new Lincoln 200 amp TIG.
I’ve already begun the reverse engineering lol. I don’t know why I expected to see a rotary instead of linear. It’s cool to see how they used the slider itself to open/close the on/off trigger independent of the potentiometer itself. Trying to keep myself off the Mouser and Digikey websites. I found a cool looking linear with a spring return that would be interesting. It would be nice to have a slide that you could push against as you slide your thumb up/down the torch and have it return back to “off”. Seems like you could have more precision instead of your thumb on some slider just “floating” out in space.

If I could sort out the “simple” stuff I could work my way up to your audrino “premium” model haha. Spectra Symbol Softpot or Thinpot membranes.

I have an import IGBT (Primeweld TIG225x) and an HTP Invertig 221. I haven’t had too much time on the HTP yet. I only decided to upgrade to the HTP because a buddy from work was always on me to sell him the Primeweld and I wanted digital instead of analog control over my pulse functions (I use pulse way too often lol). Of course as soon as I got the new TIG my buddy changed his mind so here I sit with 2 until I find a new home for it.
