Amazon has a 3 in one right now, pilot arc plasma, stick and tig. I understand that this sort of tig welding isn’t ideal but I think I might give it a try with this machine. It is inexpensive and for the amount of times I will use it in any given year I am sure it will be good enough. The only “bad” thing I can find is its consumables are kind of proprietary and it goes through them quickly, but if I switch out the “gun” for a pen style plasma torch I hope that will help both of those. Add a foot pedal and maybe have a decent functional scrape start tig welder?
