Tig welder
Look into PrimeWeld welders. I bought their Tig225 over a year ago. AC and DC, pulse settings, works flawless and great customer support from others I've talked to that have needed it. For less than $1k you get a really nice welder. I bought mine through Weldmonger when they had a sale before Christmas back in '23. Made my own cart, but HF has cheap ones too.
