New here, did some stick welding (not as a profession) 30+ years ago. Retiring soon and looking to buy a machine to do some work on steel as well as aluminum, on cars, trucks, quads, trailers etc. 1/8"-3/16" tubing as well. Don't see working on anything thicker than 3/8" in either metal but you don't know. Not a fan of buying just big enough to get buy in anything I believe in buying just a tad bigger than needed so I will not run short and will not have to run what I do get at full throttle all the time to keep up. For those times when you need just a bit more.

Millermatic 211 auto set??? , Diversion 180??? , Multimatic w/tig kit??? These are just some I have looked at the most online. I hope some of you can recommend something to me, please do and thanks in advance for your help.......
Buying timeline probably in the next 5 months...
