Welder advice - where to start

If you get a 110v unit then when you go to weld up a stand or fab up something that is 1/8" metal because now you are a good welder, your 110v unit is running balls out and not doing the job or just burns up now you are off to buy a new one.
You are correct. I started with a Lincoln 220v welder, then I added a 110V Lincoln welder

I abuse the hell out of the duty cycle on both machines and they have been absolute champions.

my 110v welder is the only one hooked up to my 75/25 bottle at this point and even though I run it flat out often i can't kill it.

I have a buddy who is a red seal/B pressure welder and he tossed his tig welder aside to use my Lincoln 110v when he helped me weld up my quarter panels
