my lincoln 110 has served me well for 9 years now for any and all automotive work. i don't think my bee has any 3/8" steel on it anywhere? of course a 220 will be more versatile and if it's in the budget get one, but my 110 was like $500 and i use it for tons of stuff. don't bother with flux core wire, get a tank of migmix and start welding
