ESAB and Miller makes some multi process machines, but myself I don't like the ideal of buying a packaged item...Gives me the feeling of buying a ghetto blaster( and no I'm not talking about the Tommy gun type) that has the cd player tape deck and stero built in one....
stick with the big names, lincon,Miller,hobart,ESAB.
I suggest getting a 220 machine, the little 110 buzz boxes are great if your stuck with 110, but your going to be running it on the edge most the time on much more than sheet metal.
If you can afford it I would suggest one of the "big box" ethier a 210 or 250 amp range...once and for all kind of buy....but any of the 175-180 machines are great too for pretty much eveything with in reason.And semi portable.
weldingweb.com has alot of good info on buying a machine to suit your needs.
also if you looking to save a few bucks, sometimes places like toolking.com will have refurbs,same warranty as a new one....
Blackbronc funny you say that about the lindes, I have a old linde 225 mig,single phase and the thing will spray like no tomorrow.
