Thinnest I've used it on is 1mm so far with .6mm wire. Needs to be on the lowest setting for this, there are only 4 power settings rather than an adjustable knob. I actually found this better (as a novice) as it gave me less things to fiddle with and just focus on technique. You can still fiddle with the wire speed however.
I've actually used the slightly bigger co2/argon bottles from machine mart with one of their valves.
Like i said, i'm a novice and not qualified to give anything other than my personal experience (and this is my first welder) but it seems OK to me.
