I remember a few years back or so when Miller did that big roadshow, where they went around to various miller retailers and showed off their products and such, and I saw this one generator there, dont remember what it was called, but it was a fairly large rig, it had arc, mig, and tig fully setup on it, could have had 3 phase on it as well, the generator was massive and had electric motors I think to move it around, and it had co2 and argon tanks on it. Thats all I remember from that, and if anyones seen somethin like that, Id like to here, the machine intruged me and id like to see it again
