I don't know shit about this machine other than what I just read when I looked it up. Hell, if you have 3k burning a hole in your pocket, why wouldn't you buy it? AC/DC tig, stick, mig, ability to spool gun aluminum, auto settings and DVI. Plus, it's a Miller. I'm a Lincoln guy myself, but it's not like your asking about some off brand crap. Lincoln/Miller can't go wrong.
And, who the fuck references seller distance in km?
