hey i gotta agree, it is one honking unit! the whole thing with batteries and gas has to be around 500 pounds! it has a 16 horse opposed twin onan.
my personal favorite for pipe work is 6011, flat work is 6013. and 7018 for vertical or overhead projects.
it sure is a fun unit to tinker with, it has a rough and fine control for amperage and a built in 3kw generator to boot!
you call them ferrets, i call them weasels.
