That's the same outfit I have, paid $270 for it about 4 years ago. There are no gauges for it, supposedly the regulator is plug-n-play. Don't know, I've only used flux-cored wire so far. Works ok for everything I've done. It's rated to weld up to 1/8" steel but I've done 3/16" single-sided by cranking up the wire speed and making a slow pass. Also have welded 1/4" when I could get to both sides.
Come on. New job doesnt start for a couple weeks. Would help my awesome idea of building an on road pump trolley/ hand car.
