Found this machine cheaper after purchase but I'm not mad! I love this shop! It would be nice to add gas if I wanted to, but I'm not tapping this welder at all. I've pulled over 20 rolls of 2# wire through and welded steel down to 3/4" (this requires some welding skills and knowledge of what you're doing as 3/4" penetration will not happen on a flat surface). to a flat project). I love this welder and would recommend it to both beginners and professionals.
