I've been playing more with the new machine. I'm finishing a 40' aluminum boat trailer and had to do some steel on the hitch. This thing runs LO-HI better than any machine I have. Only 3/32" but man, what beautiful stable arc. More tweaking with AL and again, I'm impressed. Maybe counter intuitive, but .047" works the best for me. That could be because that it is my main wire and has been my whole career, a leftover from the guy I learned from. I am really, really happy. The only thing left is to really put it though some duty other than 12" tests. I can't wait to show up somewhere and be 'laughed at'! What is so cool is that the internal DC power supply runs the gun so well. I'm curious as to why the output is not 24V as Mark implied but I think my time to be answered by the Everlast guys has expired. With the 30A there is a whole bunch of monkey-motion between the pot on the gun and the power at the welder or feeder that, frankly I would never be able to figure out how to configure. The 30A has seven wires to the gun. Now, only four do the job at the expense of not having wire speed control at the gun.
The unanswered Everlast guy question again is can I fry this thing and not know it? That is my only remaining concern.
