Its an auto welder, basically like a lathe where the job is grabbed by a chuck that spins really slow. I just set the torch up at the right angles and arc length, set the speed at which the chuck turns and adjust the volts and wire speed. It also has a sensor that makes the torch step over to start the next bead, you can kind of see where it does that at the bottom of the last pic.
Kind of cheating lol but its pretty difficult to do it all in one go without the shield filling with splatter (making the weld porus) or the wire welding itself to the tip and spattering like crazy. Plus the welder itself is pretty old and throws a tantrum at random intervals.
