Using Miller Pipe Worx 400 to practice for a weld test. This is the most expensive machine I have used. 3/8 inch plate with 37.5 angle bevel, 1/8 root opening, 1/16 landing. Mig root downhill. Dual shield flux core up hill. If click the trigger on any of the two guns the machine will automatically switch over with the saved settings. Crazy expensive
