Just set up this machine today and was welding 3 x 1 1/2 x 1/4 inch aluminum channel. The welder was real smooth and even. Tungsten was super stable at 330 amps and weld bead held smaller than on a syncrowave 350. Only reason I gave it a 4 star is the duty cycle could be a little better. Awesome welder. I have welded for over 30 years.
