ahp 200x and a cut50f. the tig needed a torch upgrade really bad. used a small ck that uses 2 series consumables, air cooled, gas lens kit made all the difference. its actually been great, very nice stable arc and the HF start is perfect. i dont auto pulse much but if i did id be bummed that it doesnt pulse very fast or very slow. the plasma is ok. certainly nothing amazing. it cut metal and doesnt take up much space.
