This machine can do DC TIG, mig and stick. I used it manly for TIG welding but since bought a better one. Maybe 10 pounds of wire has been welded through it. Does mig pulse as well. Can add an aluminum spool gun or aluminum push pull gun as accessories. Includes a small air cooled TIG torch, 030,035, 045 drive rolls. A bunch of tips, spare liner, and small 75/25 mix argon cylinder
