I'd go along with what Putt Putt said, about the smaller torches used for aircraft steel. (I personally use TIG, but that's a different story)
Also, I'd add a flashback arrester if it doesn't come with one. Also, very important to learn how to SAFELY turn your rig on and off, adjust it and bleed it down when finished. - very important. Torches can be dangerous if not used properly.
