Arc weld

A 30A spool gun is better than the 200 but also costs about $500/600 more. Push/pull you're looking at big bucks! 212 has more duty cycle than the 211, doesn't need a cart and allows you to use the large spools of MIG wire. Welding aluminum you'd really appreciate the higher duty cycle. The larger spools can save you a lot of money if you start doing more welding. The 212 also uses the M 25 gun which is the same as used on the 252. Trying to run aluminum through a standard MIG gun, even with a teflon liner, is just going to be an exercise in frustration. It's the exact reason they make spool guns.
