100 % argon gas is usually the gas of choice but mixtures like 50/50 argon/helium can be helpful for welding thick sections.Make sure the polarity is connected properly. mig welding aluminum requires reverse polarity. Another way of saying reverse polarity is Direct current electrode positive or DCEP.
Pulsed MIG (MIG-P): A modified spray transfer process that produces no spatter, because the wire does not touch the weld puddle. Applications best suited for pulsed MIG are those currently using the short circuit transfer method for welding steel, 14 gauge (1.8 mm) and up. Pulsed TIG (TIG-P): A modified TIG process appropriate for welding thinner materials.
