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.
