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.
In the nineteen sixties, as in 2014, all the weld research personnel had to do when MIG welding gage parts, was simply use a two part argon 2%CO2 gas mix (lower voltage than helium mixes) and an 0.035 wire, then change the MIG parameters to low spray transfer settings for parts > 3 mm.
