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.
Step 1: Background. MIG welding was developed in the 1940's and 60 years later the general principle is still very much the same. MIG welding uses an arc of electricity to create a short circuit between a continuously fed anode (+ the wire-fed welding gun) and a cathode ( - the metal being welded).
