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.
MIG can be used automatically or semiautomatically. An example of automatic MIG is a robotic arm welding car frames at an auto assembly plant. Semiautomatic is when an operator holds the MIG gun and manipulates the weld pool. In automatic MIG, an operator sets up and watches the machine. An experienced welder is the preferred operator, because he has the right touchand knows what it means to be in the welding zone.
