MIG guns are an important part of GMAW or Gas Metal Arc Welding as they hold the welding wire that is fed through by the wire feeder, and also are fragile, feature parts that wear down and need to be replaced like the nozzles, tips, swirl rings, springs, and other parts of the MIG gun body. It is important to choose a reliable MIG welding gun. That is why LONGEVITY has partnered with two reputable MIG torch manufacturers Binzel and Trafimet. We offer parts for both companies and our equipment comes standard with Binzel MIG guns.
