The Elektron MultiMig MIG/MAG inverter welders, Nos. 511 and 522, are designed to help technicians weld aluminum as easily as they weld steel. Both welders are included in the Ford 2015 F-150 Collision Repair Program and can be used with a standard MIG torch. These welders can weld and braze aluminum alloys, galvanized sheet metal, stainless steel and high-strength steel. The welders have high-duty cycles and the power required for most body shop applications using up to 1.2mm welding wire, as well as the push-pull torch style that’s essential for smooth aluminum wire feed. The MultiMig 511 and 522 can reduce burn-through on very thin aluminum, but provide full penetration on thicker aluminum sheets.
