K479-4 - Lincoln Magnum 400 MIG Gun, 15ft, Fast-Mate, .052-1/16 Wire

Power and Comfort with the Lincoln Magnum 400

When your welding projects demand high amperage and extended arc time, the Lincoln Electric Magnum 400 MIG Gun is the tool you can trust. Built to handle the heat, this 400-amp gun is a workhorse for professional welders tackling heavy fabrication, structural steel, or flux-cored applications. The K479-4 model comes ready to work with a generous 15-foot cable, giving you the freedom to move around large assemblies without constantly repositioning your wire feeder.

Designed for the Welder
Lincoln Electric understands that operator comfort is key to weld quality. The Magnum 400 features the classic curved handle that welders have relied on for years. It is lightweight and balanced to provide a sure, confident grip that significantly reduces hand fatigue during long shifts. The rotatable gooseneck is a game-changer for tight spaces, allowing you to position the nozzle exactly where you need it while keeping your wrist in a comfortable position.

Built to Last
Industrial environments are tough on equipment, but the Magnum 400 is tougher. The cable is encased in a rugged, abrasion-resistant rubber jacket that resists cuts and wear from rough surfaces. The gun tube itself is armored and insulated, protecting the internal components from impact and radiant heat. With a high-quality modular trigger designed to resist spatter buildup, this gun delivers reliable starts every time. This specific configuration features the Fast-Mate connection and is set up for heavier wires (.052 - 1/16 inch), making it the perfect upgrade for your heavy-duty welding operations.
