K471-11 - Lincoln Magnum 400 Semiautomatic MIG Gun, 20ft, .052-1/16 Wire

Maximize Comfort and Productivity with the Magnum 400

Welders know that comfort equals productivity, especially when working with high amperages. The Lincoln Electric Magnum 400 Welding Gun (K471-11) features Lincoln's classic curved handle, a design favorite among professionals for its balance and ergonomic grip. By distributing weight effectively and providing a natural hand position, this gun significantly reduces operator fatigue during long shifts. Whether you are welding thick plate or fabricating heavy machinery, the Magnum 400 allows you to maintain focus and control, resulting in higher quality welds and less downtime.

Built for the Toughest Shop Environments

When the heat turns up, the Magnum 400 keeps performing. Rated for 400 amps, this air-cooled gun is designed to withstand the greater heat levels generated by higher amperage applications. It is the ideal tool for running .045 through 1/16 inch wires in gas-shielded operations. The industrial-grade construction includes a tough rubber jacket that resists cuts and abrasion, ensuring your equipment lasts longer even in harsh industrial settings. The gun tube is buffed to reflect radiant heat, keeping the front end cooler and protecting the consumables.

Reliable Feeding and Easy Operation

Wire feeding issues can stop a job in its tracks. The Magnum 400 utilizes an internal extruded tube design that offers excellent gas sealing integrity and smooth wire delivery. The 20-foot cable length gives you the freedom to move around large workpieces without constantly repositioning your feeder. Included with the gun are essential consumables—contact tip, gas diffuser, nozzle, and liner—so you are ready to weld right out of the box. Upgrade your welding setup with a gun that combines Lincoln Electric's legendary reliability with the heavy-duty performance required for professional results.
