K471-21 - Lincoln Magnum 400 MIG Gun Package, 15ft, .035-.045 Wire

Heavy-Duty Performance with the Magnum 400

Step up your welding game with the Lincoln Electric Magnum 400 MIG Gun, a tool built to handle the heat of high-amperage applications without sacrificing operator comfort. When your projects demand 400 amps of power, you need a gun that won't overheat or weigh you down. The Magnum 400 features Lincoln's classic curved handle design, which is lightweight and balanced to sit naturally in your hand. This ergonomic focus helps reduce wrist strain and fatigue during long shifts, allowing you to maintain precision and control from the first bead to the last.

Durability is at the core of the Magnum 400's design. The 15-foot cable is protected by a tough, abrasion-resistant rubber jacket that stands up to the rough-and-tumble reality of welding shops. Whether it's being dragged over concrete, around steel corners, or exposed to sparks, this gun is constructed to last. The gooseneck is armored and insulated, reflecting radiant heat away from the gun tube and further protecting the internal components. For welders who deal with flux-cored or MIG processes daily, the reliable feeding and rugged construction of the Magnum 400 make it an indispensable asset.

This package (K471-21) arrives ready to work, equipped with a liner for .035 to .045 wire and a standard Lincoln connector. The rotatable tube design is a favorite among professionals, giving you the flexibility to adjust the gun angle for tight spaces or awkward joints without contorting your body. With high-quality copper cabling for efficient power delivery and a trigger designed to withstand spatter and heat, the Magnum 400 is the reliable partner you need for heavy fabrication, structural steel, and equipment maintenance.
