OVERVIEW

Reliable Power for Tough Welding Jobs

When your welding projects demand high heat and serious power, the Lincoln Electric Magnum 400 Welding Gun (K471-15) delivers. Built to handle 400 amps at a 60% duty cycle, this gun is a workhorse for welders who need to lay down a lot of metal. Whether you are running flux-cored wire or solid MIG wire with gas shielding, the Magnum 400 is designed to keep you welding comfortably and efficiently. This model comes equipped with a 25-foot cable, giving you the freedom to move around large assemblies, trailers, or structural beams without constantly dragging your machine behind you.

Comfort That Lasts All Shift

Welding at 400 amps generates significant heat, and holding a heavy gun all day can take a toll on your hands and wrists. Lincoln Electric addresses this with their signature curved handle design. It fits naturally in the hand, providing excellent balance and reducing the strain associated with heavy-duty welding. The handle stays cooler and offers a secure grip, allowing you to focus on the puddle rather than the weight of the torch. The trigger is designed for durability and consistent response, ensuring you have precise control over the arc start and stop every time.

Built to Withstand the Shop Floor

Industrial environments are tough on equipment, but the Magnum 400 is tougher. The cable is encased in a thick, abrasion-resistant rubber jacket that resists cuts, scrapes, and hot sparks. The gun tube features an armored jacket that protects the neck from bangs and drops while insulating the electrical components. This durability translates to less downtime and fewer repairs. The K471-15 is set up right out of the box for 1/16" to 5/64" wire, making it perfect for heavy fabrication tasks. Plus, with a rotatable gooseneck, you can easily adjust the gun angle to get the perfect shot at difficult joints.

Key Benefits for the Welder

  • High Output: 400A rating handles thick materials with ease.
  • Extended Reach: 25-foot cable lets you work further from the power source.
