K471-14 - Lincoln Magnum 400 Semiautomatic MIG Gun, 25 ft, .052-1/16 in

Classic Comfort Meets High-Amperage Power

When the heat is on and the amperage is high, operator comfort becomes a critical factor in maintaining weld quality. The Lincoln Electric Magnum 400 Welding Gun (K471-14) addresses this need with its classic curved handle design. Known throughout the industry for its ergonomic balance, this handle fits naturally in the hand, providing a sure, confident grip that significantly reduces operator fatigue during long welding sessions. Whether you are running long beads on heavy plate or maneuvering through complex assemblies, the Magnum 400 is designed to keep you welding comfortably.

This 25-foot model offers the freedom of movement essential for large-scale projects. No longer tethered closely to your power source, you can access distant joints with ease. The gun is rated for 400 amps at a 60% duty cycle, making it a powerhouse for most .045 to 1/16 inch gas-shielded operations. It is particularly effective for applications utilizing UltraCore or Metalshield wires, delivering smooth feeding and consistent arc characteristics. The rugged strain relief system protects the cable liner and prevents acute cable angles, ensuring that wire feeds smoothly from the spool to the contact tip without binding.

Durability is built into every component of the K471-14. The one-piece trigger assembly is designed to withstand the harsh reality of welding spatter and high heat, ensuring long life and clean electrical signals. The extruded rubber jacket on the cable adds a layer of toughness that resists cuts and abrasion from dragging across concrete floors or around sharp metal edges. Compatible with a wide range of standard Lincoln Electric consumables, including contact tips, nozzles, and diffusers, the Magnum 400 is a reliable workhorse that integrates seamlessly into your existing Lincoln welding setup. Choose the Magnum 400 for a blend of traditional comfort and modern industrial toughness.
