KP1929-1 - Lincoln Electric Magnum 400 Gun Tube Assembly 45 Degree

Reliable Performance with Lincoln Electric KP1929-1

The Lincoln Electric KP1929-1 Gun Tube Assembly is a premium replacement component engineered specifically for the rigorous demands of industrial MIG welding. Designed to fit the widely used Magnum® 200 and Magnum® 400 series MIG guns, this gun tube—often referred to as a gooseneck or swan neck—restores the structural integrity and electrical efficiency of your welding torch. When your original gun tube becomes damaged due to excessive heat, impact, or wear, it can lead to poor wire feeding, inconsistent gas coverage, and unstable arcs. Installing a genuine Lincoln Electric replacement ensures your equipment operates at peak performance levels.

This assembly features a standard 45-degree bend, which provides excellent ergonomics for the welder. The angle allows for comfortable access to weld joints in various positions, reducing wrist strain during long welding sessions. Rated for 400 Amps, the KP1929-1 is built with high-quality materials that effectively manage the heat generated during high-amperage welding, preventing premature failure and ensuring a long service life. The robust insulation protects the operator and the equipment, maintaining safety standards on the shop floor.

Key Benefits for Industrial Welders

Replacing a worn gun tube does more than just fix a broken part; it revitalizes the entire feeding system of the torch. A straight and clean internal path provided by a new tube ensures the welding wire glides smoothly, reducing friction and bird-nesting issues at the feeder. Furthermore, the precise machining of the gas ports ensures laminar shielding gas flow, which is critical for producing porosity-free welds.
