KP1909-1 - Lincoln Electric KP1909-1 Magnum Gun Tube Gooseneck 62 Degree

Genuine Lincoln Electric Replacement Gun Tube

The Lincoln Electric KP1909-1 is a premium Gun Tube Assembly designed to restore the functionality and performance of compatible Lincoln MIG welding guns. As a critical component in the welding torch assembly, the gun tube—often referred to as the gooseneck—serves as the conduit for the welding wire, shielding gas, and welding current. Over time, gun tubes can become damaged due to heat stress, accidental impacts, or thread wear, leading to poor conductivity and erratic wire feeding. This genuine Lincoln Electric replacement part ensures that your equipment operates at the high standards required for industrial fabrication.

Optimized 62-Degree Geometry

This specific assembly features a 62-degree bend angle. The geometry of a MIG gun neck is crucial for welder ergonomics and joint accessibility. A 62-degree angle provides a comfortable hand position for a wide variety of welding applications, allowing the operator to maintain a neutral wrist posture while accessing fillet welds and other common joint configurations. By using the correct angle specified for the gun, users ensure that the liner feeds smoothly through the bend, reducing friction and preventing wire shaving or bird-nesting issues that can occur with improper or generic replacements.

Durability and Performance

Constructed from high-quality conductive materials and robust insulation, the KP1909-1 is built to withstand the thermal cycling and mechanical abuse typical of heavy-duty welding environments. The assembly is engineered to maintain a consistent gas flow path, ensuring that the weld pool is adequately shielded from atmospheric contamination. It integrates seamlessly with Lincoln's consumable systems, providing a secure mounting point for gas diffusers and nozzles. For maintenance and repair operations (MRO) and fabrication shops relying on Lincoln Electric equipment, stocking genuine replacement tubes like the KP1909-1 minimizes downtime and maintains the integrity of the welding system.
