KP2455-1 - Lincoln Electric 45-Degree MIG Gun Gooseneck Assembly, 6 Inch

Product Overview

The Lincoln Electric KP2455-1 is a specialized Gun Tube Assembly designed to serve as a direct replacement component for compatible Lincoln Electric MIG welding guns. This assembly features a precise 45-degree bend and a total length of 6 inches, dimensions that are critical for maintaining the ergonomic profile and reach of the welding torch. As a genuine OEM part, it is engineered to meet the strict manufacturing tolerances required for industrial welding applications, ensuring seamless integration with existing gun handle assemblies and consumables.

Technical Functionality

In a MIG welding system, the gun tube (often referred to as the gooseneck or swan neck) plays a pivotal role in the delivery of welding current, shielding gas, and electrode wire. The KP2455-1 is constructed to facilitate the smooth transfer of the wire liner through the bend, minimizing friction and preventing wire feeding issues such as bird-nesting or erratic arc starts. The tube's material is selected for its electrical conductivity and heat resistance, allowing it to withstand the thermal cycles inherent in continuous welding operations without deforming or degrading.

Maintenance and Compatibility

Over time, gun tubes can become damaged due to accidental drops, excessive spatter buildup, or thread wear from frequent contact tip changes. Replacing a compromised tube with the KP2455-1 restores the structural integrity of the torch front-end. This assembly ensures that the gas diffuser and nozzle seat correctly, which is essential for maintaining laminar gas flow and preventing weld porosity. Industrial MRO procurement specialists should verify the specific gun model compatibility to ensure this 45-degree, 6-inch configuration matches the operator's requirements.

Operational Benefits

Using genuine Lincoln Electric parts like the KP2455-1 reduces downtime associated with component failure. The standardized 45-degree angle is the industry norm for general fabrication, offering a balance between comfort and accessibility. By maintaining the correct geometry of the torch, operators can execute welds with greater precision and less fatigue. This component is supplied as a single unit, ready for immediate installation into the gun handle.
