KP1928-1 - Lincoln Magnum 400 Gooseneck Assembly 60 Degree

Product Overview

The Lincoln Electric KP1928-1 is a premium Gun Tube Assembly designed to serve as a direct replacement component for the widely used Magnum® 200 and Magnum® 400 MIG gun series. This assembly, often referred to as a gooseneck or conductor tube, is a critical element in the MIG welding torch system, responsible for guiding the welding wire and shielding gas from the handle to the contact tip while conducting the welding current. The KP1928-1 features a standard 60-degree bend, which is the most common configuration for general fabrication, offering a balance between reach and ergonomic comfort for the operator.

Engineered to meet Lincoln Electric's rigorous industrial standards, this tube assembly is rated for 400 Amps, making it suitable for heavy-duty welding cycles often found in structural steel, heavy equipment manufacturing, and general fabrication environments. The robust construction ensures that the tube can withstand the thermal stresses associated with high-amperage welding without deforming or losing conductivity. As an OEM part, it guarantees precise thread alignment with the gun handle and the gas diffuser, ensuring a leak-free gas path and optimal electrical contact.

Maintaining the integrity of the gun tube is essential for weld quality. A damaged or worn tube can lead to wire feeding issues, erratic arcs due to poor conductivity, or gas coverage problems resulting in porosity. The KP1928-1 is designed for easy installation, allowing maintenance personnel or operators to quickly swap out damaged necks and minimize downtime. It is compatible with standard Magnum consumables, ensuring that existing contact tips, nozzles, and diffusers will fit perfectly.

This component is specifically identified by the internal SKU KP1928-1 and is distinct from other angles (such as 45-degree) or amperage ratings. It is supplied as a single unit. When servicing Lincoln Magnum guns, utilizing genuine Lincoln Electric parts like the KP1928-1 ensures that the equipment continues to operate within its specified safety and performance parameters.
