The Lincoln Electric KP1929-2 is a 300-amp, 45-degree, air-cooled gun tube assembly, also known as a gooseneck or conductor tube, designed for Magnum 300 series MIG guns. It functions as the structural and electrical conduit between the gun handle and the welding consumables, featuring a high-purity copper core and a metallic armor jacket to manage thermal and electrical loads in industrial welding environments.
Features
High-purity copper core for electrical transfer to the contact tip
Metallic armor jacket for resistance to spatter, impact, and reflected heat
45-degree bend configuration for weld joint accessibility
Internal insulation for protection of electrically live components
Mechanical integration designed for Magnum 300 handles to prevent gas leaks
