K2286-1 - Lincoln Magnum 400 MIG Gun, 400A, 15ft, .035-.045 Wire, K2286-1

Industrial Grade 400A MIG Welding Gun

The Lincoln Electric Magnum 400 Welding Gun Package (K2286-1) is a robust semi-automatic MIG gun designed for high-amperage applications in heavy industrial environments. Engineered for durability and performance, this air-cooled gun is rated at 400 amps with a 60% duty cycle when using CO2 shielding gas. It comes pre-configured with a 15-foot (4.5 meter) cable assembly, providing ample reach for large fabrication projects and structural steel work. The package specifically includes the K466-1 Gun Connector Kit, ensuring immediate compatibility with popular Lincoln Electric wire feeders such as the LN-7, LN-8, LN-9, and the widely used LN-25 series.

Technically, the Magnum 400 is built to handle wire diameters ranging from 0.035 to 0.045 inches (0.9-1.2 mm) right out of the box, making it versatile for both solid MIG wire and gas-shielded flux-cored wires. The gun features a 60-degree gooseneck tube which is rotatable, allowing the operator to adjust the angle for optimal access to complex joints without straining the cable. The internal construction utilizes a high copper strand count cable, which ensures efficient conductivity and flexibility, while the outer jacket is made from abrasion-resistant extruded rubber to withstand the rigors of shop floors and construction sites.

Maintenance and serviceability are key features of the K2286-1. It utilizes a one-piece modular trigger assembly molded from high-heat resistant material, designed to resist spatter and ensure positive electrical contact over a long service life. The gun tube is armored with an electrically insulated metal jacket, optimizing fine wire welding performance. This unit is an ideal replacement or upgrade for welders requiring a reliable 400-amp torch that integrates seamlessly with existing Lincoln Electric feeder setups.
