Lincoln Electric Magnum 450A FCAW-SS Welding Gun (K115-2)

The Lincoln Electric Magnum 450A FCAW-SS Welding Gun (K115-2) represents the industry standard for heavy-duty, self-shielded flux-cored arc welding. Engineered for durability and performance, this gun is designed to withstand the harsh environments typical of structural steel fabrication, shipbuilding, and heavy equipment repair. With a rating of 450 amps at a 60% duty cycle using CO2, it meets NEMA specification EW3, ensuring reliable power delivery for demanding welds.

One of the standout features of the K115-2 is its robust construction. The cable assembly is protected by a reinforced rubber jacket that resists cuts, abrasion, and heat, significantly extending the life of the equipment in rough field conditions. Despite its rugged build, the gun remains surprisingly lightweight and flexible, allowing welders to maneuver easily around complex structures without excessive fatigue. The heavy-duty trigger switch is built for positive electrical contact, reducing the risk of intermittent operation during critical passes.

This model comes equipped with a 15-foot cable and an 82-degree gun tube, providing excellent reach and access to joints. It is factory-ready to feed large diameter wires ranging from 7/64 inch to 0.120 inch, making it a powerhouse for high-deposition welding. The package includes severe duty contact tips and insulated guides, ensuring you have the necessary consumables to get started immediately. For professionals seeking a dependable tool for Innershield welding, the Lincoln Magnum 450A is a proven choice that delivers consistent results.
