K115-1 - Lincoln Magnum Classic K115-1 Innershield Gun 450A 10ft

Reliable Flux-Cored Welding with the Lincoln K115-1

For professional welders tackling structural fabrication and field erection, the Lincoln Electric Magnum Classic K115-1 Welding Gun is the tool of choice. This semiautomatic, air-cooled gun is specifically designed for the Flux-Cored Self-Shielded (FCAW-S) process, often referred to as Innershield welding. With a robust 450-amp rating at 60% duty cycle, it handles high-amperage applications with ease, ensuring deep penetration and high deposition rates without overheating.

The K115-1 is built to last. It features a tough, reinforced rubber jacket that resists the wear and tear of dragging across concrete, steel, and rough terrain. The 10-foot cable length provides ample reach for working around large assemblies without sacrificing wire feedability. The included 82-degree gun tube is ergonomically angled to reduce wrist strain during long welding shifts, though the system is modular and accepts other tube angles if your specific application requires it. A heavy-duty trigger switch ensures reliable operation, giving you confidence that the arc will strike every time you pull the trigger.

Versatility is a key strength of the Magnum Classic series. This gun is capable of running wire diameters from 3/32" up to .120", covering the most common sizes for structural steel work. It comes pre-packaged with severe duty contact tips and insulated guides for 7/64" and .120" wire, so you can get to work right away. The simplified design also makes maintenance easy; consumables and replacement parts are readily available and simple to swap out in the field. When your project demands a welding gun that is as tough as the steel you are joining, trust the Lincoln K115-1 to get the job done.
