K3055-2 - Lincoln Magnum PRO Curve 400 Shortneck MIG Gun 15ft

Lincoln Magnum PRO Curve 400 Welding Gun - 15 ft Cable

Maximize your welding productivity with the Lincoln Electric Magnum PRO Curve 400 (K3055-2). This industrial-grade semi-automatic MIG gun is built to withstand the toughest shop environments while delivering reliable arc performance. Rated at 400 Amps with a 60% duty cycle, this gun is a workhorse for fabrication shops utilizing MIG, Pulsed MIG, or Flux-Cored processes. The 15-foot cable assembly offers the flexibility needed to move freely around large workpieces, ensuring you aren't tethered too closely to the power source.

Built for the Welder

The "Curve" in the name refers to the ergonomic handle design that sets this gun apart. Unlike blocky, straight handles, the Curve handle fits naturally in the palm, reducing grip force requirements and minimizing hand fatigue. This is crucial for welders operating at 400 amps where heat and weight can become factors. Additionally, the gun features a 360-degree rotating tube, allowing the operator to position the trigger and neck in the most comfortable orientation for the specific joint being welded. Whether you are welding overhead, vertical-up, or in a flat position, the K3055-2 adapts to you.

Superior Consumable Life

Stop wasting time changing contact tips. The Magnum PRO Curve 400 uses Lincoln's exclusive Copper Plus® contact tips. These tips feature a larger surface area for better electrical conductivity and heat transfer. By dissipating heat more effectively, the tips resist melting and keyholing, lasting significantly longer than standard industry tips. The gas nozzles and diffusers are also heavy-duty, featuring thread-on connections that stay tight during operation but release easily when it's time to swap them out, thanks to the anti-seize thread geometry.

Industrial Reliability

Every component of the K3055-2 is designed for longevity. From the abrasion-resistant cable jacket to the robust trigger mechanism, this gun is constructed to minimize repair costs and maximize uptime. The short neck design provides excellent control for standard welding tasks, while the compatibility with a wide range of wire diameters (0.025" - 5/64") makes it a versatile tool for any shop floor. Included in the box are the essential front-end parts to get you started immediately, including a standard contact tip, gas nozzle, and diffuser.
