K2952-2-3-45 - Lincoln Magnum PRO Curve 400 MIG Gun for Miller Welders - 15ft

Maximize Comfort and Uptime with Lincoln Magnum PRO

Upgrade your welding setup with the Lincoln Electric Magnum® PRO Curve™ 400 Welding Gun, specifically configured in this Ready-Pak® (K2952-2-3-45) for direct compatibility with Miller® welding machines. This 15-foot air-cooled gun combines Lincoln's industry-leading consumable technology with a handle design focused entirely on operator comfort. Rated at 400 amps (60% duty cycle with CO2), it provides the power needed for high-deposition MIG and flux-cored welding applications while keeping the welder comfortable and productive.

The Curve™ Handle Difference

Welding fatigue is a real productivity killer. The Magnum PRO Curve handle addresses this with a slim, curved profile that sits securely in the palm, reducing the grip force required to maneuver the gun. The handle is lightweight and balanced, and the trigger leads are designed for longevity with four leads standard for fast field repair if necessary. For added versatility, the gun features a rotating tube and a convenient gun hanger clip, ensuring the tool is always ready for the next weld, regardless of the position or angle required.

Superior Consumable Life

Stop wasting time changing contact tips. The Magnum PRO Curve 400 uses Lincoln's premium Magnum PRO expendables. The Copper Plus® contact tips are engineered with more mass to draw heat away from the arc zone, keeping the tip cooler and extending its service life well beyond standard industry tips. The simplified expendable parts selection means that 350A and 550A consumables are interchangeable across the gun models, reducing inventory headaches for shops with mixed equipment. The thread-on gas nozzles and diffusers feature an anti-seize design that resists spatter buildup and thread damage.

Seamless Integration

This gun is built to bridge the gap between brands. If your shop runs Miller power sources, you don't have to settle for stock guns. The K2952-2-3-45 includes the K466-3 Gun Connector, allowing you to plug directly into the front of your Miller feeder. It comes ready to weld with .045" wire, including a liner, contact tip, and nozzle, so you can get back to work immediately. Whether you are welding mild steel, stainless, or flux-cored applications, this gun delivers consistent feeding and arc stability.
