Lincoln Magnum PRO Curve 400 MIG Gun Ready-Pak (K2952-2-10-45)

The Lincoln Electric Magnum PRO Curve 400 is a premium semi-automatic air-cooled MIG welding gun designed for high-performance fabrication environments. Rated at 400 amps with a 60% duty cycle using CO2 shielding gas, this gun is engineered to handle demanding industrial applications including MIG (GMAW), Pulsed MIG (GMAW-P), and Flux-Cored (FCAW) welding. The K2952-2-10-45 Ready-Pak configuration comes pre-assembled with a 15-foot cable and is set up for .045" (1.2 mm) wire, making it an immediate replacement solution for compatible Lincoln power sources such as the Flextec 500X, Flextec 650X, and Power Wave S500.

At the core of the Magnum PRO series is the focus on consumable longevity and electrical efficiency. The gun utilizes Lincoln's Copper Plus contact tips, which feature a larger diameter and greater mass than standard tips. This design improves heat dissipation, preventing the tip from overheating and expanding, which is a common cause of wire burn-back and premature failure. Additionally, the patent-pending Anti-Seize thread design on the contact tips and diffusers ensures that consumables can be removed easily even after long periods of high-heat operation.

The "Curve" designation refers to the ergonomic handle design, which is lightweight and balanced to reduce operator fatigue during long shifts. The gun tube is rotatable 360 degrees without tools, allowing the welder to adjust the angle of the neck to access tight joints or maintain a comfortable hand position. Maintenance is simplified with a single expendable parts platform; 350A and 550A consumables are interchangeable across the entire Magnum PRO line, reducing inventory complexity. The gun also features four trigger leads for redundancy and fast field repairs.
