OVERVIEW

Maximize Comfort and Performance with the Magnum PRO Curve 400

Welding is a demanding job, and the tools you use can make the difference between a long, tiring day and a productive one. The Lincoln Electric Magnum PRO Curve 400 MIG Gun (K2952-3-3-45) is designed with the welder in mind, combining industrial-grade power with superior ergonomics. With a 20-foot cable reach, this gun gives you the freedom to move around large assemblies without constantly repositioning your feeder.

Built for the Long Haul

Stop wasting time changing contact tips. The Magnum PRO Curve 400 utilizes Lincoln's exclusive Copper Plus contact tips. These tips are built with more copper and a larger diameter to disperse heat faster than the competition. The result? Your tips last longer, your arc stays stable, and you spend more time welding and less time swapping out parts. The Anti-Seize threads on the diffuser and tip mean that when it is finally time to change them, they won't be frozen in place.

Ergonomics That Make Sense

The "Curve" handle isn't just a name—it's a solution to operator fatigue. The handle is sculpted to fit naturally in your hand, providing a secure grip that doesn't require excessive squeezing. It is lightweight and perfectly balanced to reduce strain on your wrist and forearm. Need to weld in a tight corner or overhead? The gun tube rotates 360 degrees, allowing you to position the nozzle exactly where you need it while keeping your hand in a comfortable position.

Ready to Weld

This Ready-Pak comes fully assembled with a K466-3 connector, liner, and consumables, so you can hook it up and start laying beads immediately. Whether you are working in heavy equipment manufacturing, structural steel, or general fabrication, the Magnum PRO Curve 400 delivers the 400-amp punch you need with the comfort you deserve.
