OVERVIEW

Maximize Comfort and Productivity on the Shop Floor

Welding is a demanding job, and the equipment you hold in your hand for hours a day makes all the difference. The Lincoln Electric Magnum® PRO Curve™ 400 Welding Gun is built with the welder in mind, combining industrial-grade durability with superior comfort. If you are tackling heavy-duty projects that require 400 amps of power, this 20-foot MIG gun gives you the reach and reliability you need to keep the arc lit and production moving. It is the perfect upgrade or replacement for your heavy fabrication setup.

Built for the Long Haul

Downtime kills productivity, and constantly changing contact tips is a major culprit. The Magnum PRO Curve 400 utilizes Lincoln's exclusive Copper Plus® contact tips. These aren't your average tips; they are thicker and heavier, designed to pull heat away from the wire interface. This means they last longer, resist melting, and keep you welding instead of walking to the parts bin. Combined with the heavy-duty nozzle and diffuser system, this gun is ready to withstand the heat and spatter of high-amperage MIG and flux-cored welding.

Feel the Difference

The first thing you will notice is the handle. The Curve™ design isn't just for looks—it is engineered to reduce hand strain. It is lightweight and balanced perfectly, so you aren't fighting the weight of the cable all day. Whether you are welding flat, horizontal, or overhead, the rotating gun tube allows you to position your hand comfortably while maintaining the perfect torch angle. Plus, the integrated hanger clip keeps your gun off the floor and safe when you need a break.

Complete Ready-Pak

This K2952-3-6-45 package is a Ready-Pak, which means it arrives ready to work. It includes the necessary gun connector (K466-6) to hook up to your Lincoln feeder immediately. With 20 feet of cable, you have plenty of room to move around large weldments without dragging your machine.
