OVERVIEW

Maximize Comfort and Uptime with the Magnum® PRO Curve™ 400

Take your welding projects to the next level with the Lincoln Electric Magnum® PRO Curve™ 400 Welding Gun. Designed for welders who demand both power and comfort, this 400-amp MIG gun is a workhorse built to handle long hours of fabrication without wearing you down. The secret lies in the classic Curve™ handle, which fits naturally in your hand, providing a lightweight and balanced grip that significantly reduces fatigue. When you are welding all day, the difference in ergonomics means better focus and higher quality welds.

Stop wasting time and money on frequent contact tip changes. The Magnum® PRO Curve™ 400 utilizes Lincoln's exclusive Copper Plus® contact tips. These tips are designed with more mass to dissipate heat faster than standard tips, keeping them cooler and lasting longer. This means you spend more time burning wire and less time swapping out parts. The 20-foot cable length gives you the freedom to move around large workpieces without constantly dragging your feeder, while the rotating gun tube lets you hit those hard-to-reach angles with ease.

This Ready-Pak® comes fully assembled and ready to weld. It includes a K466-3 connector kit for seamless hookup to your Lincoln Electric wire feeder and is pre-configured for 0.045-inch wire. Whether you are running solid MIG wire or flux-cored wire, this gun delivers a stable arc and consistent feeding. The industrial-grade construction ensures it can take a beating in the shop and keep performing. Upgrade your setup today with a gun that works as hard as you do.
