OVERVIEW

Maximize Productivity with the Lincoln Magnum PRO 350 Dual Procedure Gun

Take control of your welding operations with the Lincoln Electric Magnum® PRO 350 Dual Procedure Welding Gun. Designed for professional welders who demand reliability and versatility, this 350-amp MIG gun is built to handle the toughest jobs without backing down. Whether you are working on heavy equipment repair, structural steel, or general fabrication, the K3131-1 delivers the power and endurance you need to keep the arc lit.

The standout feature of this gun is its Dual Procedure capability. Imagine being able to switch between a high-heat setting for flat welds and a lower setting for vertical-up passes without ever leaving your workpiece. With the integrated rocker switch on the gun handle, you can toggle between two pre-set procedures instantly. This saves time, reduces movement, and keeps your focus where it belongs—on the puddle.

Built for Comfort and Endurance

Welding all day can be exhausting, but the Magnum PRO 350 is designed to help. The Comfort Grip™ handle is ergonomically shaped to fit naturally in your hand, reducing strain and fatigue. The gun is also perfectly balanced, making it easier to maneuver in tight spaces or out-of-position welds. Despite its comfort, it is incredibly tough. The 100% duty cycle rating at 350 amps means this gun won't overheat when you are pushing it to the limit.

Superior Consumables

Stop wasting time changing contact tips constantly. This gun uses Lincoln's premium Copper Plus® contact tips, which are designed with more mass to dissipate heat faster. This means they last longer and perform better, saving you money on consumables and reducing downtime. The Anti-Seize threads on the tips and diffusers also mean you won't be fighting to remove worn parts. Upgrade your welding setup with the Magnum PRO 350 and experience the difference that professional-grade equipment makes.
