OVERVIEW

Maximize Efficiency with the Magnum PRO 350

Take control of your welding projects with the Lincoln Electric Magnum® PRO 350 Dual Procedure Welding Gun. This 25-foot MIG gun is built for professional welders who demand reliability and comfort. The standout feature is the Dual Procedure switch located right on the handle, which lets you flip between two pre-set welding modes instantly. whether you are moving from a flat weld to a vertical one, or dealing with varying joint fit-ups, you can adjust your arc without ever walking back to the machine. This saves time and keeps you in the zone.

Comfort is key when you are welding all day, and the Magnum PRO 350 delivers with its Comfort Grip™ design. The barrel-style handle is lightweight and perfectly balanced to reduce hand fatigue, no matter how you hold the gun. Inside, the industrial-grade construction features high-quality copper and aircraft-grade aluminum parts that ensure excellent electrical conductivity and heat management. You can run this gun at 350 amps (with CO2) all day long thanks to its 100% duty cycle rating.

Consumable life is another major benefit. This gun uses Lincoln's Copper Plus® contact tips, which are beefier than standard tips to handle more heat and last longer. The Anti-Seize threads on the diffuser and tip mean you won't be fighting to change parts when they get hot. The package comes ready to weld with a standard contact tip, gas nozzle, and diffuser included. If you are looking for a rugged, high-performance MIG gun that adapts to your workflow, the K3131-4 is the tool for the job.
