OVERVIEW

Maximize Comfort and Efficiency with Dual Schedule Control

Welding is demanding work, and the tools you use should work as hard as you do while keeping you comfortable. The Lincoln Electric Magnum PRO 350 Dual Schedule Welding Gun (K3132-3) is built with the welder in mind, combining industrial power with ergonomic design. The standout feature for any professional is the Dual Schedule trigger. Imagine being 20 feet away from your feeder, welding a vertical-up joint, and then needing to switch to a flat weld with different parameters. Instead of stopping, unclipping, and walking back to your machine, you simply click the trigger switch. This seamless transition keeps you in the zone, keeps the arc on, and gets the job done faster.

Comfort is not an afterthought with the Magnum PRO 350. The gun features Lincoln's signature Comfort Grip design. The lightweight, balanced barrel-style handle fits naturally in your hand, reducing wrist strain and arm fatigue during long shifts. Whether you are holding the gun in a standard position or maneuvering into a tight corner, the balance remains superior. The 20-foot cable gives you the freedom to move around large weldments without constantly dragging the feeder or feeling tethered.

Performance-wise, this gun is a beast. It is rated for 350 amps at a 100% duty cycle with CO2, meaning it can handle high-heat applications all day long. It utilizes Lincoln's Copper Plus contact tips, which have a larger diameter and more mass than standard tips. This extra mass dissipates heat more effectively, keeping the tip cooler and extending its life—saving you money on consumables and time on tip changes. If you are looking for a MIG gun that offers professional-grade reliability, advanced control, and all-day comfort, the K3132-3 is the upgrade your shop needs.

Why Welders Choose the Magnum PRO 350

  • Dual Schedule Trigger: Switch settings instantly without leaving the weld joint.
  • Stay Cool: 100% duty cycle means the gun handles the heat, so you don't have to stop.
  • Longer Tip Life: Copper Plus tips last longer and resist seizing.
  • Ergonomic Fit: Designed to reduce fatigue, keeping your hand steady for the perfect bead.
