OVERVIEW

Maximize Productivity with Magnum PRO

Upgrade your welding setup with the Lincoln Electric K3135-1 Magnum PRO 550 Dual Procedure Welding Gun. This 10-foot semiautomatic MIG gun is designed for professional welders who demand reliability and versatility. Capable of handling wire diameters from 0.035" up to 1/8", it is a powerhouse for MIG, Pulsed MIG, and Flux-Cored processes. The gun is rated for continuous operation at 550 amps (CO2), ensuring it stays cool even under the most intense welding schedules.

Advanced Dual Procedure Technology

The K3135-1 features Lincoln's Dual Procedure capability, a game-changer for complex fabrications. A convenient switch located on the gun handle communicates with compatible wire feeders to instantly swap between two pre-set welding modes. Whether you need a hot pass for penetration and a cooler pass for the cap, or different settings for vertical vs. flat welds, you can control it all without leaving the arc zone.

Innovative Design Features

  • Copper Plus® Tips: Engineered with more copper to pull heat away from the wire, preventing burn-back and extending the life of your consumables.
  • Anti-Seize™ Threads: The diffuser and tip threads are designed to prevent seizing, making consumable changes fast and tool-free in many cases.
  • Secure-Lock™ Tube: A robust locking mechanism ensures the gun tube stays exactly where you position it, eliminating the annoyance of a loose or rotating neck.

Comfort and Durability Combined

Welding at 550 amps typically requires bulky, heavy equipment, but the Magnum PRO 550 defies this trend with its Comfort Grip™ design. The handle is ergonomically shaped to fit naturally in the hand, distributing weight evenly to minimize strain on the wrist and forearm. The industrial-grade construction features high-quality copper parts for optimal electrical conductivity and aircraft-grade aluminum for structural integrity without excess weight. Choose the K3135-1 for a welding gun that works as hard as you do.
