OVERVIEW

Heavy-Duty Magnum PRO 550 MIG Gun

Tackle the toughest welding jobs with the Lincoln Electric Magnum PRO 550 Dual Procedure Welding Gun. This 15-foot semi-automatic MIG gun is built to withstand the rigors of extreme environments, making it the ideal choice for industries such as heavy equipment manufacturing, structural steel, and shipbuilding. With a massive 550-amp rating at 100% duty cycle (using CO2), this gun delivers consistent, high-power performance without overheating, ensuring your production lines keep moving. The air-cooled design simplifies setup while maintaining the thermal capacity needed for flux-cored and pulsed MIG processes.

Dual Procedure Efficiency

Maximize your productivity with the integrated Dual Procedure control. This feature allows welders to switch between two different welding procedures instantly using a switch located on the gun handle. Whether you need to change wire feed speeds or voltage settings for different material thicknesses or positions, the K3135-2 puts control right at your fingertips, eliminating unnecessary trips back to the power source. This seamless transition capability is a game-changer for complex fabrication tasks.

Built for the Welder

Lincoln Electric understands that comfort equals productivity. The Magnum PRO 550 features the signature Comfort Grip design, a lightweight, balanced handle that fits naturally in the hand to reduce fatigue. The gun is also designed for easy maintenance; the PRO Select Gun Selection System ensures you have the right tool for the amperage, while the Anti-Seize tip and diffuser threads prevent parts from fusing together. The included Copper Plus contact tips offer superior heat dissipation, lasting longer than standard tips and saving you money on consumables over time. Upgrade to the Magnum PRO 550 for a welding gun that works as hard as you do.

FAQ

The Magnum PRO 550 is rated at 100% duty cycle at 550 Amps when using CO2 gas, and 100% duty cycle at 375 Amps when using mixed gas.

Dual Procedure means the gun has a switch that allows the operator to toggle between two different welding schedules (such as voltage and wire feed speed) set on a compatible wire feeder, without stopping to adjust the machine manually.

This gun is compatible with wire diameters ranging from 0.035 inches up to 1/8 inch (0.125 inches).

The K3135-2 Magnum PRO 550 is an air-cooled MIG gun.

Copper Plus contact tips have a larger diameter and greater mass than standard tips, which improves heat dissipation and extends the life of the tip in high-amperage applications.
