K3136-1 - Lincoln Magnum PRO 550 Dual Schedule MIG Gun, 10ft, 550A

Unmatched Endurance for Heavy Industry

The Lincoln Electric Magnum® PRO 550 Dual Schedule Welding Gun (K3136-1) is engineered for the most demanding industrial environments. Rated at 550 amps at 100% duty cycle with CO2 shielding gas, this air-cooled semiautomatic gun delivers continuous welding performance without compromising on durability. It is specifically designed for high-amperage applications in shipbuilding, heavy equipment manufacturing, and structural construction where downtime is not an option.

This model features Lincoln's Dual Schedule technology, allowing the welder to switch between two distinct welding procedures directly from the gun trigger. This capability significantly enhances efficiency when working on complex assemblies requiring different parameters for different joints, eliminating the need to return to the power source to adjust settings.

The Magnum PRO 550 utilizes Lincoln's premium Copper Plus® contact tips. These tips possess a larger diameter and greater mass compared to standard tips, resulting in superior heat dissipation and extended consumable life. The gun also incorporates a patent-pending Anti-Seize tip and diffuser thread design, ensuring that consumables remain easy to remove and replace even after prolonged high-heat operation. The Secure-Lock gun tube design prevents rotational slipping, maintaining precise orientation during long welds.
