K3135-1 - Lincoln Magnum PRO 550 Dual Procedure MIG Gun, 10ft, 550A Air-Cooled

Heavy-Duty Industrial Performance

The Lincoln Electric Magnum PRO 550 Dual Procedure Welding Gun (K3135-1) is engineered for the most demanding industrial environments. Designed for high-amperage applications, this air-cooled gun delivers a massive 550 amps at 100% duty cycle when using CO2 shielding gas, and 375 amps at 100% duty cycle with mixed gases. It is the ideal solution for heavy fabrication, shipbuilding, and construction where equipment downtime is not an option. The 10-foot cable length provides a standard reach for stationary bench work or wire feeders mounted on booms.

Dual Procedure Control

Efficiency is key in production welding. The "Dual Procedure" feature of the K3135-1 sets it apart from standard guns. Equipped with an integrated switch and four trigger leads, this gun allows the operator to toggle between two different welding procedures (such as voltage or wire feed speed settings) directly from the handle. This eliminates the need to walk back to the wire feeder to adjust settings when changing positions or joint configurations, significantly streamlining workflow.

Superior Consumable Life

Lincoln Electric has integrated their premium Copper Plus® contact tip technology into the Magnum PRO series. These tips possess a larger diameter and greater mass than standard tips, improving heat dissipation and extending tip life. Coupled with the patent-pending Anti-Seize™ tip and diffuser thread design, the K3135-1 minimizes the common issue of parts fusing together due to heat, ensuring that maintenance is quick and frustration-free.

Built for the Operator

Despite its heavy-duty rating, the Magnum PRO 550 prioritizes operator comfort. The Comfort Grip™ handle utilizes a barrel-style design that is lightweight and balanced, reducing hand fatigue during long shifts. The Secure-Lock™ gun tube resists rotational slipping, providing a stable and predictable feel regardless of the welding angle. From its aircraft-grade aluminum components to its rugged outer jacket, every aspect of this gun is built to withstand the rigors of the shop floor while keeping the welder comfortable.
