K4700-1-6-116A - Lincoln Magnum PRO Curve 300 Aluminum MIG Gun, 10ft, Lincoln Rear

Reliable Aluminum Welding with the Magnum PRO Curve 300 AL

The Lincoln Electric Magnum PRO Curve 300 AL Push Gun (K4700-1-6-116A) represents a specialized solution for fabricators who need to weld aluminum wire without the expense or bulk of a spool gun. Designed specifically for short-distance applications, this 10-foot air-cooled MIG gun addresses the common challenges associated with feeding soft aluminum wires. By utilizing a highly rigid liner and optimized internal geometry, the gun minimizes friction and prevents the wire from buckling or "birdnesting" inside the cable, ensuring a smooth and consistent arc.

At the heart of this system is Lincoln's renowned Magnum PRO consumable platform. The gun comes standard with Copper Plus contact tips, which feature a larger diameter and greater mass than standard tips. This design improves heat dissipation and keeps the tip cooler, significantly extending the life of your expendables and reducing downtime for tip changes. The Anti-Seize threads on the contact tips and diffusers further prevent the components from fusing together, making maintenance quick and hassle-free in industrial environments.

Operator comfort is paramount in the design of the Curve handle. Lightweight and balanced, the handle fits naturally in the hand, reducing grip force requirements and minimizing fatigue during long welding sessions. The gun is rated for 225 amps at 80% duty cycle using Argon gas, making it robust enough for production aluminum work. This package includes the K466-6 connector kit, making it ready to connect directly to compatible Lincoln Electric wire feeders right out of the box. For shops looking for a dedicated, cost-effective aluminum solution, the Magnum PRO Curve 300 AL is the ideal choice.
