The Lincoln Electric Magnum PRO Curve 300 AL Push Gun (K4700-1-10-116A) represents a targeted engineering solution for the unique challenges of aluminum MIG welding. Unlike standard steel MIG guns, feeding soft aluminum wire requires a specialized approach to prevent buckling and bird-nesting. This 10-foot push gun is meticulously designed with a rigid liner system and optimized geometry to support 3/64" and 1/16" aluminum wires, ensuring smooth, consistent delivery from the feeder to the contact tip. It serves as an ideal, cost-effective alternative to complex push-pull systems for applications where a 10-foot reach is sufficient.
Built on Lincoln's renowned Curve platform, this gun prioritizes operator comfort. The lightweight handle is balanced to reduce wrist strain and fatigue during extended welding sessions, while the rotating gun tube allows welders to adjust the torch angle for optimal access to joints. The construction is rugged enough for industrial environments, yet sensitive enough to handle delicate aluminum operations. The integration of the K466-10 backend connector ensures seamless compatibility with Lincoln Electric wire feeders, providing a secure and conductive connection that maintains arc stability.
A key differentiator for the Magnum PRO Curve 300 AL is its utilization of Magnum PRO expendables. These high-performance consumables are designed to maximize uptime and reduce operational costs. The included Copper Plus contact tips feature a larger mass and superior heat dissipation properties compared to standard tips, resisting fusion and extending life even under the high thermal conductivity conditions of aluminum welding. The patented anti-seize tip and diffuser thread design prevents parts from fusing together, making changeovers quick and tool-free. This package comes ready to weld with a complete set of insulators, diffusers, nozzles, and tips specifically selected for aluminum applications.
Rated for 300 Amps at 60% duty cycle using CO2 (or 225A at 80% with Argon), this air-cooled gun delivers the power necessary for structural aluminum fabrication, automotive repair, and general manufacturing. The 10-foot cable length strikes the perfect balance between reach and feedability, minimizing the friction that typically plagues longer push-only aluminum setups. Whether you are welding thin gauge sheet or heavier plate, the Magnum PRO Curve 300 AL provides the control and reliability professional welders demand.
