K470-1 - Lincoln Magnum 300 MIG Gun, 300A, 10 ft, .035-.045 Wire

Reliable Performance with the Lincoln Magnum 300 MIG Gun

For professional welders and fabrication shops seeking a proven solution for semiautomatic welding, the Lincoln Electric Magnum 300 MIG Gun (K470-1) stands out as a top-tier choice. This gun is designed to handle the rigors of daily industrial use while providing the precision required for high-quality welds. Rated at 300 Amps at 60% duty cycle with CO2 gas, it is perfectly suited for medium to heavy-duty applications in job shops, production lines, and manufacturing facilities. The K470-1 model comes equipped with a 10-foot cable, offering a practical balance between reach and cable management for bench work.

Built for Durability and Comfort

The construction of the Magnum 300 series focuses heavily on longevity and operator ergonomics. The gun features an armored gun tube that is electrically insulated, which not only protects the internal components but also optimizes performance when welding with fine wires. The cable itself is encased in an abrasion-resistant extruded rubber jacket, adding significant strength and resistance to cuts, burns, and wear that occur in busy workshop environments. To reduce welder fatigue during long shifts, the gun utilizes a classic curved handle design that is lightweight and perfectly balanced, ensuring a sure, confident grip.

Maintenance and Versatility

Maintenance is streamlined with the Magnum 300's design. It features a one-piece modular trigger assembly molded out of high-heat resistant material to withstand spatter and ensure long life. The silver contacts within the trigger provide clean electrical signals for reliable arc initiation every time. Additionally, the rotatable gooseneck (60-degree angle) allows welders to adjust the gun orientation to access tight spaces or awkward joint locations without straining their wrists. This gun is intended for use with wire diameters ranging from .035 to .045 inches (0.9-1.2 mm) and is compatible with Flux-Cored and MIG processes.
