K497-21 - Lincoln Magnum 200 MIG Gun Package, 15ft, .035-.045 Liner

Technical Overview of the Lincoln Magnum 200 (K497-21)

The Lincoln Electric Magnum 200 Semiautomatic Welding Gun (K497-21) is an air-cooled MIG gun engineered for reliability and performance in light job shop and fabrication environments. Rated at 200 Amps with a 60% duty cycle using CO2 gas, this gun assembly is designed to handle continuous feed arc welding wires, including both solid MIG and flux-cored varieties. This specific package comes equipped with a 15-foot cable and a liner configuration optimized for .035 to .045 inch (0.9 to 1.2 mm) wire diameters, although the gun platform itself is capable of handling fine wires down to .025 inches with the appropriate liner changes.

Structurally, the Magnum 200 is built to withstand the rigors of daily industrial use. The gun tube is armored with an electrically insulated metal jacket that not only optimizes fine wire welding performance but also reflects radiant heat, protecting the internal components. The cable is encased in an abrasion-resistant, extruded rubber jacket that adds significant tensile strength and prevents wear from dragging across shop floors. A rugged strain relief system is integrated to reduce acute cable angles, thereby enhancing wire feedability and protecting the internal liner from kinking.

The K497-21 features a one-piece modular trigger assembly molded from high heat-resistant material. This design incorporates high-quality silver contacts to ensure long operational life and clean electrical signal transmission, minimizing the risk of trigger failure during critical welds. The gun also boasts a rotatable gooseneck (60-degree bend), allowing operators to adjust the torch angle for optimal access to tight spaces or awkward joint configurations. The package includes the K466-10 gun connector, ensuring compatibility with a wide range of Lincoln Electric wire feeders and power sources. Expendable parts, such as contact tips and nozzles, are compatible with standard industry designs, ensuring ease of maintenance and parts availability.
