Classic Comfort Meets High-Amperage Power

When your welding projects demand serious power and reliability, the Lincoln Electric Magnum 550 Welding Gun (K598-11) delivers. This 15-foot semiautomatic MIG gun is built for welders who need to push high amperage without sacrificing comfort. Rated for 550 amps at a 60% duty cycle with CO2, the Magnum 550 is ready to tackle the thickest materials and the toughest jobs. Whether you are running heavy flux-cored wire or solid MIG wire, this gun is configured to handle large diameters from 5/64 inch up to 3/32 inch, giving you the deposition rates needed for heavy equipment repair and structural fabrication.

The Magnum 550 features the legendary classic curved handle that welders have trusted for years. Its ergonomic design fits naturally in the hand, providing excellent balance and reducing the strain on your wrist and forearm during extended use. The handle isn't just comfortable; it's built to last. The one-piece modular trigger is constructed from heat-resistant materials to shrug off spatter and heat, while the silver contacts inside ensure you get a positive arc start every single time you pull the trigger. No more misfires or intermittent connections—just reliable performance shift after shift.

Lincoln Electric has designed this gun to survive the real-world abuse of a welding shop. The gun tube is protected by an armored, insulated metal jacket, and the cable is wrapped in a tough extruded rubber jacket that resists abrasion and cuts. The rotatable gooseneck adds versatility, allowing you to position the nozzle exactly where you need it, even in tight corners. This package comes complete with a contact tip, gas diffuser, gas nozzle, insulator, and cable liner, so you are ready to hook up and weld. Upgrade your welding setup with the Magnum 550 and experience the perfect blend of heavy-duty capability and operator-focused design.
