The Lincoln Electric Magnum® PRO 100SG Spool Gun (K3421-1) is the ultimate accessory for welders looking to expand their capabilities into aluminum fabrication. Designed specifically for use with Lincoln Electric's popular POWER MIG® series (including the 140, 180, and 210 MP models), this spool gun solves the common challenges associated with feeding soft aluminum wire. By locating the wire spool directly on the gun, it minimizes the distance the wire must travel, effectively eliminating the friction and birdnesting often encountered when pushing soft wire through standard long MIG cables.
Weighing in at just 3.5 lbs (1.6 kg), the 100SG is engineered for operator comfort. The ergonomic handle features a cushioned grip that reduces hand fatigue during extended welding sessions, while the well-balanced design makes it easy to maneuver in tight spaces. The unit comes equipped with a generous 10 ft. (3.0 m) gun cable, providing ample reach for working around large projects or vehicles without moving the power source constantly.
What sets the Magnum PRO 100SG apart is its utilization of Magnum® PRO consumables. These premium contact tips and nozzles are designed with Copper Plus™ technology, which improves heat dissipation and extends the life of the tip compared to standard consumables. The Anti-Seize™ thread design prevents the tip and diffuser from fusing, ensuring that maintenance is quick and frustration-free. Whether you are an automotive enthusiast, a hobbyist, or a light industrial fabricator, the K3421-1 provides a professional-grade aluminum welding experience at an accessible price point.
