K2651-4 - Lincoln K2651-4 Magnum PRO 250 MIG Gun

Industrial Grade Performance with the Magnum PRO 250

The Lincoln Electric Magnum® PRO 250 Welding Gun (K2651-4) is engineered for professionals who demand reliability and endurance in the toughest industrial environments. Rated at a full 250 Amps with a 100% duty cycle using both CO2 and mixed gases, this semi-automatic gun is designed to minimize downtime and maximize throughput. Unlike standard guns that may overheat during prolonged use, the Magnum PRO 250 is built to withstand high-amperage applications continuously, making it an ideal choice for heavy fabrication, structural steel, and manufacturing sectors.

Advanced Consumable Technology

A standout feature of the K2651-4 is the integration of Lincoln Electric's Copper Plus® Contact Tips. These tips are designed with a larger diameter and greater mass compared to standard contact tips. This engineering improvement significantly enhances heat dissipation, keeping the tip cooler during operation. The result is a dramatic increase in tip life and a reduction in the frequency of consumable changes, which directly translates to lower operating costs and higher productivity. The gun also utilizes a secure thread-on gas nozzle and diffuser system, ensuring tight connections and consistent gas coverage.

Ergonomics and Usability

Operator comfort is critical for maintaining weld quality over long shifts. The Magnum PRO 250 features the Comfort Grip™ design, a barrel-style handle that is lightweight and perfectly balanced. This ergonomic profile allows for multiple hand positions, reducing wrist strain and fatigue regardless of how the welder holds the gun. The 25-foot cable length provides exceptional reach, allowing operators to work on large assemblies without constantly moving the wire feeder or power source. Supported by the Lincoln PRO Select™ system, this gun is tailored for actual welding amperage needs rather than just machine ratings, ensuring you have the right tool for the job.
