K2651-3 - Lincoln Magnum PRO 250 MIG Gun, 20ft, 250A, PowerMIG Backend

Industrial Performance for High-Amperage Applications

The Lincoln Electric Magnum® PRO 250 Semi-Automatic MIG Gun (K2651-3) is engineered for fabrication environments where downtime is not an option. Rated at a robust 250 amps at 100% duty cycle using mixed gases or CO2, this gun delivers consistent electrical conductivity and arc stability even during prolonged welding sessions. The 20-foot cable assembly provides significant reach, allowing operators to access joints on large assemblies without constantly repositioning the wire feeder or power source. This specific model is configured with a backend connection compatible with Lincoln Electric PowerMIG® series machines, ensuring a seamless integration into your existing fleet.

Advanced Consumable Technology

At the core of the Magnum PRO series is the utilization of Lincoln's proprietary Copper Plus® Contact Tips. These tips are designed with a larger diameter and greater mass than standard industry tips, which dramatically improves heat dissipation. By keeping the tip cooler, the risk of wire burn-back and tip fusion is minimized, extending the lifespan of the consumable and reducing the frequency of changeovers. The gun also utilizes a secure thread-on gas nozzle and diffuser system, which ensures tight gas coverage and prevents gas leakage that could lead to porosity in the weld.

Rugged Construction and Versatility

Built to withstand the rigors of heavy industry, the Magnum PRO 250 features an industrial-grade cable jacket that resists cuts, burns, and abrasion. The gun is capable of feeding a wide range of wire diameters, from 0.035 inches up to 5/64 inches, making it versatile enough for sheet metal work as well as heavier structural plate. Whether the application calls for standard MIG (GMAW), Pulsed MIG (GMAW-P), or Flux-Cored (FCAW) welding, this gun provides the smooth wire feeding and reliable power transfer required for code-quality welds.
