K3132-4 - Lincoln Magnum PRO 350 Dual Schedule MIG Gun 25ft

Industrial Grade Performance for Heavy Fabrication

The Lincoln Electric Magnum® PRO 350 Dual Schedule Welding Gun (K3132-4) is engineered to deliver exceptional performance in the most demanding industrial environments. Designed for semi-automatic MIG and flux-cored welding applications, this 25-foot air-cooled gun offers a robust 100% duty cycle at 350 Amps when using CO2 shielding gas. For mixed gas applications, it maintains a continuous 100% duty cycle at 285 Amps, ensuring consistent operation without overheating during prolonged welding sessions. The "Dual Schedule" feature is a critical productivity enhancer, allowing operators to toggle between two distinct welding procedures directly from the gun trigger, eliminating the need to return to the power source to adjust voltage or wire feed speed.

Durability is at the core of the Magnum PRO series. The gun utilizes Lincoln Electric's proprietary Copper Plus® contact tips, which feature a larger diameter and increased mass compared to standard tips. This design significantly improves heat dissipation, extending the lifespan of the consumable and reducing downtime for tip changes. Furthermore, the gun is constructed with high-quality copper and aircraft-grade aluminum parts, ensuring superior electrical conductivity and heat resistance. The patent-pending Anti-Seize™ tip and diffuser thread design prevents parts from fusing together, making maintenance quick and frustration-free.

Operator comfort is addressed through the ergonomic Comfort Grip™ handle. The barrel-style design is lightweight and perfectly balanced, reducing hand fatigue during long shifts. The gun also features the Secure-Lock™ gun tube system, which resists rotational slipping, providing a stable and predictable welding experience. Whether utilized in shipbuilding, heavy equipment manufacturing, or general construction, the K3132-4 provides the reliability and precision professional welders require.
