K3132-1 - Lincoln Magnum PRO 350 Dual Schedule MIG Gun, 10ft, 350A

Lincoln Electric Magnum PRO 350 Dual Schedule Welding Gun (K3132-1)

The Lincoln Electric Magnum PRO 350 Dual Schedule Welding Gun (K3132-1) is a high-performance semiautomatic MIG gun designed for the most demanding industrial applications. Engineered to operate at a 100% duty cycle at 350 Amps with CO2 shielding gas (285 Amps with mixed gas), this air-cooled gun ensures continuous operation without overheating, making it ideal for heavy fabrication, shipbuilding, and structural construction. The 10-foot cable length provides adequate reach for standard bench and cell welding setups while maintaining consistent wire feeding characteristics.

A defining feature of this model is its Dual Schedule capability. This functionality allows the operator to toggle between two distinct welding procedures (typically voltage and wire feed speed) directly from the gun, provided the wire feeder supports dual schedule input. This significantly enhances efficiency in applications requiring frequent parameter changes, such as switching between root and fill passes or vertical and flat positions. The gun is compatible with a wide range of wire diameters, from 0.035 inch to 5/64 inch, accommodating MIG, Pulsed MIG, and Flux-Cored processes.

Technologically, the Magnum PRO 350 integrates Lincoln's Copper Plus® Contact Tips. These tips are designed with a larger diameter and greater mass than standard tips, improving heat dissipation and extending consumable life. The gun also features a patent-pending Anti-Seize tip and diffuser thread design, which prevents the components from fusing together under high heat, thereby simplifying maintenance. The Secure-Lock gun tube design prevents rotational slipping, ensuring the gun neck stays fixed in the desired orientation during use. Constructed with industrial-grade components, including aircraft-grade aluminum parts and high-quality copper, the K3132-1 is built to withstand the rigors of extreme environments while offering ease of serviceability with its 4-trigger lead design for fast field repairs.
