OVERVIEW

Industrial-Grade Durability and Control

The Lincoln Electric Magnum PRO 350 Dual Schedule Welding Gun (K3132-3) represents the pinnacle of semi-automatic MIG welding technology designed for heavy industrial fabrication. Engineered to withstand the rigors of extreme environments, this air-cooled gun delivers a 100% duty cycle at 350 Amps when using CO2 shielding gas, ensuring continuous operation without overheating or downtime. The robust construction utilizes high-quality copper and aircraft-grade aluminum components, providing superior electrical contact and heat dissipation essential for high-amperage applications.

A defining feature of this model is the Dual Schedule capability. This integrated system allows operators to toggle between two distinct welding procedures directly from the gun trigger. This functionality is critical for complex assemblies requiring different settings for varying material thicknesses or positions, eliminating the non-productive time spent walking back to the wire feeder to adjust voltage or wire feed speed. The gun is equipped with a 20-foot cable, offering an extended reach that further enhances operational flexibility in large-scale shipbuilding, construction, and heavy equipment manufacturing environments.

Maintenance and longevity are core to the Magnum PRO series design. The gun features Lincoln's patent-pending Anti-Seize tip and diffuser thread design, which significantly reduces the likelihood of parts fusing together under thermal stress. Furthermore, the Secure-Lock gun tube prevents rotational slipping, ensuring consistent alignment and arc control. Compatible with wire diameters ranging from 0.035 inches to 5/64 inches, the K3132-3 is a versatile tool for MIG, Pulsed MIG, and Flux-Cored processes.

FAQ

The Dual Schedule feature allows the welder to switch between two different sets of welding parameters (such as voltage and wire feed speed) using a switch on the gun, without having to return to the wire feeder.

This gun is rated at 100% duty cycle at 350 Amps when using CO2 gas, and 100% duty cycle at 285 Amps when using mixed gas.

It uses Lincoln Electric Magnum PRO consumables, including Copper Plus contact tips (KP2744 series), thread-on gas nozzles (KP2742 series), and thread-on diffusers (KP2746 series).

The K3132-3 model comes with a 20-foot (6.1 meter) cable.

The Magnum PRO 350 is designed to feed wire diameters ranging from 0.035 inches (0.9 mm) up to 5/64 inches (2.0 mm).

Yes, the Magnum PRO 350 is suitable for MIG, Pulsed MIG, and Flux-Cored welding processes.

The K3132-3 is an air-cooled semi-automatic MIG gun.
