For professional welders who demand reliability and versatility, the Lincoln Electric Magnum PRO 450 Dual Schedule Welding Gun (K3134-4) delivers exceptional results. This 25-foot semiautomatic MIG gun is engineered for high-amperage applications, offering a robust 100% duty cycle at 450 amps with CO2. Whether you are working on heavy structural steel, manufacturing heavy machinery, or performing general fabrication, this gun provides the power and endurance needed to keep your arc on longer.

Key Benefits for the Pro Welder:

• Dual Schedule Convenience: Toggle between two pre-set welding schedules right from the gun trigger. This is perfect for applications requiring different settings for tacking vs. welding, or vertical vs. flat welds, saving you trips back to the machine.
• Superior Consumable Life: The Magnum PRO series uses Lincoln's exclusive Copper Plus® contact tips. These tips are designed with more mass to dissipate heat more effectively, lasting longer than standard tips and saving you money on consumables over time.
• Ergonomic Design: Welding all day can be exhausting. The Comfort Grip™ handle is designed to fit naturally in your hand, reducing strain and fatigue. The lightweight, balanced feel allows for better control and precision.

The K3134-4 is built tough. It features an industrial-grade construction with a Secure-Lock™ tube that prevents the gooseneck from twisting, ensuring your aim remains true. The Anti-Seize™ threads on the tip and diffuser mean you won't be fighting with stuck parts when it's time for a change-out. Compatible with wire diameters ranging from 0.035" to 5/64", this gun is versatile enough to handle a wide array of wire types, including solid MIG, pulsed MIG, and flux-cored wires. Upgrade to the Magnum PRO 450 and experience the difference that professional-grade equipment makes in your daily welding operations.
