K3136-3 - Lincoln Magnum PRO 550 Dual Procedure MIG Gun 20ft

Heavy-Duty 550A MIG Gun for Extreme Environments

The Lincoln Electric K3136-3 Magnum® PRO 550 Dual Schedule Welding Gun is the ultimate tool for professional welders requiring uncompromising power and reliability. Rated at 550 amps at 100% duty cycle (with CO2), this air-cooled gun is built to withstand the heat and stress of continuous high-output welding. Whether you are working in heavy equipment manufacturing or industrial fabrication, the Magnum PRO 550 delivers the consistency needed for high-quality welds.

Advanced Dual Procedure Technology

Efficiency is key in production welding, and the K3136-3 addresses this with its Dual Schedule feature. This technology puts control right at the welder's fingertips, allowing for seamless transitions between two pre-set welding schedules. This is ideal for applications involving tacking and final welding, or moving between vertical and flat positions, without the downtime associated with manual machine adjustments. The 20-foot cable length further enhances versatility, providing excellent access to large workpieces.

Superior Consumables and Maintenance

The Magnum PRO series utilizes Lincoln's premium Copper Plus® contact tips. Engineered with increased mass for better thermal conductivity, these tips stay cooler and last longer than conventional designs. The gun also incorporates an Anti-Seize™ thread design on both the tip and diffuser, which prevents the components from locking up due to heat cycling and spatter. This ensures that consumable changes are fast and easy, keeping your operation running smoothly.

Ergonomic Design for All-Day Welding

Welder fatigue can lead to inconsistent quality, which is why the K3136-3 features Lincoln's Comfort Grip™ design. The handle is ergonomically shaped to fit comfortably in the hand, providing a secure grip that minimizes strain. The gun is balanced to reduce wrist torque, making it easier to manipulate in various positions. Combined with a rugged, abrasion-resistant cable jacket and aircraft-grade aluminum components, this MIG gun offers a perfect blend of durability and usability for the professional welder.
