K2650-1 - Lincoln Magnum PRO 550 Fume Extraction Gun, 15ft, 550A

Heavy-Duty Fume Extraction for Industrial Fabrication

The Lincoln Electric Magnum® PRO 550 Fume Welding Gun (K2650-1) is engineered to meet the rigorous demands of high-productivity fabrication environments. Designed for semiautomatic welding applications where arc time is extensive, this gun combines robust power delivery with essential safety features. It is rated at 550 Amps at 100% duty cycle when using CO2 shielding gas, and 375 Amps at 100% duty cycle with mixed gases, making it a powerhouse for structural steel, heavy equipment manufacturing, and general fabrication.

Advanced Fume Capture Technology

Source capture is widely recognized as the most effective method for controlling welding fumes. The Magnum PRO 550 integrates a high-efficiency vacuum pathway directly into the gun assembly, removing hazardous particulate matter right at the arc before it enters the operator's breathing zone. This design aids in compliance with safety regulations while maintaining a clear view of the weld pool. The gun includes a specialized FCAW smoke extractor nozzle, ensuring versatility across different welding processes including MIG, Pulsed MIG, and Flux-Cored welding.

Industrial Grade Durability

Lincoln Electric has constructed the Magnum PRO series with high-quality copper and aluminum components. This material selection ensures superior electrical contact and optimal heat dissipation, which is critical for maintaining the 100% duty cycle rating. The gun features Lincoln's patent-pending Anti-Seize™ tip and diffuser thread design. This innovation significantly reduces the likelihood of parts fusing and seizing, a common issue in high-heat applications, thereby simplifying maintenance and reducing downtime. Additionally, the gun utilizes Lincoln Copper Plus™ Contact Tips, which feature a larger diameter and greater mass to improve heat transfer and extend tip life compared to standard consumables.

Ergonomics and Cable Protection

Despite its heavy-duty capabilities, the K2650-1 is designed with operator comfort in mind. The Comfort Grip™ handle utilizes a barrel style that accommodates various hand positions, reducing fatigue during long shifts. An innovative strain relief system swivels to alleviate pressure on the welder's wrist and includes flexible bellows for easier out-of-position work. To ensure longevity in harsh shop environments, the fume hose and gun cable are protected by durable Kevlar® sheathing, resisting cuts, abrasion, and heat damage.
