KP26CT-75-R - Lincoln Electric Magnum 550 Gas Nozzle 3/4" ID Coarse Thread

Heavy-Duty Gas Shielding for Magnum 550 Systems

The Lincoln Electric KP26CT-75-R Gas Nozzle is a premium consumable component engineered specifically for high-performance industrial welding environments. Designed to integrate seamlessly with Magnum 550 semiautomatic MIG guns, this nozzle plays a critical role in maintaining arc stability and weld quality. With a substantial 3/4-inch (19.1 mm) inner diameter, it provides a broad and consistent envelope of shielding gas, ensuring that the weld pool remains protected from atmospheric contamination even during high-deposition welding. This large bore is particularly advantageous when working with larger diameter wires or when welding at higher travel speeds where gas coverage is paramount.

Constructed to withstand the rigors of heavy fabrication, this nozzle is rated for applications up to 600 Amps. At these high amperage levels, radiant heat and spatter generation are significant factors. The KP26CT-75-R addresses these challenges with a robust design and a 1/4-inch tip recess. The recessed tip configuration places the contact tip slightly back inside the nozzle, offering a physical shield against molten spatter and reducing the thermal load on the tip itself. This design choice not only extends the life of your contact tips but also helps prevent electrical shorts that can occur if the tip inadvertently touches the workpiece or if spatter bridges the gap.

One of the standout features of this model is its coarse thread connection. In the harsh environment of a welding shop, fine threads can easily become cross-threaded or seized due to heat expansion and spatter accumulation. The coarse thread design of the KP26CT-75-R ensures a secure mechanical connection that remains easy to install and remove, even after prolonged exposure to welding heat. This facilitates quick changeovers and routine maintenance, minimizing downtime on the production line. Whether you are welding structural steel, heavy machinery, or pressure vessels, this Lincoln Electric gas nozzle delivers the reliability and performance required for professional results.

Proper maintenance of your MIG gun consumables is essential for optimal performance. The KP26CT-75-R is designed to be easily cleaned and reamed, ensuring that gas flow remains unobstructed. Its compatibility with the Magnum 550 series ensures that it fits perfectly with the gun's diffuser and insulator systems, maintaining the correct electrical isolation and gas flow dynamics. By choosing genuine Lincoln Electric parts, operators can trust in the consistency and durability of their equipment, ensuring that every weld meets the necessary specifications.
