KP3583-1-62R - Lincoln Magnum PRO 550A Nozzle Front, 5/8 Bore, 1/8 Recess

Precision and Durability for Magnum PRO Systems

Upgrade your welding torch setup with the Lincoln Electric KP3583-1-62R Magnum PRO Heavy Duty Nozzle Front End. This premium consumable is a critical component for professional welders utilizing the Magnum PRO 550A MIG gun platform. Engineered for high-performance applications, this nozzle front end is rated for up to 550 Amps, making it the ideal choice for heavy fabrication, structural steel work, and other industrial processes requiring high heat input and extended arc-on time. The split-nozzle architecture of the Magnum PRO line separates the nozzle into a body and a front end, allowing for more economical replacements and targeted maintenance.

The geometry of the KP3583-1-62R is optimized for versatility and arc stability. It features a 5/8-inch bore, a standard size that balances gas flow velocity with coverage area, suitable for a wide range of wire diameters and transfer modes. The 1/8-inch recess positions the contact tip slightly back from the nozzle edge. This recess is particularly beneficial for protecting the tip from radiant heat and spatter, thereby extending the life of your contact tips and reducing the frequency of changeovers. It also facilitates better visibility of the weld puddle in tight joints compared to flush or protruding tip configurations.

Superior Material Technology

Lincoln Electric has manufactured this nozzle front end with a focus on longevity and ease of use. The exterior is coated in a durable nickel plating which serves a dual purpose: it reflects radiant heat to keep the nozzle cooler, and it provides a non-stick surface that repels welding spatter. This significantly reduces the time spent scraping out nozzles and applying anti-spatter compounds. Additionally, the connection point utilizes large, coarse threads. These threads are far less likely to cross-thread or seize due to thermal expansion and contraction compared to fine threads, ensuring that the front end can be removed by hand or with minimal tool force even after being subjected to extreme welding temperatures.
