KP3583-1-62R-B25 - Lincoln KP3583-1-62R-B25 Magnum PRO 550A Nozzle Front End (25-Pack)

Reliable Performance for Heavy Duty Welding

When you are pushing 550 amps on a heavy fabrication job, you need consumables that can take the heat. The Lincoln Electric Magnum PRO Heavy Duty Nozzle Front End (KP3583-1-62R-B25) is built exactly for that purpose. Designed as part of the Magnum PRO two-piece nozzle system, this front end allows you to swap out just the business end of your nozzle when it gets beat up, saving you money and keeping your gun running longer without a full assembly replacement.

This specific model features a 5/8-inch bore, which is the go-to size for many structural and manufacturing applications, offering a solid balance of gas coverage and access. The 1/8-inch recess is perfect for protecting your contact tip from the intense heat of the arc and minimizing the risk of bridging spatter, which can cause downtime. Whether you are running solid wire or flux-cored, the heavy-duty construction ensures the nozzle holds its shape and resists spatter adhesion better than standard duty parts.

The threaded design makes changing the front end quick and easy—just unscrew the old one and spin on the new one. No more fighting with slip-on nozzles that get stuck or loose over time. With this 25-pack, you can keep your station stocked and minimize interruptions. These nozzles are compatible with Magnum PRO 550A guns and are an essential part of keeping your welding operations smooth and efficient.
