KP3583-1-75R - Lincoln Magnum PRO HD Nozzle Front, 3/4 Inch Bore, 1/8 Inch Recess

Built for the Grind: Magnum PRO Heavy Duty Nozzle

When you are running high amps and laying down heavy beads, your MIG gun's front end takes a beating. The Lincoln Electric KP3583-1-75R Magnum PRO Heavy Duty Nozzle Front End is built to handle the heat. Designed for professional welders using Magnum PRO 550A guns, this nozzle front end is all about durability and ease of use. If you are tired of nozzles that seize up or get clogged with spatter instantly, this is the upgrade your torch needs.

Spatter Doesn't Stick
One of the biggest frustrations on the line is stopping every few minutes to chip spatter out of your nozzle. This component features a premium nickel plating that reflects heat and creates a slick surface, making spatter fall right off or wipe away with a simple glove swipe. This keeps your gas flow smooth and your downtime low.

Easy On, Easy Off
We have all wrestled with a nozzle that has fused to the gun after a long shift. Lincoln designed this front end with coarse threads that resist cross-threading and seizing. Even after hours of thermal cycling—heating up and cooling down—you can easily unscrew this front end to check your contact tip or swap it out. No pipe wrenches required.

Optimized for Heavy Welding
With a massive 3/4-inch bore, this nozzle delivers a wide blanket of shielding gas, perfect for those wide weave beads or high-deposition spray transfer modes. The 1/8-inch recess tucks your contact tip safely inside the nozzle, protecting it from the intense heat of the arc and reducing the chance of shorting against the workpiece, all while keeping the puddle visible.

This is part of Lincoln's two-piece nozzle system. Instead of throwing away a whole heavy copper nozzle when the tip gets battered, you just replace this front end. It saves money for the shop and keeps your equipment running at peak performance.
