KP3583-1-75F - Magnum PRO 550A Flush Nozzle Front End 3/4-Inch

Built for High-Heat Performance

When you are pushing high amps and laying down serious beads, your MIG gun's front end takes the brunt of the punishment. The Lincoln Electric KP3583-1-75F Magnum PRO Heavy Duty Nozzle Front End is built to handle the heat without failing. Designed specifically for the Magnum PRO 550A series, this nozzle front end features a large 3/4-inch bore, providing excellent gas coverage for heavy structural welds or spray transfer modes where atmospheric contamination must be absolutely eliminated.

Every welder knows the frustration of a nozzle fused to the gun or clogged with stubborn spatter. Lincoln Electric addresses these pain points directly with this heavy-duty component. The nozzle features high-quality nickel plating which acts as a shield against spatter; instead of bonding to the metal, spatter is easily wiped or tapped away, keeping your gas flow smooth and your focus on the puddle. Additionally, the coarse thread design is a game-changer for maintenance. Even after long duty cycles at high amperage, the coarse threads resist seizing, allowing you to unscrew the front end easily by hand or with minimal force from pliers.

The "Flush" design of this nozzle means your contact tip sits flush with the end of the nozzle. This is often preferred for better visibility of the arc and puddle, as well as for getting into tighter joints where a recessed tip might limit your stick-out options. Because this is part of a two-piece system, you don't have to throw away the whole nozzle assembly when the tip gets beat up. You just swap out this front end, screw on a fresh one, and get back to burning wire. It is a rugged, reliable solution for professional fabricators who demand consistency.

Why Welders Choose This Nozzle:

• Easy Cleaning: Nickel plating keeps spatter from sticking.
• No Seizing: Coarse threads mean it comes off when you want it to.
• High Amp Rating: Handles 550A heat without melting down.
• Cost Effective: Replace just the tip, not the whole assembly.
