KP3583-1-75R-B25 - Lincoln Magnum PRO HD Nozzle Front End 3/4-inch Recessed (25-Pack)

Built for the Grind: Heavy Duty Performance

When you are under the hood running high amps, the last thing you need is a nozzle that melts, clogs, or fuses to your contact tip. The Lincoln Electric Magnum PRO Heavy Duty Nozzle Front End (KP3583-1-75R-B25) is built to withstand the intense heat of heavy fabrication. Designed specifically for the Magnum PRO 550A series guns, this nozzle front end is the business end of the two-piece nozzle system. Instead of tossing the whole nozzle when the tip gets battered, you just swap out this front cap and keep welding. It’s a smarter way to work that keeps your gun running cooler and your downtime lower.

This specific model features a wide 3/4-inch bore. That extra space is perfect for high-heat spray transfer modes or when you are laying down big beads and need maximum gas coverage to keep the puddle clean. The 1/8-inch recess is a welder favorite because it keeps your contact tip tucked away safely. This helps prevent those accidental arc-outs when you are working in tight corners and keeps the tip cleaner from spatter buildup. The recess also acts as a mechanical shield, extending the life of your contact tips.

Coming in a pack of 25, this bulk supply ensures you have plenty of backups in your tool crib or gang box. The heavy-duty construction resists spatter sticking, meaning you spend less time banging your gun or scraping out the nozzle and more time burning wire. Whether you are welding structural steel, heavy equipment, or pipe, these nozzle front ends deliver the consistency and durability professional welders demand from the Lincoln Electric Magnum PRO line.
