KP2742-2-50R-B25 - Lincoln Magnum PRO 350A Slip-On Nozzle, 1/2" ID, 1/8" Recess (25 Pack)

Reliable Performance for Professional Welders

When you are under the hood for hours at a time, the last thing you want to worry about is your gun's front-end consumables failing prematurely. The Lincoln Electric KP2742-2-50R-B25 Magnum PRO nozzle is built to handle the heat of 350A welding jobs while keeping your downtime to a minimum. Designed for the Magnum PRO semi-automatic guns, these nozzles feature a slip-on design that welders love. No more fighting with seized threads when it's time to clean out spatter or change a tip—just pull it off, clean it up, and slide it back on. It stays secure while you weld but comes off easily when you need it to.

This specific nozzle features a 1/2-inch bore, which is a standard size for many general fabrication tasks, giving you excellent gas coverage without wasting shielding gas. The 1/8-inch recess is a key feature for many operators; it tucks the contact tip just inside the nozzle. This slight recess helps protect your tip from getting clogged with spatter or shorting out if you accidentally touch the work surface, while still keeping the arc visible and the stick-out manageable. It’s a great middle-ground setup for flat and horizontal fillet welds where you need consistent shielding.

Sold in a convenient 25-pack, this bulk option is perfect for busy shops. You won't have to constantly reorder or run to the supply cabinet every few days. The Magnum PRO series is designed to run cooler, meaning less spatter sticks to the nozzle in the first place, and what does stick is easier to remove. Whether you are welding mild steel, stainless, or aluminum, having a fresh stack of high-quality Lincoln nozzles ensures that your gas flow remains smooth and your welds stay porosity-free. Keep your arc stable and your production line moving with these durable, easy-to-use nozzles.
