KP2742-1-38R-B25 - Lincoln Magnum PRO 350A MIG Nozzle, 3/8 Bore, 1/8 Recess (25 Pack)

Reliable Performance with Lincoln Magnum PRO Nozzles

Keep your welding line moving and your arcs stable with the Lincoln Electric Magnum PRO 350A Gas Nozzle. Designed for professional welders who demand consistency, this nozzle (Part Number KP2742-1-38R-B25) is built to withstand the rigors of daily industrial use. The 350-amp rating ensures that it can handle significant heat without deforming or degrading rapidly, making it a trusty companion for your Magnum PRO MIG gun. The thread-on design is a favorite among operators because it stays put—no more wobbling nozzles or gas leaks caused by a loose fit. Just thread it on, and you are ready to lay down beads.

The specific geometry of this nozzle is tailored for precision and protection. With a 3/8-inch bore, you get a tight, controlled gas flow that is perfect for getting into corners or welding thinner materials where a massive gas plume isn't necessary. The 1/8-inch recess is a critical feature for longevity; by keeping the contact tip tucked away, you reduce the risk of burning it up on the plate and help prevent spatter bridges that can block gas flow. This means you spend less time scraping out your nozzle and more time welding.

This 25-pack is the smart choice for shops that want to ensure they never run dry on critical consumables. The Magnum PRO platform is renowned for its "Copper Plus" technology and heat dissipation capabilities, and these nozzles play a huge role in that system. By effectively pulling heat away from the arc zone, they help your contact tips last longer and keep the gun handle cooler in your hand. Upgrade your consumable inventory with genuine Lincoln Electric parts and experience the difference in durability and arc performance.
