KP2742-1-38S-B25 - Lincoln Magnum PRO 350A MIG Nozzle 1/8 Stickout 3/8 ID (25-Pack)

Lincoln Magnum PRO 350A Thread-On MIG Nozzle - 1/8" Stickout

Optimize your MIG welding performance with the Lincoln Electric KP2742-1-38S-B25 Magnum PRO Nozzle. Designed for professional welders who demand precision and durability, this nozzle is rated for 350 amps, making it suitable for a wide range of medium to heavy-duty welding applications. The defining feature of this specific model is its 1/8 inch (3.2 mm) stickout. Unlike flush or recessed nozzles, a stickout nozzle allows the contact tip to extend slightly beyond the nozzle face. This design is critical for applications requiring tight arc control and enhanced visibility, allowing the welder to see exactly where the wire is contacting the base metal.

The nozzle features a 3/8 inch (9.5 mm) inner diameter, which creates a concentrated gas shield. This is ideal for reaching into corners or welding on thinner materials where a wide gas envelope is not necessary. The thread-on design is a hallmark of the Magnum PRO series, providing a tight, vibration-resistant connection that stands up to the rigors of industrial environments. Unlike slip-on nozzles that can become loose over time due to thermal cycling, the thread-on mechanism ensures the nozzle stays firmly in place, maintaining proper alignment with the gas diffuser and contact tip. This alignment is crucial for preventing porosity and ensuring consistent weld quality.

Sold in a convenient pack of 25, these nozzles are perfect for outfitting a fleet of welding machines or stocking a tool crib. Lincoln Electric's commitment to quality means these nozzles are built to last, resisting spatter adhesion and deformation under heat. Regular replacement of worn nozzles is key to maintaining good shielding gas coverage and preventing weld defects. With the KP2742-1-38S-B25, you get a consumable that supports high productivity and excellent weld aesthetics. Upgrade your Magnum PRO setup with these reliable, high-performance nozzles and experience the difference in your daily welding operations.
