KP3160-1-50S-B25 - Lincoln Magnum PRO 350A Bottleneck Nozzle 1/8 Stickout 25-Pack

High-Performance Gas Shielding for Magnum PRO Systems

The Lincoln Electric KP3160-1-50S-B25 is a premium gas nozzle designed exclusively for the Magnum PRO 350A semi-automatic welding gun series. Engineered for industrial environments where durability and precision are paramount, this nozzle features a bottleneck geometry that tapers to a 1/2-inch (12.7 mm) inner diameter. This specific bore size strikes an optimal balance between gas coverage and accessibility, allowing operators to maintain effective shielding even when welding in restricted spaces or complex joint configurations. The nozzle is rated for 350 Amps, making it suitable for a wide range of medium to heavy-duty fabrication tasks.

A defining characteristic of this model is its 1/8-inch (3.2 mm) stickout specification. In this configuration, the contact tip protrudes slightly beyond the nozzle edge, providing the welder with superior visibility of the arc and the weld puddle. This is particularly advantageous for fillet welds and precision root passes where sightlines are critical. The thread-on connection mechanism is a key feature of the Magnum PRO platform; unlike friction-fit slip-on nozzles, the threaded interface ensures concentric alignment and significantly improves thermal transfer from the nozzle to the gun tube. This efficient heat dissipation helps keep the nozzle cooler during extended arc-on times, reducing spatter adhesion and prolonging the service life of the consumable.

Supplied in a bulk package of 25 units, this SKU is tailored for high-volume manufacturing operations that require consistent inventory of critical expendables. The robust copper alloy construction resists mechanical wear and thermal shock, ensuring that production lines remain active with minimal downtime for torch maintenance. By integrating seamlessly with Magnum PRO diffusers and insulators, these nozzles complete a high-performance front-end system designed to deliver consistent weld quality and operational efficiency.
