Lincoln Electric KP3161-1-62R-B25 Magnum PRO Nozzle Overview

Optimize your MIG welding setup with the Lincoln Electric KP3161-1-62R-B25 Magnum PRO Gas Nozzle. Designed specifically for use with Magnum PRO Semi-Automatic Welding Guns, this nozzle is built to withstand the rigors of 550A welding procedures. The key to its performance lies in the proprietary Magnum PRO consumable system, which emphasizes cool operation and longevity. The nozzle features a robust thread-on interface that not only secures it firmly to the diffuser but also facilitates efficient heat transfer, keeping the front end of your gun cooler during long welds.

Technical Specifications & Benefits:

• Bottleneck Design: The tapered profile improves joint access and puddle visibility, crucial for precision work in corners or tight spaces.
• 5/8" Bore: The 15.9 mm inner diameter balances gas flow velocity and coverage area, suitable for standard wire sizes and transfer modes.
• 1/8" Recess: A 3.2 mm recess helps prevent the contact tip from overheating and reduces the likelihood of arcing against the workpiece, while still maintaining proper electrical stick-out.

This 25-pack bulk configuration ensures that your welding stations remain stocked, minimizing interruptions in production. Whether you are welding structural steel, heavy equipment, or general fabrication projects, the KP3161-1-62R-B25 delivers the consistency and durability expected from Lincoln Electric. Pair these nozzles with Magnum PRO contact tips and diffusers for a fully optimized front-end solution that reduces spatter adhesion and maintenance frequency.
