KP3161-1-62R-B25 - Lincoln Electric Magnum PRO 550A MIG Nozzle, Bottleneck, 5/8" ID, 1/8" Recess (25-Pack)

High-Performance Lincoln Electric Magnum PRO Consumables

The Lincoln Electric KP3161-1-62R-B25 is a bulk package of 25 premium gas nozzles designed for the Magnum PRO series of semi-automatic welding guns. Engineered for heavy industrial applications, these nozzles are rated for 550 amps, making them suitable for high-deposition welding where heat management is critical. The Magnum PRO platform is renowned for its durability and performance, and these nozzles are a key component in maintaining that standard. By utilizing a thread-on connection, the nozzle ensures a tight mechanical fit that maximizes thermal conductivity, drawing heat away from the front end of the gun to extend consumable life.

This specific nozzle features a bottleneck shape, which tapers towards the outlet. This design is essential for welders who need better visibility of the weld puddle or access to restricted joints that standard cylindrical nozzles cannot reach. With a 5/8-inch (15.9 mm) inner diameter, it provides a focused column of shielding gas, ensuring excellent coverage and porosity-free welds even at higher amperages. The 1/8-inch (3.2 mm) recess places the contact tip slightly back inside the nozzle, offering protection against short circuits and reducing the accumulation of spatter on the tip itself.

Supplied in a convenient 25-pack, the KP3161-1-62R-B25 is ideal for fabrication shops, manufacturing plants, and large-scale operations that require a steady supply of reliable consumables. Consistent performance, reduced downtime for changeovers, and the robust build quality of Lincoln Electric make these nozzles a smart investment for any professional welding environment.
