KP3160-1-50R-B25 - Magnum PRO 350A MIG Nozzle, Thread-on, Bottleneck, 1/8 Recess, 1/2 ID (25-Pack)

Technical Overview of the Lincoln Electric KP3160-1-50R-B25

The Lincoln Electric KP3160-1-50R-B25 is a high-performance gas nozzle engineered specifically for the Magnum PRO series of semi-automatic welding guns. Rated for 350 Amperes, this component is designed to withstand the thermal stresses of medium-to-heavy duty industrial welding cycles. The nozzle features a thread-on connection mechanism, which provides a mechanically secure interface with the diffuser. This threaded design is superior to slip-on alternatives in high-heat applications as it ensures consistent electrical isolation and maximizes thermal transfer away from the front end of the gun.

Geometrically, this nozzle utilizes a "Bottleneck" profile. This tapered shape reduces the external diameter at the tip, allowing for better access into tight joints and improved visibility of the weld puddle without compromising gas shielding coverage. The internal bore diameter is 1/2 inch (12.7 mm), a standard size suitable for a wide range of wire diameters and gas flow rates typically used in 350A applications. The nozzle is designed with a 1/8 inch (3.2 mm) recess. This recess depth places the contact tip slightly back from the nozzle edge, offering protection against short-circuiting against the workpiece and reducing the accumulation of spatter on the tip itself.

Manufactured to Lincoln Electric's precise tolerances, the KP3160-1-50R-B25 integrates seamlessly with Magnum PRO 350A contact tips and diffusers. The material composition is selected for high thermal conductivity, ensuring that heat generated during the arc is rapidly dissipated. This thermal management is critical for preventing the adhesion of spatter and prolonging the service life of both the nozzle and the internal consumables. This SKU represents a bulk package containing 25 individual units, intended for high-volume fabrication environments requiring consistent inventory of critical MIG consumables.
