P23-50 - Tweco Style 23-50 Slip-On MIG Nozzle 1/2 Inch Bore

Industrial Grade P23-50 MIG Gun Nozzle

The P23-50 MIG Nozzle is a precision-manufactured consumable designed to meet the rigorous demands of industrial welding. Engineered as a direct aftermarket replacement for the industry-standard Tweco 23-50, this nozzle is fully compatible with Tweco No. 2 MIG guns and Lincoln Magnum 200, 250, 300, and 400 series guns equipped with Tweco-style front-end parts. It is specifically designed to mate with the 52FN gas diffuser, utilizing a friction-fit slip-on connection that ensures concentricity and stability during welding.

Optimized Gas Coverage:
With a 1/2-inch (0.500") bore diameter, this nozzle provides a focused column of shielding gas. This bore size is ideal for general-purpose welding applications using 0.030" to 0.045" wire diameters. It effectively shields the weld pool from nitrogen and oxygen absorption, which are the primary causes of porosity and brittle welds. The wall thickness is calibrated to absorb and dissipate heat efficiently, prolonging the service life of the nozzle even during extended duty cycles.

Durability and Maintenance:
Constructed from high-grade copper, the P23-50 resists mechanical deformation and spatter adhesion. The slip-on design is a key feature for maintenance efficiency; it eliminates the risk of seized threads common in threaded nozzle systems. Operators can quickly remove the nozzle to clear spatter from the gas diffuser ports or replace the contact tip, minimizing downtime. The integrated high-temperature insulator protects the gooseneck and ensures electrical isolation, critical for safety and preventing short circuits against the base metal.

Compatibility:
This nozzle is a versatile solution for mixed-fleet environments. It fits a wide range of guns that utilize the Tweco #2 consumable platform, making it a universal stock item for many shops. Whether you are welding mild steel, stainless, or aluminum (with appropriate liners), the P23-50 delivers consistent gas flow and arc protection.
