12201110 - Tweco 22-50 MIG Gun Nozzle 1/2 Inch Bore (2-Pack)

Tweco 22-50 Standard Adjustable Nozzle (Pack of 2)

The Tweco 22-50 (Stock No. 1220-1110) is a standard replacement MIG gun nozzle designed for the widely used Tweco Professional Series and WeldSkill MIG guns. This package contains two (2) genuine Tweco nozzles, ensuring you have a backup on hand for continuous welding operations. The nozzle features a 0.500-inch (1/2") bore, which is the industry standard for general-purpose MIG welding, providing a balanced flow of shielding gas for stable arc characteristics and clean weld deposits.

Engineered as part of the 22 Series, this nozzle utilizes an adjustable slip-on connection. This design allows the operator to slide the nozzle over the gas diffuser (typically Series 32 or 52) to achieve the desired contact tip recess or stick-out. This adjustability is critical for managing heat input and visibility in different welding positions. The nozzle is constructed from a high-quality copper alloy, selected for its excellent thermal conductivity and resistance to spatter adhesion, which prolongs the service life of the consumable.

Compatibility is broad, fitting Tweco No. 2, No. 3, and No. 4 air-cooled MIG guns, as well as various other MIG guns that utilize the Tweco style front-end consumables. The 3-piece construction includes the outer copper shell, a high-temperature insulator, and an insert, ensuring electrical isolation from the contact tip and diffuser. Whether for fabrication, automotive repair, or industrial manufacturing, the 22-50 nozzle delivers reliable performance and durability.
