The Tweco 1220-1301 (Model 22T-37-SS) is a premium threaded gas nozzle designed for professional MIG welding applications. Part of the widely used Tweco 22 Series, this nozzle features a threaded base that screws directly onto compatible gas diffusers (such as the Tweco 52 series). This threaded connection provides a fixed, non-adjustable fit that ensures consistent nozzle-to-tip relationship and optimal gas coverage, eliminating the risk of the nozzle slipping or moving during operation.
With a 3/8-inch (9.5 mm) bore, this nozzle is specifically engineered for applications requiring access to tighter joints or where lower gas flow rates are sufficient. The smaller bore diameter helps concentrate shielding gas around the weld pool, making it effective for short-circuit transfer modes and thinner gauge materials. The nozzle is constructed from a durable copper alloy that withstands high radiant heat and resists the buildup of welding spatter, ensuring a longer service life and reduced downtime for cleaning.
This unit is "Self-Insulated," featuring internal insulation material that prevents the nozzle shell from becoming electrically live, thereby reducing the risk of arcing if the nozzle accidentally contacts the workpiece. It is compatible with Tweco Spray Master 250 series guns and standard Tweco #2 MIG guns equipped with threaded front-end consumables. Supplied in a convenient pack of two, these nozzles are essential consumables for fabricators seeking reliability and precision in their MIG welding setup.
