12301012 - Tweco 23-62 WeldSkill MIG Nozzle, 5/8" Bore, Flush Tip (Pack of 2)

Technical Overview of Tweco 1230-1012 Nozzles

The Tweco 1230-1012 is a package of two (2) WeldSkill series MIG gun nozzles, identified by the industry-standard part number 23-62. These nozzles are engineered to provide consistent shielding gas flow and arc protection in medium-to-heavy duty welding applications. The nozzle features a 5/8-inch (16mm) bore diameter, which is the standard size for most general fabrication tasks, offering a balance between gas coverage and accessibility.

Designed with a flush tip relationship, the contact tip sits even with the end of the nozzle. This geometry is versatile, suitable for short-circuit transfer and spray transfer modes, preventing the tip from shorting out against the workpiece while maintaining adequate stick-out visibility. The nozzle utilizes a slip-on connection mechanism, relying on a friction fit over the gas diffuser or nozzle insulator, which eliminates the need for threads and speeds up consumable changeovers during operation.

Manufactured from high-grade copper alloy, the 23-62 nozzle effectively dissipates heat, reducing spatter adhesion and prolonging the service life of the front-end consumables. It is fully compatible with Tweco Classic No. 2, No. 3, and No. 4 air-cooled MIG guns, as well as the Tweco WeldSkill and Spray Master series that utilize the 23 Series consumable platform. This specific SKU (1230-1012) is packaged as a pair, ensuring operators have immediate replacements available.
