24AH-62SS - Tweco 24AH-62-SS Adjustable MIG Nozzle, 5/8" Bore, Short Stub (2-Pack)

Technical Overview of the Tweco 24AH-62-SS Nozzle

The Tweco 24AH-62-SS (Part Number 1240-1221) is a premium heavy-duty MIG welding nozzle designed for professional industrial applications. Belonging to the renowned Tweco 24 Series, this nozzle is engineered to withstand the thermal stresses of high-amperage welding while maintaining precise dimensional stability. The "AH" designation indicates an Adjustable Heavy-Duty design, allowing the welder to slide the nozzle over the insulator to achieve the desired contact tip recess or stick-out, which is critical for controlling arc characteristics and shielding gas coverage.

This specific model features a 5/8-inch (0.625") bore, identified by the "62" in the model number, which provides a balanced gas flow suitable for a wide range of wire diameters and transfer modes, including short-circuit and spray transfer. The "SS" suffix denotes a "Short Stub" configuration. This design reduces the overall length of the front-end assembly compared to standard nozzles, thereby improving the welder's ability to access tight corners and confined spaces without compromising the shielding gas envelope. Manufactured from high-grade copper alloy, the 24AH-62-SS offers superior thermal conductivity, effectively drawing heat away from the front end to prolong consumable life.

Supplied in a package of two, these nozzles are compatible with standard Tweco No. 4 MIG guns and other MIG guns utilizing 24-series consumables. The robust wall thickness ensures resistance to deformation from drops and heat, while the smooth surface finish helps minimize spatter adhesion, facilitating easier cleaning and maintenance during operation.
