12441028 - Tweco 24CT-62-S MIG Nozzle, 5/8" Bore, Coarse Thread

Technical Overview of the Tweco 24CT-62-S MIG Nozzle

The Tweco 24CT-62-S (Part Number 1244-1028) is a high-performance MIG welding nozzle designed for professional industrial applications. Engineered by ESAB under the Tweco brand, this nozzle belongs to the 24CT series, characterized by its coarse thread design and self-insulated architecture. The unit features a 5/8-inch (15.9 mm) bore, which is a standard size for a wide range of medium to heavy-duty welding tasks, providing a balanced gas coverage profile that suits both short-circuit and spray transfer modes.

Constructed from a high-grade copper alloy, the 24CT-62-S is built to withstand significant thermal stress and resist the adhesion of welding spatter. The "CT" in the model designation stands for Coarse Thread, a feature that significantly reduces the time required for nozzle changes compared to fine-threaded alternatives. This design is particularly beneficial in high-throughput environments where downtime must be minimized. Furthermore, the nozzle is self-insulated, meaning the electrical insulation is integrated directly into the nozzle body, eliminating the need for a separate insulator part and simplifying inventory management.

This nozzle is fully compatible with Tweco Spray Master series guns (250, 350, 450 amps) as well as the classic Tweco Professional Number 2, 3, and 4 series MIG guns. It is designed to seat securely over the gas diffuser, ensuring concentricity and consistent shielding gas flow. The 1244-1028 stock code ensures you are receiving the genuine OEM part, manufactured to precise tolerances for optimal arc stability and weld quality.
