The Tweco 24CT-62-S (Stock Number 1264-1120) is a high-performance MIG gun nozzle engineered for professional industrial applications. This component is a critical part of the gas shielding system, designed to direct shielding gas around the weld pool to prevent atmospheric contamination. It features a 5/8-inch (15.9 mm) bore, which is the industry standard for a wide range of amperage settings and wire diameters, offering a balanced gas flow profile that suits both short-circuit and spray transfer modes.
A defining feature of the 24CT series is the Coarse Thread (CT) interface. Unlike fine-threaded nozzles that can cross-thread or seize due to thermal expansion and spatter buildup, the coarse thread design engages fully with only a 1/2 turn. This engineering choice facilitates rapid removal for spatter cleaning or contact tip changes, directly impacting operational efficiency. The nozzle is self-insulated, meaning the electrical insulation is integrated into the nozzle body, simplifying the front-end consumable stack-up and reducing the number of loose parts required for maintenance.
Constructed from a robust copper alloy, the 24CT-62-S offers excellent thermal conductivity, effectively drawing heat away from the front end of the gun to prolong consumable life. It is designed to fit Tweco Spray Master series guns (250, 350, 450 amps) as well as the classic Tweco Professional Number 2, 3, and 4 guns. When used with standard gas diffusers, it typically provides a flush contact tip relationship, ideal for general fabrication where visibility and gas coverage must be balanced.
