The 24CT-50S is a high-performance replacement MIG welding nozzle designed to meet the rigorous demands of industrial fabrication. Engineered as a direct equivalent to the Tweco® 24A-50 (Stock No. 1240-1414), this nozzle features a 1/2-inch (12.7 mm) bore orifice, making it an ideal choice for medium-to-heavy duty welding applications where standard gas coverage is required without compromising joint access. The nozzle is manufactured from high-grade copper alloy, ensuring superior thermal conductivity and resistance to spatter adhesion, which prolongs the service life of the consumable even under high-amperage cycles.
A defining feature of this component is its Coarse Thread (CT) design. Unlike slip-on nozzles that rely on friction springs, the 24CT-50S threads directly onto the gas diffuser or nozzle insulator—specifically the 34CT insulator found on Tweco® Professional No. 3 and No. 4 series MIG guns. This threaded connection provides a mechanically secure fit, eliminating the risk of the nozzle becoming loose or misaligned during operation, which can lead to porosity and inconsistent shielding gas flow. The coarse thread pitch is robust and resistant to cross-threading, facilitating quick changeovers on the shop floor.
The nozzle geometry includes a standard 1/8-inch tip recess. This recess positioning places the contact tip slightly back from the nozzle exit, offering protection against radiant heat and reducing the likelihood of the tip shorting against the workpiece during tight corner welds. This configuration is widely preferred for short-circuit MIG welding and general fabrication. Rated for use with 300 Amp and 400 Amp air-cooled MIG guns, this nozzle maintains structural integrity in high-heat environments. This package includes two (2) nozzles, ensuring operators have immediate replacements available to minimize downtime.
