The Tweco 24A-75 (Stock No. 1240-1202) is a premium heavy-duty MIG nozzle designed to meet the rigorous demands of high-amperage industrial fabrication. When welding at higher currents—typically above 300 amps—or when utilizing spray transfer modes, standard bore nozzles often fail to provide adequate shielding gas coverage. This can lead to porosity, oxidation, and weak welds. The Tweco 24A-75 solves this problem with its expansive 3/4-inch (19mm) bore, creating a wide envelope of shielding gas that fully protects the molten weld pool even under intense heat and fast travel speeds.
Time is money in any production environment, and the Tweco 24 Series nozzles are engineered to minimize downtime. The slip-on design works in conjunction with the Tweco 54A or HD54A gas diffusers, allowing welders to remove the nozzle instantly for cleaning or replacement without reaching for pliers or a wrench. This friction-fit system also allows for nozzle adjustability; you can slide the nozzle forward or backward to achieve the perfect contact tip recess or stick-out for your specific welding procedure. Constructed from high-quality copper alloy, this nozzle resists heat buildup and spatter adhesion, ensuring a longer service life compared to generic alternatives.
This nozzle is a standard component for Tweco No. 4 and No. 5 MIG guns, as well as the popular Spray Master series. It is particularly well-suited for structural steel fabrication, heavy equipment manufacturing, and aluminum welding where gas coverage is paramount. The internal insulation is robust, protecting the nozzle body from electrical shorts during operation. Whether you are running solid wire with mixed gas or flux-cored wire requiring gas shielding, the Tweco 24A-75 delivers the consistent performance professional welders rely on.
