The Tweco 1240-1130 (Model 24A-75) is a premium adjustable MIG nozzle designed for heavy-duty industrial welding applications. Part of the renowned Tweco 24 Series, this nozzle is engineered to fit Tweco No. 4 and Spray Master 450 MIG guns, which are staples in high-amperage fabrication environments. The "75" in the model number designates a large 0.750-inch (3/4") bore diameter, providing a wide umbrella of shielding gas coverage essential for protecting the weld pool at higher currents or when welding reactive metals.
Constructed from high-grade copper alloy, the 24A-75 offers excellent thermal conductivity and durability, resisting spatter adhesion and deformation under extreme heat. The "A" designation signifies its adjustable nature; it slips onto the gas diffuser/insulator assembly, allowing the operator to slide the nozzle forward or backward. This adjustability is critical for managing contact tip recess (stick-out), enabling the welder to adapt to different joint configurations and welding positions on the fly.
This product is supplied as a package of two nozzles, ensuring you have a spare on hand for continuous production. Whether you are performing structural steel fabrication, heavy equipment repair, or general manufacturing, the Tweco 24A-75 ensures consistent gas flow and arc stability.
