12401111 - Tweco 24A-50 Slip-On MIG Nozzle 1/2 Inch Bore (Pack of 2)

Professional Grade Tweco 1240-1111 (24A-50) MIG Nozzles

Maximize the performance of your MIG welding equipment with the Tweco 1240-1111 (24A-50) Nozzle. Engineered for professional welders who demand reliability and precision, this nozzle is a cornerstone of the Tweco 24 Series consumable line. This package contains two (2) high-quality slip-on nozzles, designed to withstand the rigors of medium-to-heavy duty welding cycles. The 24A-50 is characterized by its 0.500-inch (1/2") bore orifice, which provides a focused column of shielding gas, essential for protecting the weld pool from atmospheric contamination and ensuring defect-free welds in mild steel, stainless steel, and aluminum applications.

The construction of the Tweco 24A-50 nozzle highlights its industrial pedigree. Manufactured from heavy-duty copper alloy, it offers superior thermal conductivity. This helps to pull heat away from the contact tip and diffuser, reducing the risk of burn-backs and extending the service life of your entire front-end assembly. The nozzle body is robust enough to withstand mechanical impact and resists the adhesion of weld spatter, making it easier to clean with standard nozzle dip or reamers. The slip-on design is a favorite among professionals for its speed; it allows for immediate access to the contact tip for quick changes, significantly reducing downtime on the production line.

Compatibility is a major advantage of the 1240-1111. It fits a broad spectrum of MIG guns, including the legendary Tweco Classic No. 2, 3, and 4, as well as the modern Spray Master series. It pairs perfectly with 34A and 34CT insulators and standard gas diffusers. The integrated electrical insulation is a critical safety feature, isolating the electrically live contact tip from the grounded nozzle shell, thereby preventing accidental arcing and protecting the operator and equipment. When precision, durability, and ease of use are paramount, the Tweco 24A-50 is the nozzle of choice for professional fabricators.
