24A-50 - Tweco Style 24A-50 MIG Gun Nozzle 1/2 Inch Bore (2-Pack)

Technical Overview of the Tweco Style 24A-50 Nozzle

The Tweco Style 24A-50 Nozzle is a high-performance consumable designed for professional MIG welding operations. Engineered to fit Tweco Professional No. 2, No. 3, and No. 4 series MIG guns, this nozzle is an essential component for maintaining consistent gas shielding and weld quality. The nozzle features a standard 1/2-inch (12.7 mm) bore, making it versatile for a wide range of wire sizes and welding positions. It is rated for use in medium to heavy-duty applications with amperages up to 450 amps, ensuring reliability under demanding duty cycles.

Constructed from 122 DHP copper alloy tubing, the 24A-50 offers excellent thermal conductivity and resistance to spatter adhesion. The material choice ensures the nozzle maintains its structural integrity even during prolonged exposure to high welding temperatures. The nozzle utilizes a slip-on connection mechanism, designed to slide effortlessly over the standard 34A (Stock No. 1340-1100) nozzle insulator. This design not only facilitates quick replacements but also allows the welder to adjust the nozzle position relative to the contact tip. By sliding the nozzle forward or backward, operators can achieve the desired tip recess or protrusion, optimizing the arc characteristics for specific joint configurations.

Identification and inventory management are simplified thanks to the part number being roll-stamped directly onto the outside surface of the nozzle housing. This ensures that welders can verify they are using the correct component for their setup. Sold in a convenient pack of two, these nozzles provide a cost-effective solution for maintaining your welding equipment's performance. Whether used in fabrication shops, manufacturing plants, or field repairs, the 24A-50 delivers the durability and precision required for high-quality MIG welding.
