A53N25 - Weldcraft A53N25 #5 Alumina Cup for 24 Series Torches (10-Pack)

Reliable Gas Coverage for Precision TIG Applications

The Weldcraft A53N25 Alumina Nozzle is a critical consumable designed for the specific requirements of 24 Series TIG torches. In the realm of precision welding, where 24 series torches are often employed for their compact size and ability to access tight spaces, the quality of the shielding gas coverage is paramount. This nozzle features a #5 orifice, translating to a 5/16-inch (approximately 8mm) bore diameter. This size is widely regarded as a versatile standard for light-to-medium amperage applications, providing a focused column of shielding gas that protects the molten weld pool from atmospheric contamination without wasting expensive argon or helium.

Manufactured from high-grade alumina ceramic, these nozzles are engineered to withstand the thermal cycling inherent in TIG welding. Alumina (aluminum oxide) is the industry standard for general-purpose TIG cups due to its high melting point, electrical insulation properties, and reasonable mechanical strength. The A53N25 exhibits excellent thermal shock resistance, meaning it is less likely to crack when transitioning rapidly from high welding temperatures to ambient cooling. Furthermore, the material surface is designed to resist spatter adhesion, which is particularly beneficial when working on materials that may emit minor contaminants, ensuring that the gas flow path remains unobstructed and laminar.

This product is supplied as a pack of 10, a configuration that supports inventory management for industrial environments. Consistent replacement of nozzles is necessary to maintain weld integrity; a chipped or clogged nozzle can induce turbulence in the gas stream, leading to porosity or oxidation in the weld. By utilizing genuine Weldcraft components, operators ensure compatibility with the thread pitch and seating surfaces of standard 24 series collet bodies and gas lenses, thereby preventing gas leakage at the connection point. The A53N25 represents a professional-grade solution for maintaining the performance of micro-TIG torch setups.
