A796F72 - Weldcraft A796F72 Long Alumina Cup #5 (10-Pack)

Precision Gas Coverage for Restricted Access Welds

The Weldcraft A796F72 Alumina Long Nozzle is a specialized consumable designed to solve one of the most common challenges in precision TIG welding: accessibility. Standard length nozzles often restrict the welder's view or physically prevent the torch from entering deep grooves, acute angles, or complex tube clusters. This #5 size nozzle (5/16-inch orifice) features an elongated body that extends the reach of the tungsten electrode while maintaining a focused shield of inert gas, ensuring that critical welds in tight spaces meet the highest quality standards.

Material Science and Durability

Manufactured from high-purity alumina ceramic, this nozzle is engineered to withstand the intense thermal cycling inherent in Gas Tungsten Arc Welding (GTAW). Alumina offers an excellent balance of impact resistance and thermal shock resistance, meaning these nozzles are less likely to crack when cooling down from high amperages compared to lower-grade ceramics. The material's dielectric strength also helps prevent high-frequency arching to the nozzle itself, ensuring the arc remains established between the tungsten and the workpiece.

Compatibility and Application

The A796F72 is specifically threaded to fit the front-end parts of the 9, 20, and 25 series TIG torches. These "small body" torches are favorites among pipe welders, aerospace fabricators, and motorsports builders for their maneuverability. By pairing these torches with this long nozzle, operators can execute root passes in pipe or weld inside collector assemblies with significantly improved visibility. The #5 orifice size provides a tight, columnar gas flow, which is ideal for lower amperage applications where turbulence must be minimized to prevent porosity.

Operational Efficiency

Supplied in a pack of 10, these nozzles ensure that fabrication shops remain stocked for continuous production. While alumina is durable, it is still a consumable item; having a consistent supply of high-quality Weldcraft replacements guarantees that production downtime is minimized. Whether used for stainless steel sanitary tubing or aluminum intake manifolds, the A796F72 provides the reach and reliability professional welders demand.
