796F71 - Weldcraft Long Lava Nozzle #4 (1/4 Inch) for 9/20 Series TIG Torches

High-Performance Heat Resistance for Precision TIG Welding

The Weldcraft 796F71 Long Lava Nozzle is a specialized consumable designed to solve specific challenges in the TIG welding process. When working in confined spaces—such as inside pipe clusters, corners of manifolds, or deep recesses in castings—standard alumina nozzles often struggle. The proximity to the base metal causes intense heat to be reflected back onto the nozzle, which can lead to rapid thermal expansion and cracking. This product addresses that failure point by utilizing Lava material, a natural stone-based ceramic known for its superior thermal shock resistance and durability under reflected heat loads.

This nozzle features a #4 orifice (1/4 inch), creating a tight, focused column of shielding gas that is ideal for precision work on thinner materials or root passes where turbulence must be minimized. The "Long" design is the critical feature for accessibility; it extends the tungsten electrode's reach without compromising gas coverage, allowing the welder to maintain a proper arc length even when the torch body cannot fit close to the joint. This improved access translates directly to better weld quality, as the operator can maintain a comfortable torch angle and clear line of sight.

Compatibility is broad across the lightweight TIG torch spectrum. The 796F71 fits 9, 20, 22, and 25 series torches, making it a versatile addition to any professional welder's kit. Whether you are using an air-cooled WP-9 for field work or a water-cooled WP-20 for production fabrication, this nozzle integrates seamlessly with your existing collet bodies. Supplied in a pack of 10, this product ensures that fabrication shops and industrial maintenance teams have a reliable supply of high-performance consumables on hand, reducing downtime associated with frequent nozzle replacement.

By choosing Weldcraft's genuine parts, operators ensure consistent threading and fitment, preventing gas leaks that can lead to porosity. The Lava material's unique properties make it the preferred choice for applications where standard pink alumina cups fail prematurely due to heat stress.
