796F73 - Weldcraft 796F73 Long Lava Cup #6 (3/8") for 9/20 Torches

Technical Overview of the Weldcraft 796F73 Lava Nozzle

The Weldcraft 796F73 is a specialized #6 (3/8-inch) long lava nozzle designed to address specific thermal challenges in TIG welding applications. Unlike standard alumina nozzles, which are prone to cracking due to thermal expansion and contraction, this nozzle is manufactured from lava (ceramic). This material choice is critical for applications involving confined areas where excessive heat is reflected back into the nozzle assembly. Standard alumina nozzles shrink during manufacturing and can expand unevenly when subjected to high reflective heat, leading to structural failure. The lava composition of the 796F73 mitigates this issue, maintaining dimensional stability and structural integrity under severe thermal stress.

This nozzle features a long configuration, measuring approximately 1-7/8 inches in length, which facilitates access to recessed joints and deep corners without compromising gas shielding. It is engineered for compatibility with the 2 Series TIG torches, including models 9, 20, 22, and 25, as well as equivalent torches from other manufacturers such as CK Worldwide (2 Series), Lincoln, and Profax. The #6 orifice provides a 3/8-inch gas outlet, suitable for a wide range of amperage applications and tungsten sizes. Supplied in a pack of 10, these nozzles ensure consistent availability for high-volume fabrication environments requiring reliable shielding gas delivery in thermally aggressive setups.
