13N16 - Weldcraft 13N16 Lava Cup #6 for 9/20 Series Torches (10-Pack)

High-Performance Heat Resistance with Weldcraft 13N16 Lava Nozzles

The Weldcraft 13N16 Lava TIG Nozzle is a specialized consumable designed to address the challenges of high-heat TIG welding applications. Unlike standard alumina oxide nozzles, which serve well for general-purpose welding, these nozzles are manufactured from Lava, a unique ceramic material known for its exceptional thermal properties. This #6 size nozzle features a 3/8-inch (9.5mm) orifice, providing optimal gas coverage for medium-gauge materials and precision joints. The 13N16 is engineered specifically to fit the industry-standard 9 Series (air-cooled) and 20 Series (water-cooled) TIG torch bodies, ensuring broad compatibility across various equipment setups.

Superior Durability in Confined Spaces

One of the primary failure modes for standard TIG cups is thermal shock, often resulting in cracking or shattering during use. This is particularly prevalent in confined areas or tight corners where the welding arc's heat is reflected off the workpiece and back onto the nozzle itself. The Weldcraft 13N16 Lava nozzle excels in these environments. The material's structure allows it to withstand significantly higher temperatures and thermal cycling without structural degradation. By resisting cracking, these nozzles maintain proper shielding gas flow and prevent atmospheric contamination of the weld pool, which is critical for maintaining X-ray quality welds in demanding industrial environments.

Technical Specifications and Compatibility

This product is supplied as a package of 10, ensuring that professional fabricators have an adequate supply for continuous production. The nozzle threads directly onto the collet body of compatible torches. It is essential for operators to verify they are using the correct series torch (9 or 20) as the thread pitch and diameter differ from the larger 17/18/26 series. The #6 orifice size strikes a balance between gas conservation and coverage area, making it a versatile choice for welding stainless steel, carbon steel, and aluminum alloys. By choosing genuine Weldcraft components, users ensure tight manufacturing tolerances that prevent gas leakage and thread stripping.
