13N15 - Weldcraft 13N15 Lava TIG Nozzle #5 (5/16") - 10 Pack

High-Performance Heat Resistance with Weldcraft Lava Nozzles

The Weldcraft 13N15 Lava TIG Nozzle is a premium consumable designed for professional TIG welders who demand durability and reliability in challenging environments. Sized as a #5 cup (5/16-inch orifice), this nozzle provides focused shielding gas coverage ideal for precision welding on thinner gauge materials or tight joints. Unlike standard pink alumina oxide nozzles, this product is manufactured from a specialized "Lava" material, a fired ceramic known for its exceptional ability to withstand thermal shock and high temperatures without fracturing.

Superior Durability in Confined Spaces

One of the primary challenges in TIG welding is managing heat buildup, not just in the base metal, but in the torch consumables themselves. When welding in confined areas—such as inside pipe manifolds, roll cages, or deep corners—heat is often reflected off the workpiece and back onto the nozzle. Standard alumina cups can become brittle and crack under this intense, localized thermal stress. The Weldcraft 13N15 Lava nozzle is engineered specifically to solve this problem. Its robust material composition allows it to absorb and dissipate reflected heat far more effectively, significantly reducing the frequency of cracked cups and downtime associated with replacing broken consumables.

Compatibility and Precision

This nozzle is designed to fit 9 Series (air-cooled) and 20 Series (water-cooled) TIG torches, which are industry standards for precision fabrication. Whether you are using a Weldcraft, Miller, Lincoln, or CK Worldwide torch body in these series, the 13N15 offers a perfect thread fit onto your collet body or gas lens. The #5 size is particularly versatile, offering a balance between gas conservation and adequate coverage for tungsten electrodes up to 3/32" (though often used with smaller diameters like 1/16" or 0.040").

Genuine Weldcraft Quality

As a genuine Weldcraft product (now under the Miller Electric umbrella), these nozzles are manufactured to strict tolerances. This ensures consistent gas flow characteristics, which is critical for maintaining a stable arc and preventing weld contamination. Cheap generic nozzles often have irregular bore surfaces that can cause turbulence in the shielding gas stream; Weldcraft Lava nozzles provide the smooth laminar flow necessary for X-ray quality welds. Supplied in a convenient pack of 10, this product ensures your welding cabinet is stocked for long production runs.
