13N19 - Weldcraft 13N19 Lava TIG Nozzle Cup #10 (5/8 Inch) - 10 Pack

Genuine Weldcraft 13N19 Lava Cups for Series 9 & 20 Torches

Upgrade your TIG welding setup with the Weldcraft 13N19 Lava TIG Nozzle, available in a value-packed bag of 10. These size #10 cups provide a generous 5/8-inch opening, offering excellent gas coverage for a variety of welding joints. Designed as a direct replacement for standard consumables, they fit perfectly on all 9 and 20 series TIG torches, including air-cooled and water-cooled models commonly used in the industry.

The primary advantage of choosing the 13N19 Lava nozzle over traditional pink alumina cups is durability. TIG welding generates intense heat, and rapid heating and cooling cycles can cause standard ceramics to crack or shatter. Lava material is inherently tougher and more resistant to this thermal shock. This resilience means the nozzle stays intact longer, even in demanding shop environments where torches might be handled roughly or subjected to high reflective heat in tight corners.

For professional welders, consistency is key. A cracked nozzle can disrupt gas flow, leading to turbulence, porosity, and weld contamination. By using genuine Weldcraft Lava nozzles, you ensure a stable laminar flow of shielding gas, protecting your tungsten and the weld pool effectively. This reliability makes them a favorite among pipe welders and fabricators who cannot afford to stop mid-weld to replace a broken cup.

Investing in high-quality consumables like the Weldcraft 13N19 is an investment in productivity. Although the upfront cost is marginally higher than standard ceramics, the reduction in replacement frequency and the assurance of quality make them the smarter choice for serious welders. Keep your torch running cool and your welds clean with these heavy-duty Lava nozzles.
