13N17 - Weldcraft 13N17 Lava TIG Nozzle #7 (7/16") - 10 Pack

Heavy-Duty Lava TIG Cups for 9 & 20 Series Torches

Upgrade your TIG welding arsenal with the Weldcraft 13N17 Lava Nozzle, a robust solution for welders facing demanding heat conditions. Sold in a convenient package of 10, these #7 size cups are an essential component for any welder using the popular 9 series air-cooled or 20 series water-cooled torches. While standard pink alumina cups are sufficient for general purpose work, they often fail when pushed to the limit. The 13N17 Lava cup is built to withstand the abuse that standard ceramics cannot.

The secret to the 13N17's performance lies in its material composition. Lava nozzles are machined and fired to create a dense, heat-resistant structure that excels in "hot" applications. If you frequently weld in deep grooves, corners, or restricted areas, you know that the reflected heat can cause standard cups to snap or shatter unexpectedly. These Lava nozzles are specifically formulated to resist this thermal shock, reducing the frequency of replacements and keeping you under the hood welding rather than stopping to change out broken parts.

With a 7/16" (approx. 11mm) bore, the #7 size is a versatile choice for medium-amperage applications, offering excellent shielding gas coverage for stainless steel, aluminum, and mild steel welding. The nozzle threads securely onto your torch's collet body, ensuring a leak-free connection that promotes stable arc starts and clean weld puddles. Whether you are in aerospace, motorsports fabrication, or general repair, the reliability of Weldcraft's Lava series helps lower your overall labor costs by minimizing downtime associated with consumable failure.

Why Choose Lava?

• Reduced Downtime: Fewer cracked cups means more arc-on time.
• Cost Effective: Although the initial unit cost may be higher than alumina, the extended lifespan offers better long-term value.
• Versatile Application: Perfect for both intricate, low-amp work and higher-heat confined space welding.
