13N18 - Weldcraft 13N18 Lava TIG Cup Size 8 (10-Pack)

Tough Cups for Tight Spots: Weldcraft 13N18 Lava Nozzles

Every TIG welder knows the frustration of a cracked cup right in the middle of a critical pass. When you are welding in a tight corner or walking the cup on a pipe, the heat has nowhere to go but back at your torch. That is where standard pink alumina cups often fail—they just can't take the thermal shock. Enter the Weldcraft 13N18 Lava TIG Nozzle. Built from a specialized lava material, these cups are the heavy-duty alternative designed to stand up to the abuse that shatters ordinary nozzles.

The 13N18 is a Size #8 cup, giving you a 1/2-inch opening that provides excellent gas coverage for a clean, oxidation-free weld. It is designed to fit your standard 9 Series air-cooled torches and 20 Series water-cooled torches. Because it is a genuine Weldcraft product, you don't have to worry about cross-threading or loose fits; it screws on tight and stays put, letting you focus on your puddle control rather than your equipment.

Why choose Lava? It comes down to durability and cost-savings over time. While they might cost a little more upfront than basic ceramic cups, lava nozzles resist cracking when exposed to high reflected heat. This makes them the welder's choice for confined space work, root passes in pipe welding, and any application where the torch gets hot and stays hot. A cracked cup can suck in atmosphere and ruin a weld, leading to costly rework. Using a lava nozzle is cheap insurance against porosity caused by equipment failure.

This package includes 10 nozzles, ensuring you have plenty of backups in your toolbox. Whether you are a professional pipe welder, a fabricator in a job shop, or a serious hobbyist demanding the best, the Weldcraft 13N18 Lava Cup pack keeps you welding longer. Don't let a fragile cup slow you down—upgrade to the thermal resistance of lava and keep your arc burning.
