OVERVIEW

Weldcraft 08N78: The Durable Choice for Tough TIG Jobs

Every TIG welder knows the frustration of hearing that distinct "tink" sound—the sound of a ceramic cup cracking just as you are in the middle of a critical pass. This often happens when you are welding in a tight corner, a deep V-groove, or inside a pipe where the heat has nowhere to go but back at your torch. Standard pink alumina cups just can't take that kind of abuse for long. That is exactly why you need the Weldcraft 08N78 Lava Nozzle in your kit. Made from a tough, heat-resistant Lava material, these nozzles are built to survive where others fail.

The #8 size (1/2 inch) is a versatile workhorse for a wide range of TIG applications, giving you excellent gas coverage whether you are walking the cup on pipe or laying down precision beads on stainless sheet. Because these nozzles are machined from Lava, they resist the thermal shock that shatters ordinary cups. This means you spend less time swapping out broken parts and more time welding. While they might cost a little more upfront than basic ceramics, the durability pays for itself by keeping you welding longer without interruption.

These nozzles are designed to fit the most common torches in the industry—the 17, 18, and 26 series. Whether you are running an air-cooled rig in the garage or a heavy-duty water-cooled setup in the shop, these cups will thread right on. This 10-pack ensures you have plenty of backups, although with the durability of Lava, you won't be burning through them nearly as fast as you're used to. Upgrade your front-end parts to Weldcraft Lava nozzles and experience the difference in durability when the heat is on.

FAQ

Lava nozzles are made from a natural stone material that offers superior resistance to thermal shock and cracking compared to standard Alumina (ceramic) nozzles, especially in high-heat or confined applications.

The 08N78 nozzle is compatible with all standard 17, 18, and 26 series TIG torches, regardless of the torch brand.

A #8 nozzle has an orifice diameter of 1/2 inch (approximately 12.7mm).

You should use a Lava nozzle if you are welding in tight corners or areas where heat is reflected back at the torch, as they are much less likely to crack than standard cups.

This product is a package of 10 nozzles.

Generally, Lava nozzles use the same standard insulators and collet bodies as standard alumina nozzles for the 17/18/26 series.

Yes, this is a genuine Weldcraft (Miller Electric) product, ensuring high quality and consistent manufacturing tolerances.

Yes, Lava nozzles are durable and can be used for walking the cup, though their primary advantage is heat resistance.
