OVERVIEW

Reliable TIG Consumables for Demanding Jobs

Keep your TIG torch performing at its peak with the Weldcraft 13N15 Lava Nozzle #5. Sold in a cost-effective package of 10, these nozzles are an essential upgrade for welders experiencing frequent cup breakage. While standard alumina cups are sufficient for general bench work, they often fail when pushed to the limit in high-amperage applications or tight quarters. The 13N15 is crafted from a distinct Lava ceramic material, easily identifiable by its brownish hue, which offers superior resistance to the abuse of industrial welding environments.

Why Choose Lava Over Alumina?

For the professional fabricator, time is money. Stopping a weld to replace a cracked nozzle breaks your rhythm and delays production. The Lava material used in the 13N15 is formulated to resist "thermal shock"—the rapid expansion and contraction caused by instant temperature changes. This makes these nozzles the go-to choice for applications where the torch head gets extremely hot, such as AC aluminum welding at the upper limits of a 20 series torch, or DC welding in restricted access areas where heat has nowhere to escape. By investing in Lava nozzles, you reduce consumable waste and keep your arc on time higher.

Perfect Fit for 9 and 20 Series Torches

The 13N15 is a standard front-end part for the popular "pencil" style torches. It fits:

  • 9 Series: The compact air-cooled torches used for light-duty and intricate work.
  • 20 Series: The compact water-cooled torches used for higher amperage precision work.
  • 25 Series: Water-cooled pencil torches.

The #5 size (5/16 inch / 8mm) is a staple in any TIG kit, offering a tight gas column that allows for good visibility of the puddle and tungsten. It threads directly onto standard 13N-series collet bodies and 45V-series gas lenses compatible with these torch models.

Stock Up and Save

Welders Supply understands that running out of consumables is not an option in a busy shop. This 10-pack ensures you have plenty of backups on hand. Whether you are an aerospace welder, a motorsports fabricator, or a pipe welder working on root passes, the Weldcraft 13N15 delivers the consistency and durability you need to lay down perfect beads every time. Trust in the brand that defined TIG welding standards—Weldcraft.

FAQ

Lava nozzles are made from a fired ceramic material that is much more resistant to thermal shock and cracking than standard Alumina Oxide (pink) nozzles. They are specifically designed to withstand high reflected heat in confined spaces.

The 13N15 fits all 9 Series (air-cooled) and 20 Series (water-cooled) TIG torches, as well as 25 Series torches. It is not compatible with 17, 18, or 26 series torches.

A #5 cup has an inside bore diameter of 5/16 of an inch, or approximately 8 millimeters.

This product is sold as a package containing 10 individual Weldcraft 13N15 Lava nozzles.

No, this nozzle threads onto the standard collet bodies (13N series) used with 9 and 20 series torches. It also fits certain gas lenses designed for these torches.

Yes, you can walk the cup with a #5 nozzle, although it is quite small. The Lava material is durable enough to withstand the friction and heat associated with the technique.

The brown color is characteristic of the Lava ceramic material, distinguishing it from the pink Alumina nozzles.

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