105Z45 - Weldcraft 105Z45 Lava Nozzle #7 (10-Pack)

Stop Replacing Cracked Cups: Upgrade to Lava

Every TIG welder knows the frustration of hearing that subtle "tink" sound—the sound of a ceramic cup cracking under heat stress. If you are working in tight corners, pipe roots, or confined spaces, the heat reflected back at your torch can destroy standard alumina nozzles in minutes. The Weldcraft 105Z45 Lava Nozzle #7 is your solution to this common headache. Built to take a beating, these lava nozzles are significantly tougher than standard pink ceramic cups, standing up to the abuse of high-amperage welding and rapid thermal cycling without falling apart.

This nozzle is a size #7, giving you a 7/16-inch opening that is perfect for a wide range of tungsten sizes and gas flow rates. It is designed to fit the most common torches in the industry: the air-cooled 17 and 26 series, and the water-cooled 18 series. Whether you are running a Miller Syncrowave, a Dynasty, or any other machine equipped with these standard torch bodies, this nozzle will thread right on. The lava material doesn't just resist cracking; it handles the intense heat of AC aluminum welding and heavy DC stainless work with ease.

Why Choose Lava?
While they might cost a little more upfront than basic alumina cups, lava nozzles save you money in the long run. Think about the downtime caused by stopping a weld, waiting for the torch to cool, and swapping out a broken cup. Now multiply that by a pack of 10. With the 105Z45 10-pack, you aren't just buying nozzles; you are buying continuous arc time. These nozzles are machined for precision, ensuring a smooth gas flow that keeps your puddle clean and your tungsten protected. If you are tired of fragile consumables slowing you down, make the switch to Weldcraft Lava nozzles and keep burning rod while others are swapping parts.
