105Z61 - Weldcraft 105Z61 Long Lava TIG Nozzle #7L (10-Pack)

Technical Overview of the Weldcraft 105Z61 Long Lava Nozzle

The Weldcraft 105Z61 is a specialized TIG welding nozzle designed for applications requiring extended reach and superior thermal durability. Classified as a #7L (Long) nozzle, it features a 7/16-inch (11mm) orifice diameter. This specific geometry is engineered to allow welders to access deep joints, corners, and confined spaces that standard length nozzles cannot reach effectively. The elongated design not only improves physical access but also helps in maintaining proper gas coverage in restricted areas where turbulence might otherwise be an issue.

A defining characteristic of this nozzle is its construction material: Lava. Unlike standard pink Alumina Oxide nozzles, Lava nozzles are machined from a natural stone material and then fired. This manufacturing process results in a consumable with exceptional resistance to thermal shock. In welding scenarios where the nozzle is subjected to intense reflected heat—such as welding inside a pipe or a tight corner—standard alumina cups are prone to cracking and failure. The Weldcraft 105Z61 Lava nozzle withstands these harsh conditions significantly better, maintaining structural integrity and reducing the frequency of consumable replacement.

This nozzle is fully compatible with industry-standard 17, 18, and 26 series TIG torches, making it a versatile addition to any professional welder's toolkit. It threads directly onto the collet body of these torch series. The 105Z61 is an essential component for precision TIG welding where visibility and access are compromised, ensuring that the shielding gas is directed precisely where it is needed without the bulk of a standard cup obstructing the view or the arc.

Supplied in a pack of 10, these nozzles ensure that production lines and fabrication shops have a steady supply of high-performance consumables. The consistency in manufacturing by Weldcraft guarantees that each nozzle threads correctly and provides a consistent gas flow pattern, which is critical for maintaining weld quality in high-specification environments.
