OVERVIEW

High-Performance Lava Nozzle for Micro TIG Applications

The Weldcraft 50N04 is a specialized TIG welding nozzle designed for the precision requirements of the WP-50 and WP-50V Micro TIG torches. Manufactured from premium Lava material, this nozzle is engineered to withstand the intense thermal conditions often encountered in confined space welding. Unlike standard alumina ceramic cups, Lava nozzles offer superior resistance to reflected heat, preventing cracking and failure when welding in deep grooves, corners, or restricted access areas where the arc heat bounces back onto the torch front end.

This specific model features a #4 orifice (1/4 inch) and comes equipped with integrated screens. These screens function similarly to a gas lens, smoothing the shielding gas flow to reduce turbulence and improve weld pool protection. This is particularly critical in micro-welding applications where even minor gas disturbances can lead to porosity or oxidation. The 50N04 is an essential consumable for industries requiring high-precision joins, such as aerospace, tool and die repair, and medical device manufacturing.

Supplied in a pack of 10, these nozzles ensure that operators have a ready supply of consumables for continuous production. The threaded design ensures a secure fit onto the 180-degree or flex heads of the 50-series torches, maintaining proper alignment and gas seal. By combining high-heat durability with enhanced gas diffusion, the Weldcraft 50N04 optimizes the performance of Micro TIG setups.

FAQ

The 50N04 is designed specifically for Weldcraft WP-50 and WP-50V Micro TIG torches.

This nozzle is made of Lava, a material known for high heat resistance and durability against reflected heat.

It includes integrated screens that function similarly to a gas lens by smoothing out the gas flow.

It is a #4 size nozzle, which corresponds to a 1/4 inch (6.4mm) orifice diameter.

Lava nozzles handle reflected heat better than standard alumina, making them ideal for welding in tight corners or confined spaces.

The Weldcraft 50N04 is sold in a package of 10.

The WP-50 series torches typically thread the nozzle directly onto the torch body or a specific insulator setup; check your torch manual, but this is the standard cup for that series.

Yes, provided the WP-50 torch is rated for the amperage and duty cycle required for your AC application.
