0441452003 - ESAB 3.2mm (1/8") Gas Lens for TXH TIG Torches

Precision Gas Shielding for High-Quality TIG Welding

The ESAB Gas Lens 1/8" (Part Number 0441452003) is a critical consumable designed to elevate the performance of ESAB TXH series TIG torches. Unlike standard collet bodies which can create turbulent gas flow, this gas lens utilizes a multi-layer fine mesh screen to rectify the shielding gas into a laminar column. This coherent stream of gas provides superior coverage over the weld pool, significantly reducing the risk of atmospheric contamination, oxidation, and porosity, which is particularly vital when welding reactive metals like titanium or stainless steel.

Engineering for precision, this component is sized specifically for 3.2mm (1/8-inch) tungsten electrodes. By stabilizing the gas flow, the lens allows the operator to extend the tungsten electrode further past the nozzle cup—often up to an inch depending on conditions—without compromising the protective shield. This capability is essential for industrial applications requiring deep joint access or welding in complex geometries where standard nozzle configurations would obstruct the welder's view or fail to provide adequate shielding.

Manufactured to ESAB's rigorous standards, the 0441452003 gas lens ensures consistent electrical conductivity and thermal management within the torch head. It is an indispensable upgrade for fabrication environments prioritizing weld aesthetics and metallurgical integrity.
