Esab 0365310044 Tig Torch Nozzle Size 4 0.25 Inch

Product Description

The ESAB 0365310044 is a Size 4 TIG torch nozzle designed to direct and shape the shielding gas envelope around the tungsten electrode during gas tungsten arc welding (GTAW). The nozzle features a 0.25 inch (6.0 mm) orifice opening, which suits standard-coverage applications on light to medium material thicknesses. It is a consumable component that seats into the torch body and is replaced as part of routine torch maintenance. Licensed welders, pipe fitters, and fabricators working with GTAW equipment install and swap these nozzles in shop and field settings.

This nozzle is rated for use with the HW20 and 20A torch models. Those torches are commonly found in light industrial, aerospace, and precision fabrication environments where clean, controlled welds are required on steel, stainless, aluminum, and other alloys. The Size 4 designation is a standard industry nozzle sizing convention and indicates the nozzle orifice is 4 sixteenths of an inch (0.25 inch) in diameter. This size is well-suited for lower amperage GTAW work with smaller tungsten diameters.

Installation Notes

TIG torch nozzles are installed and replaced by qualified welders or welding technicians. Always power down the welding machine and allow the torch to cool completely before removing or installing a nozzle. Thread or seat the nozzle firmly by hand according to torch manufacturer guidelines — do not use tools that may crack ceramic or glass nozzle materials. Inspect the collet, collet body, and back cap for wear at each nozzle change to maintain consistent arc performance.
