Esab 0588000438 Tig Torch Nozzle Size 10 Alumina

Product Description

The ESAB 0588000438 is a size 10 alumina ceramic nozzle designed for use with TIG welding torches. It fits the widely used 17, 18, and 26 series TIG torch bodies and serves as a direct replacement consumable for welders and welding maintenance technicians. The nozzle features a 16.0 mm orifice opening and an overall outside diameter of 5/8 inch. Alumina ceramic construction provides good heat resistance and electrical insulation at the torch cup, protecting the tungsten electrode and shielding gas flow during the welding arc. This is a single-unit replacement consumable sold individually.

This nozzle is suited for light to medium duty TIG welding applications in fabrication shops, pipe welding, and maintenance welding environments. The size 10 designation corresponds to the cup diameter and determines the shielding gas coverage area around the tungsten. It is appropriate for use on both air-cooled and compatible water-cooled 17, 18, and 26 series torch configurations where a standard alumina ceramic cup is specified. Welders and welding technicians performing routine consumable replacement will find this a straightforward swap during torch maintenance.

Installation Notes

TIG torch nozzle replacement is performed by qualified welders or welding equipment technicians. Always de-energize the welding power source and allow the torch to cool fully before handling consumables. Thread or seat the ceramic nozzle carefully onto the torch body to avoid cracking the alumina material — do not overtighten. Inspect the collet body and back cap for wear or contamination before reinstalling the nozzle.
