53N23 - ESAB 53N23 #3 Alumina Nozzle for HW-24 TIG Torch

Technical Overview of the ESAB 53N23 Alumina Cup

The ESAB 53N23 is a specialized alumina ceramic nozzle designed for the HW-24 and WP-24 series of TIG welding torches. These torches are categorized as 'micro' or compact TIG torches, engineered specifically for welding in confined spaces where standard 17 or 26 series torches cannot reach. The 53N23 cup features a #3 orifice, measuring approximately 0.165 inches (nominally 3/16 inch), which provides a focused stream of shielding gas ideal for fine detail work and low-amperage applications.

Manufactured from high-grade alumina oxide, this ceramic cup exhibits excellent thermal shock resistance and dielectric strength. In TIG welding, the nozzle is subjected to intense radiant heat from the arc as well as rapid cooling cycles. The alumina composition ensures the cup maintains its structural integrity without cracking or degrading under these harsh conditions. The standard thread design ensures a secure fit onto the collet body of the HW-24 torch, preventing gas leakage and ensuring laminar flow is directed precisely at the tungsten electrode and weld pool.

This nozzle is an essential consumable for precision fabrication industries, including aerospace, automotive exhaust manufacturing, and tool and die repair. Its small profile allows the welder to maintain a proper torch angle and arc length even in recesses or corners. The 53N23 is compatible with standard gas-cooled and water-cooled 24-series torch setups, making it a versatile component for maintenance and repair operations requiring high-precision welding capabilities.
