21923 - ESAB PT-24 100A Plasma Cutting Nozzle

High-Performance Cutting with the ESAB 21923 Nozzle

The ESAB 21923 Nozzle is a precision-engineered consumable designed exclusively for the PT-24 plasma cutting torch. Rated for 100 Amps, this nozzle is built to facilitate high-energy plasma cutting operations, delivering the thermal density required to slice through thick conductive metals with accuracy. For industrial facilities and fabrication centers utilizing ESAB plasma systems, maintaining the integrity of the torch assembly with genuine OEM parts is critical for operational efficiency and cut quality.

The primary function of the plasma nozzle is to constrict the ionized gas stream, focusing the plasma arc into a high-velocity column. The ESAB 21923 features a meticulously machined orifice that ensures this arc remains stable and centered. A stable arc is essential for achieving narrow kerf widths, square edges, and minimal heat-affected zones (HAZ). Over time, the intense heat and high-velocity gas erode the nozzle bore, causing it to become oval-shaped. This degradation leads to wandering arcs and poor cut quality. Replacing the nozzle with a fresh 21923 unit restores the torch's ability to produce clean, dross-free cuts.

Constructed from high-quality copper alloy, the 21923 nozzle offers superior thermal conductivity. This material property allows the component to dissipate the extreme heat generated during 100A cutting processes effectively. Efficient heat management prevents premature melting or deformation of the nozzle tip, significantly extending its service life compared to inferior aftermarket alternatives. Furthermore, the precise dimensions of the nozzle ensure proper gas flow dynamics and electrical isolation within the torch head, protecting the electrode and swirl ring from damage.

For procurement and maintenance teams, the ESAB 21923 represents reliability. In automated or mechanized cutting environments where the PT-24 is often deployed, consistency is key to maintaining production schedules. Using genuine ESAB consumables eliminates the variability found in generic parts, ensuring that your equipment operates within its design specifications. Whether cutting mild steel, stainless steel, or aluminum, this 100 Amp nozzle provides the durability and performance necessary for demanding industrial applications.
