The ESAB 21442 Nozzle is a critical consumable component engineered specifically for the PT-251 plasma cutting torch. Designed to meet the rigorous demands of industrial fabrication environments, this nozzle features a precision-drilled .093-inch orifice, optimized for cutting applications requiring 150 Amperes of current. As a genuine OEM part, it guarantees strict adherence to ESAB's manufacturing tolerances, ensuring seamless compatibility with the torch head and proper alignment with the electrode and swirl baffle.
In plasma cutting systems, the nozzle plays a vital role in constricting the ionized gas stream to create a high-energy density arc. The 21442 nozzle is manufactured from a high-conductivity copper alloy, which effectively dissipates the intense heat generated during the 150A cutting process. This thermal management is essential for preventing premature erosion of the orifice, which can lead to poor cut quality, increased bevel angles, and excessive dross formation. By maintaining the integrity of the arc column, this nozzle supports consistent severance and precision cutting of heavy-gauge conductive metals.
Procurement professionals and facility managers should note that the PT-251 torch is often utilized in mechanized or heavy-duty handheld applications where downtime must be minimized. Using genuine ESAB consumables like the 21442 nozzle reduces the frequency of changeovers caused by inferior aftermarket parts. The consistent geometry of the .093 orifice ensures that gas flow dynamics remain stable, protecting the torch body from damage and ensuring that the plasma system operates within its specified duty cycle. This part is sold individually and is a direct replacement for worn or damaged nozzles in your existing inventory.
