21597 - ESAB PT-25 Plasma Nozzle 100A - 5 Pack

High-Performance Consumables for Industrial Plasma Cutting

The ESAB 21597 PT-25 Nozzle is a critical component designed for the PT-25 plasma cutting torch, engineered to handle the thermal and electrical demands of 100-amp operations. In plasma cutting systems, the nozzle plays a pivotal role in constricting the plasma arc, increasing its energy density and velocity to effectively melt and blow away metal. This specific nozzle features a precision-machined orifice that ensures the arc remains focused and stable, which is essential for achieving high-quality cuts with minimal bevel and dross.

Manufactured to ESAB's rigorous standards, this nozzle is constructed from a high-grade copper alloy. This material selection is vital for thermal management; as the plasma arc passes through the nozzle, significant heat is generated. The superior thermal conductivity of the copper helps dissipate this heat, preventing premature failure of the nozzle and protecting the torch head. The 100A rating indicates that the orifice diameter is optimized for the gas flow and current density typical of 100-amp cutting parameters. Using a nozzle with the correct amperage rating is crucial; a nozzle designed for lower amperage will overheat and degrade quickly if used at 100A, while a nozzle designed for higher amperage will result in a wandering arc and poor cut quality.

This product is supplied as a pack of five, addressing the consumable nature of plasma nozzles. In high-volume industrial environments, nozzle wear is inevitable due to the extreme heat and the erosion caused by the plasma gas. Regular replacement is necessary to maintain process reliability. Signs of wear, such as an out-of-round orifice or internal pitting, can lead to deteriorating cut quality and potential damage to the electrode. By maintaining a stock of these 21597 nozzles, facility managers and operators can ensure minimal downtime and consistent production quality.

Compatibility is strictly for the ESAB PT-25 torch series. Users should verify their torch model before installation to ensure proper fitment and gas sealing. The 21597 nozzle integrates seamlessly with the PT-25's retaining cap and electrode system, completing the electrical circuit and gas flow path required for efficient plasma generation.
