37329 - ESAB PT-20/21AMX 30A Plasma Nozzle (5-Pack)

High-Precision 30 Amp Plasma Nozzles

The ESAB 37329 Nozzle is a critical consumable component designed specifically for the PT-20 and PT-21AMX series of plasma cutting torches. Engineered to operate at 30 Amperes, this nozzle is responsible for constricting the plasma arc to a high-velocity stream, enabling the precision cutting of conductive metals. The geometry of the nozzle orifice is manufactured to extremely tight tolerances, ensuring that the gas flow remains laminar and the arc energy is focused effectively on the workpiece. This level of precision is vital for maintaining a narrow kerf width and minimizing the heat-affected zone (HAZ) on thinner materials.

Constructed from high-quality copper alloy, these nozzles offer excellent thermal conductivity, allowing them to dissipate the intense heat generated during the plasma process. Proper heat management is essential to prevent the nozzle orifice from eroding or becoming misshapen, which would otherwise lead to poor cut quality, excessive dross, and an unstable arc. As an Original Equipment Manufacturer (OEM) part, the ESAB 37329 guarantees perfect compatibility with the torch head assembly, ensuring that the gas distribution ring and electrode align correctly for optimal performance.

Industrial maintenance teams and fabrication shops rely on consistent consumable performance to maintain production schedules. Using non-OEM or generic nozzles can often lead to premature failure or damage to the torch head itself. This pack contains five (5) nozzles, providing operators with the necessary inventory to perform routine maintenance without interruption. Regular inspection of the nozzle orifice is recommended; if the hole appears oval or obstructed, immediate replacement is necessary to protect the torch and ensure cut integrity. These nozzles are particularly suited for applications requiring fine detail work or when cutting thin-gauge steel, stainless steel, or aluminum where lower amperage settings are preferred.

By maintaining a stock of ESAB 37329 nozzles, facilities ensure that their PT-20 and PT-21AMX systems continue to operate at peak efficiency. The 30A rating is specifically calibrated for the drag-cutting or standoff-cutting capabilities of these specific torch models, making this a non-interchangeable part for higher amperage setups. Trust in genuine ESAB parts for reliability and safety in industrial plasma cutting environments.
