0558004358 - ESAB PT-35 Plasma Torch Nozzle B (35-50A) - 5 Pack

Technical Overview of ESAB PT-35 Nozzle B

The ESAB 0558004358 is a specific replacement nozzle designed for the PT-35 plasma cutting torch, commonly found on ESAB PowerCut series machines (such as the PowerCut 650). This component is identified as Nozzle "B", which indicates its calibration for a specific amperage range, specifically 35 to 50 Amps. The nozzle plays a critical role in the plasma cutting process by constricting the gas flow to focus the plasma arc, thereby determining the cut width and quality.

Manufactured to precise OEM tolerances, this nozzle ensures that the electrode and gas flow are perfectly aligned. The orifice diameter is engineered to handle the thermal load of 35-50A currents without rapid degradation, provided that clean, dry air is used. The use of high-quality tellurium copper or similar conductive alloys in its construction aids in rapid heat transfer, pulling thermal energy away from the orifice edge to extend consumable life. This pack contains five (5) nozzles, allowing for efficient inventory management in industrial MRO environments.

Proper selection of the nozzle size is paramount for system performance. Using a Type B nozzle at amperages significantly lower or higher than the rated 35-50A range can lead to arc instability or immediate damage to the orifice. This product is a direct replacement part, ensuring full compatibility with the torch head geometry and retaining cap threads of the PT-35 assembly.
