20859 - ESAB PT-121 1.6mm Plasma Nozzle 70A

Precision Cutting with ESAB PT-121 Consumables

The ESAB 20859 1.6mm Tip is a critical component designed specifically for the heavy-duty PT-121 plasma cutting torch. In the realm of industrial metal fabrication, the quality of your consumables directly dictates the quality of your cut. This nozzle features a precision-drilled 1.6mm orifice, engineered to constrict the plasma arc effectively at amperage settings around 70 Amps. By focusing the energy density of the plasma stream, this tip allows for clean, rapid cuts through conductive metals including mild steel, stainless steel, and aluminum.

Manufactured from high-grade copper alloys, the 20859 tip offers exceptional thermal conductivity. This is vital for maintaining the structural integrity of the nozzle under the intense heat of the plasma arc. Inferior generic alternatives often suffer from rapid orifice deformation, leading to wandering arcs, excessive dross, and beveled cut edges. ESAB's OEM manufacturing standards ensure that every 20859 tip provides a consistent gas flow pattern and electrical connection, maximizing the lifespan of both the nozzle and the electrode.

For fabrication shops relying on the PT-121 torch for production cutting, consistency is key. This 1.6mm nozzle is calibrated to deliver optimal gas velocity, ensuring that molten metal is ejected efficiently from the kerf. Whether you are performing straight cuts or intricate shape cutting, relying on genuine ESAB consumables guarantees that your equipment operates within its specified parameters, protecting your torch head from damage and ensuring safety and efficiency in your operations.

Technical Excellence

The geometry of the 20859 nozzle is the result of extensive fluid dynamics research by ESAB. The internal taper and orifice length are balanced to stabilize the arc attachment point, reducing the likelihood of double-arcing which can instantly destroy a nozzle. When paired with the correct electrode and swirl baffle, this tip delivers the performance professionals expect from the PT-121 system.
