220646 - Hypertherm HPR130XD 130A Mild Steel Bevel Nozzle

Technical Overview of the Hypertherm 220646 Nozzle

The Hypertherm 220646 Nozzle is a specialized plasma cutting consumable engineered specifically for high-precision beveling applications. Rated for 130 Amps, this nozzle is designed to function seamlessly with the HyPerformance® HPR130XD®, HPR260XD®, HPR400, and HPR800XD® plasma systems. It is strictly calibrated for use on mild steel, ensuring that industrial fabricators achieve the highest possible edge quality during complex bevel cuts. As a critical component of the torch assembly, the nozzle constricts the plasma arc to generate the energy density required for clean, fast cuts.

This component utilizes Hypertherm's proprietary Conical Flow™ technology. This design innovation increases the arc energy density, which directly translates to superior cut quality with significantly reduced dross levels. By focusing the plasma stream more effectively, the 220646 nozzle allows for tighter tolerances and reduced secondary processing operations. The internal geometry of the nozzle is manufactured to precise standards to align the electrode and water tube, facilitating optimal cooling fluid flow. Efficient cooling is paramount in high-amperage plasma cutting to prevent premature failure of the consumable and to maintain consistent arc stability over long production runs.

In industrial environments such as shipbuilding, pipeline construction, and heavy metal fabrication, the reliability of the plasma system is contingent on the quality of the consumables. The 220646 is manufactured in the United States to strict OEM specifications. Using genuine Hypertherm parts like this nozzle ensures that the HPR system operates within its designed parameters, protecting the torch head from damage caused by mismatched or inferior generic consumables. The nozzle's copper construction provides excellent thermal conductivity, further aiding in heat management during the intense thermal cycles of 130A bevel cutting.

Installation of the 220646 is straightforward, fitting into the standard consumable stack-up for HPR XD torches configured for beveling. It is essential for operators to verify that the system is set to the correct amperage and gas flow settings for mild steel beveling to maximize the lifespan of this nozzle. Regular inspection of the nozzle orifice for wear or ovalization is recommended to maintain cut angularity and edge finish.
