Nozzle 420279 For Hypertherm XPR300 Plasma Cutting Torch Consumables (300A Mild Steel)

Nozzle 420279 For Hypertherm XPR300 Plasma Cutting Torch Consumables (300A Mild Steel)

The nozzle is the critical final component in the plasma torch consumable stack that determines cut quality at maximum output. The HALANSM 420279 is the 300A mild-steel nozzle for the XPR300 system: it compresses the plasma arc column and directs the high-velocity gas stream to deliver clean, square-cut edges and minimal dross on the thickest mild steel plates.

Key Features

• Heavy-Duty Silver Plating: Advanced silver-plating technology over a tough chrome-zirconium copper base maximizes electrical conductivity, prevents oxidation, and withstands the extreme thermal cycling of 300-amp operations.

  
  

• Ultra-Precise Orifice: The internal bore is machined to exact OEM specifications to ensure a perfectly stable and consistent plasma jet, which is non-negotiable for maintaining cut quality on 20mm+ steel.

  
  

• Optimized Gas Flow Path: Specifically engineered geometry ensures perfect alignment with the 300A swirl ring and shield cap, creating optimal laminar gas flow for efficient arc constriction and debris removal.

  
  

• Perfect Drop-In Fit: Precision-machined external threads and exact dimensional tolerances ensure a seamless, hassle-free replacement for Hypertherm 420279 without requiring any modifications.
