Nozzle 420270 For Hypertherm XPR300 Plasma Cutting Torch Consumables 220A
The nozzle is the component that decides how tight and repeatable your plasma arc actually is. 420270 is the 220A mild-steel nozzle in the XPR consumable stack: it compresses the arc column and directs the high-velocity gas stream so the cut edge stays straight and the dross stays thin—especially important once you're through 10–25mm+ plate.
Key Features
Precision-Machined Orifice: Bore finished to OEM tolerance so the plasma jet leaves consistently; critical for ISO-range cut quality on thicker mild steel.
High Thermal Conductivity: Copper alloy body pulls heat away from the arc zone, keeping nozzle shape stable across long, high-current runs.
O₂/Air Mild Steel Geometry: Matched to the 220A shield/swirl-ring/electrode stack(420273 / 420406 / 420276)so gas sealing and flow alignment stay correct.
Drop-In Fit: Threads, length, and outer profile follow the Hypertherm 420270 envelope—no filing, no shimming.
