Nozzle 420234 is the 50A orifice component for Hypertherm XPR300/XPR170 torches operating on mild steel with O₂/Air gas. Its micro-precision bore focuses the plasma arc and gas column into a tight, stable jet—so you get squarer edges, less dross, and slower nozzle wear. Machined from high-conductivity copper with a smooth internal finish, it drops in exactly where Hypertherm 420234 sits.

Nozzle 420234 For Hypertherm XPR300 Plasma Cutting Torch Consumables 50A
The nozzle is the component that decides how tight your plasma arc actually is. 420234 is the 50A 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.
Key Features
Precision-Machined Orifice： Bore is finished to OEM tolerance so the plasma jet leaves the torch consistently—critical for ISO-range cut quality on thin-to-mid plate.
High Thermal Conductivity： Copper alloy body pulls heat away from the arc zone, keeping the nozzle shape stable and extending usable life between changes.
O₂/Air Mild Steel Geometry： Matched to the 50A shield/electrode/swirl-ring stack so gas sealing and flow alignment stay correct across long runs.
Drop-In Fit： Threads, length, and outer profile follow the Hypertherm 420234 envelope—no filing, no shimming, no guesswork.
