OVERVIEW

Technical Overview of the Hypertherm 420261 XPR Nozzle

The Hypertherm 420261 is a high-performance plasma cutting nozzle engineered specifically for the XPR170™ and XPR300™ X-Definition™ plasma systems. This consumable is rated for 170 Amps and is metallurgically optimized for processing mild steel. As a critical component of the plasma torch assembly, the nozzle constricts the plasma arc to increase energy density and velocity, directly influencing the cut quality, kerf width, and angularity.

Utilizing Hypertherm's advanced manufacturing techniques, this nozzle features precise orifice geometry that aligns perfectly with the electrode and swirl ring to maintain a stable, centered arc. This alignment is essential for achieving X-Definition class cuts, which are characterized by ISO range 2 or 3 cut angularity on mild steel. The 420261 nozzle is designed to handle the high thermal loads associated with 170A operation, utilizing high-purity copper to facilitate rapid heat transfer to the torch cooling fluid (coolant). This thermal management prevents orifice erosion and extends the service life of the consumable.

In automated cutting environments, consistency is paramount. The 420261 nozzle ensures repeatable performance from the first pierce to the end of its life, supporting features like True Hole® technology where applicable. It functions within the specific gas mixing protocols of the XPR system, ensuring that the shielding and plasma gases interact correctly to protect the cut edge and the nozzle itself. Operators and maintenance personnel should verify that this nozzle is paired with the correct shield, electrode, and swirl ring for 170A mild steel processes to prevent premature failure or damage to the torch head.

FAQ

The 420261 nozzle is designed for use with Hypertherm XPR170 and XPR300 plasma cutting systems.

This nozzle is rated for 170 Amps.

This specific part number (420261) is optimized for cutting Mild Steel.

Yes, this is a genuine Original Equipment Manufacturer (OEM) part manufactured by Hypertherm.

The nozzle should be replaced when the orifice becomes out-of-round, notched, or significantly worn, which will cause cut quality (angularity and dross) to deteriorate.

No, this nozzle is specifically designed for mild steel. You should use the appropriate nozzle part number designated for stainless steel or aluminum for those materials to ensure proper cut quality.

Yes, when used as part of a complete XPR system with compatible software and parameters, this nozzle supports Hypertherm's True Hole technology for bolt-ready holes.

Using a nozzle at an amperage significantly higher than its rating will destroy it quickly. Using it at a much lower amperage will result in a soft arc and poor cut quality.
