Mining fabrication, structural steel processing, wear plate and clad plate cutting - the XPR460 is specified when maximum pierce capacity, sustained throughput on thick material, and consistent cut quality under continuous production load are all required at the same time.
Available on both the Plazmax CutAce and CutPro, the XPR460 is configured with the VWI (Vented Water Injection) console as standard on all Plazmax machines.
Pierce capacity determines whether your machine can initiate a cut mid-plate without edge starting - the number that governs nest cutting and full-sheet processing. Cut capacity (severance) is the maximum thickness the system can push through. For operations processing heavy plate from a nest, the pierce figures are what matter. For project work where edge starting is acceptable, severance tells you the true upper limit of the system.
For operations processing plate continuously from a nest, production pierce capacity is the number that matters most. For project-based fabrication where edge starting is acceptable, the severance figure gives a better picture of the system's upper limit.

If your operation regularly cuts 40-50mm mild steel plate, the question is not just whether the system can pierce it - both the XPR300 and XPR460 can. The question is how fast it cuts that material in production, and what that means for throughput across a full shift.
At 40mm mild steel, the XPR460 runs at 1,300 mm/min. The XPR300 runs the same thickness at 940 mm/min. That is a 38% speed advantage on a thickness both systems handle comfortably. At 50mm, the XPR460 runs at 850 mm/min against the XPR300's 560 mm/min - a 52% speed advantage. On a machine running 8-10 hours a day cutting structural plate in that thickness range, the difference in parts per shift is significant.
For operations where 40-50mm is the bread-and-butter thickness rather than the occasional job, the XPR460 is the more productive specification - independent of whether the XPR300 could technically do the work.
On 40mm plate, a 45° bevel requires the plasma arc to travel through approximately 57mm of material at the torch angle. At 50°, that increases to around 62mm. The cut speed the system achieves through that effective thickness - not the nominal plate thickness - is what determines your bevel production rate.
Running bevel cuts on 40mm structural plate with an XPR460 means the system is operating well within its capacity on the effective cut path. Running the same bevel on an XPR300 puts it at or near its upper limit, with cut speeds dropping to where bevel quality and throughput are both compromised. For fabrication shops doing consistent weld-prep bevel work on plate 35mm and above, the XPR460 is the correct specification.
The XPR460 delivers the same X-Definition® process as the XPR170 and XPR300 - consistent ISO 9013 cut quality on mild steel, improved stainless steel cut quality via the VWI water injection shield, and clean aluminium edges. At 460 amps, it maintains that quality at the higher cut speeds the amperage enables, without the edge degradation that occurs when a lower-powered system is pushed to its limit on thick material.
The XPR460 includes Hypertherm's Arc Response Technology®, which monitors the cutting process and automatically intervenes to protect the torch and consumables. Automatic ramp-down error protection prevents electrode blowouts during over-stretched arcs. Automatic torch protection shuts down before catastrophic failure at end-of-electrode-life. On a machine running heavy plate continuously, these protections directly reduce unplanned downtime and consumable waste.
The XPR460 is available as a power source option on both the Plazmax CutAce and Plazmax CutPro. All Plazmax machines are delivered with turnkey installation, operator training, and full NZ-based technical support. As the manufacturer, we commission the XPR460 integration and can support both the machine and the power source from a single point of contact in New Zealand.
As an authorised Hypertherm OEM Channel Partner, Plazmax supplies genuine XPR460 consumables and replacement parts. Consumables are process-specific - the correct combination of electrode, nozzle, shield, and retaining cap depends on the material and amperage being run.
