ArcWriter plasma marking system

The Hypertherm ArcWriter® is a dual gas plasma marking, scoring and punching system that’s ideal for labeling parts, creating dimples for drill starts, and any other marking, scoring or punching – anywhere you need to create temporary or permanent identification marks on metal surfaces.   Its heavy-duty power supply delivers 100% duty cycle operation for heavy-duty industrial applications.



System information


Superior marking capability

  • Designed for high speed marking or scoring on mild steel, stainless steel, aluminum, and other metals at up to 7.5 m/min (300 inches per minute).
  • Creates perfect punches or dimples for drill starts
  • Variable power output lets you easily control width and depth of mark, score or dimple

Outperforms powder and ink marking devices

  • Able to reliably mark on wet or oily metal surfaces
  • Works in humid environments – no powder clogging problems
  • Lets you switch between light or heavy marking or scoring without changing parts
  • Optimized electrode design maximizes consumable life to reduce operating cost

Flexible process operation

  • Dual-gas torch design maximizes process flexibility
  • CNC machine interface allows automated system control of all functions, including active current control
  • Easily applied to any X-Y motion control system
  • Can be used as a stand-alone system or mount alongside plasma cutting tools on the same torch station
  • Divided arc voltage signals available for active-torch height control
