Superior Marking
High speed marking or scoring on mild steel, stainless steel, aluminum and other metals up to 300 inches per minute (7.5 m/min).
Creates punches or dimples for drill starts.
Variable power output lets you control width and depth of mark, score or dimple.
Optimized Design Optimized electrode design maximizes consumable life to reduce operating cost. Switch between light or heavy marking or scoring without changing consumable parts. Torch design allows fast, easy change of consumables. Contact start torch feature eliminates radio frequency noise problems. Pneumatic cap sensor provides operator safety. Outperforms powder and ink marking devices Ability to mark on wet or oily plate. No powder clogging problems; works in humid environments. |
Flexible Operation
Dual-gas torch design allows for the separation of plasma and shield gases which maximizes process flexibility.
CNC machine interface for automated system control of all functions, including active current control.
Allows customized lead lengths up to 100' (30 m).
Easily applied to any X-Y motion control system.
Use 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.
Maximum Reliability Heavy duty, chopper power supply provides 100% duty cycle. Backed by Hypertherm warranty: Two years on power supply. One year on torch. |
