Abstract
The invention relates to a water-vapor plasma torch () for cutting a workpiece (), comprising a feed line () for a liquid (), a heating device (), and an evaporator () for forming a gas () from the liquid (), a cathode () detachably connected to a movably mounted piston rod (), and a nozzle () with an outlet opening () for the gas (), as well as to a wear-detection and process-control method to be used with such a water-vapor plasma torch (). To create such a water-vapor plasma torch () including wearing-part detection, at least one temperature sensor () is arranged within the piston rod (), said temperature sensor being connected to a control unit (), so that a wear of the cathode () and the nozzle () can be concluded from the temperature values detected, and that the control of the water-vapor plasma cutting process is influenceable.
