Abstract
A program controlled metal cutting torch includes a torch height control system that utilizes a vibration sensor, such as an accelerometer, to provide a signal indicating torch tip contact with the metal workpiece to facilitate an initial height sensing routine or inadvertent torch contact with an obstruction as the torch moves horizontally during its programmed cutting process. In either instance, the vibration signal representative of torch contact is processed to stop the torch drive device and to raise the torch to the proper predetermined height.
