ABSTRACT:
An apparatus for mounting a cutting torch to a shape cutting machine is disclosed, and which incorporates a control system for signaling the machine in the event the torch contacts an obstruction during either vertical or lateral movement of the torch by the machine. The control system includes a pair of plates mounted to the torch so that the plates are displaced relative to each other when the torch contacts an obstruction, and a number of gas release valves are mounted to the plates and which are connected to a gas line so that a signal is generated upon a relative displacement of the plates. The signal is directed to the control logic of the shape cutting machine so that it may take corrective action.
