A cutting torch system comprises a cutting torch and a control system. The cutting torch includes a cutting oxygen channel for supplying cutting oxygen, a heating oxygen channel for supplying heating oxygen, a fuel gas channel for supplying fuel gas, an ignition mixer configured to selectively generate ignition gas from the heating oxygen and the fuel gas, and at least one sensor adapted for measuring a pressure and/or flow rate in one of the channels. The control system is adapted to maintain a temperature of the cutting torch to allow operation of the at least one sensor by adjusting a flow rate and/or a pressure of the gasses supplied to the cutting torch and/or by switching the cutting torch between an ignition mode and a cleaning and cooling mode.
