ABSTRACT:
In a cutting torch machine having an internal ignition device on a cutting oxygen channel which is in communication with an ignition gas generating mixing stage, the mixing stage can be connected via a controlling heating oxygen pressure reducer and at least one heating oxygen solenoid valve to a heating oxygen source and via a fuel gas solenoid valve to a fuel gas duct. The cutting torch machine includes, on a valve body, connecting nipples for fuel gas, for heating oxygen and for cutting oxygen. Preferably, a heating gas injector is provided within the valve body. In order to increase operation safety, the mixing stage (injector), heating oxygen pressure reducer and solenoid valves are disposed within the valve body, and the mixing stage is connected via the fuel gas solenoid valve to the connecting nipple for fuel gas and via the heating oxygen pressure reducer and the heating oxygen solenoid valve to the connecting nipple for heating oxygen.
