In a cutting torch machine having an internal ignition device (10) on a cutting oxygen channel (8) which is in communication with an ignition gas generating mixing stage (14), the mixing stage can be connected via a controlling heating oxygen pressure reducer (6) and at least one heating oxygen solenoid valve (5) to a heating oxygen source and via a fuel gas solenoid valve (15) to a fuel gas duct. The cutting torch machine includes, on a valve body (4), connecting nipples for fuel gas, for heating oxygen and for cutting oxygen. Preferably, a heating gas injector (12) is provided within valve body (4). In order to increase operation safety, mixing stage (injector 14), heating oxygen pressure reducer (17) and solenoid valves (5, 15) are disposed within the valve body, and mixing stage (14) is connected via fuel gas solenoid valve (15) to connecting nipple (3) for fuel gas and via heating oxygen pressure reducer (17) and heating oxygen solenoid valve (5) to connecting nipple (2) for heating oxygen.
