Abstract
PURPOSE:To quickly discharge the active gas and shorten the waiting time by providing an exhaust valve on switching valves installed upstream an active gas feed path. CONSTITUTION:Solenoid valves 6 and 8 and pressure regulators 9 and 10 are provided on feed pipes of an active gas feed path 5 and an argon gas feed path 4, and an exhaust valve 7 is provided on an air feed pipe. After the processing such as metal cutting by active gas plasma is completed, the voltage application across a cathode 1 and a work 12 is stopped, switching valves 6 and 8 are closed, then the high-pressure active gas in a torch and pipes is discharged through the opening of a nozzle 3 and also discharged through the exhaust valve 7 with the flow path area sufficiently larger than the flow path area of the opening of the nozzle 3. The pressure in the active gas feed path 5 can be quickly decreased to the atmospheric pressure, and the waiting time can be shortened.
