Abstract
A metering system and associated method for supplying gas to a torch are provided. The metering system includes a controller that is configured to adjust a pressure regulator according to the pressure and flow rate of the gas delivered to the torch. For example, the torch can be a plasma arc torch that has an electrode positioned in a nozzle and operates in a working mode by providing an arc from the electrode to a workpiece. In a first mode of operation, the metering system can provide a gas to the torch by adjusting the pressure regulator according to the pressure downstream of the pressure regulator. In a second mode of operation, the metering system can provide adjust the pressure regulator according to the flow rate of the gas through a flow transducer in series with the pressure regulator. Further, the metering system can be configured to monitor the downstream pressure and the flow rate of the gas and determine therefrom whether there exists in the torch a double arc or other operating condition that affects the flow of the gas through the nozzle.
