Abstract

PURPOSE:To enable to stable processing quality to be maintained by informing the abnormality of a plasma torch on the basis of the flow change of working gas supplied to the plasma torch and voltage change applied to the electrode of the plasma torch. CONSTITUTION:Voltage applied to a plasma torch 1 and gas flow rate supplied to the plasma torch 1 are monitored at all times by a voltage detection means 5 and a gas flow detection means 10. And if at least one of the output of the voltage detection means 5 and the output of gas flow detection means 10 misses the specified ranges set respectively in advance, it informs the abnormality by an informing means 14 as the exhaustion of an electrode 2, exhaustion of a nozzle 3 or clog of the nozzle 3. Accordingly, a worker is released from visual monitoring of abnormality and can detects the performance deterioration of a plasma jet in advance. Hereby, stable processing quality (cutting quality, welding quality, etc.) can be maintained.
