Abstract

PURPOSE:To prevent an electric current control element from breaking down by connecting a voltage detection part to a welding output end or both ends of the current control element and displaying that the abnormal input voltage enters arc welding equipment. CONSTITUTION:The voltage detection part 12 is connected between a collector and an emitter of a transistor 11 as the current control element of the arc welding equipment and when the abnormal input enters the arc welding equipment, the detection part 12 detects this which is displayed on a display part 13. Or a voltage detection part 14 is connected to the output end of the arc welding equipment 15 and when it detects the abnormal input, this is displayed. Further, the voltage detection part 14 can be connected to any place where super-electric power generated by inductance of an output cable 2 can be applied.
