| titleOfInvention | Arc welding machine and plasma cutting machine |
| abstract | (57) [Abstract] [Object] In an arc welding machine and a plasma cutting machine, It is possible to protect the unidirectional rectifying element, eliminate the danger to the human body due to the distribution capacity of the extension cable, and obtain a stable arc start success rate. SOLUTION: An output of a first DC power supply 1 having a drooping characteristic or a quasi-constant voltage characteristic is supplied to a welding load or a cutting load via a unidirectional rectifying element 3, and a DC high voltage is applied to the welding load or the cutting load. The second DC power supply 2 of the drooping characteristic type for voltage application is connected, and when the arc is started, a high DC voltage is applied from the second DC power supply 2 to the welding load or the cutting load, In an arc welding machine or a plasma cutting machine configured to stop after an arc is generated, a voltage clamp element 8 is connected in parallel to the unidirectional rectifying element 3, and a DC high voltage generator 9 is arranged in the vicinity of a welding load or a cutting load. The circuit configuration is such that the maximum value of the reverse leakage current of the unidirectional rectifying element 3 is 1 mA or less. |
