Patent number: 10065261Abstract: A welding machine power supply apparatus outputs welding current in accordance with welding conditions set through operation of a display and setting unit (20). When a welding operation is ended while the welding machine power supply apparatus is operating, the welding conditions effective at the time the welding operation is ended are automatically stored in a memory (16). When any ones or more of the welding conditions at the time when the welding operation is resumed by the use of the welding machine power supply apparatus are different from the one or ones which were effective when the welding operation was ended, a load button (70), a rotary encoder (64) and a set button (72) are operated to cause a control unit (14) to read out the welding conditions stored in the memory (16) which were effective when the welding operation was ended, and to set the read-out welding conditions in the welding machine power supply apparatus.Type: GrantFiled: February 25, 2015Date of Patent: September 4, 2018Assignee: SANSHA ELECTRIC MANUFACTURING CO., LTD.Inventors: Takeshi Morimoto, Hiroshi Sasou

Publication number: 20180097336Abstract: A power supply apparatus includes a power supply for supplying power to a laser oscillator. A reactor has one end serially connected to the laser oscillator and another end serially connected to the power supply, and a parallel diode configures a closed circuit for serial connection of the laser oscillator and the reactor. A current detector detects a current flowing in the reactor, and a first switching device is connected in parallel to the laser oscillator and drives the laser oscillator with pulses. An energy consumption circuit prefetches a current command value based on a control signal from a controller upon driving the laser oscillator with pulses, and when the current command value is smaller than a current command value of a previous pulse, the energy consumption circuit consumes energy until the current command value reaches a predetermined target current value.Type: ApplicationFiled: February 18, 2016Publication date: April 5, 2018Applicant: Mitsubishi Electric CorporationInventors: Shingo TSUDA, Taichiro TAMIDA, Takashi HASHIMOTO, Takeshi Morimoto
