Title:
インバータ溶接機
Document Type and Number:
Japanese Patent JP7426561
Kind Code:
B2
Abstract:
An input detector detects the frequency of an input alternating current voltage, and generates a first output signal indicating the detected frequency. An output detector detects an output value, and generates a second output signal indicating the detected output value. A selecting unit selects one of a first waveform mode which generates a welding current having an inverter waveform, and a second waveform mode which generates a welding current having a thyristor waveform, and generates a third output signal indicating which of the first waveform mode and the second waveform mode has been selected. A control unit controls an inverter in accordance with the waveform mode selected by the selecting unit, on the basis of the first output signal from the input detector, the second output signal from the output detector, and the third output signal from the selecting unit.
