In order to ensure the accuracy of the detection parameters, the direct current arc welding electromechanical parameter detection equipment needs to be periodically calibrated. The comparison method is generally adopted for calibration, and a power supply device capable of covering the parameters of the universal direct current arc welder with input and output current, voltage and power is needed during the comparison method for calibration.
At present, when calibrating an electromechanical parameter detection device for direct-current arc welding, a direct-current arc welder with a large rated welding current is generally adopted as a power supply for calibration. However, the rated current of the direct current hand arc welding power supply except the direct current submerged arc welding power supply is generally within 630A, and neither the input nor output parameters thereof meet the requirement of a calibration range; if two or three direct-current manual arc welding power supplies are used in parallel, the two or three direct-current manual arc welding power supplies are temporarily connected in parallel, and two or three direct-current manual arc welding power supplies are simultaneously regulated, so that the calibration is very time-consuming; because the direct current submerged arc power supply belongs to a special welding power supply, the direct current submerged arc power supply has the advantages of multiple functions, complex control system and high cost, and if the direct current submerged arc power supply is used as a power supply for calibration, the calibration cost is also high.
