    摘要: An arc welder which can be used with either a high voltage a.c. power supply of a certain voltage or a low voltage a.c. power supply of about a half of said voltage, such as 400 or 200 volts, for example, and which is provided with a circuit configuration in which an input a.c. voltage is rectified by a rectifier and smoothed by a pair of capacitors and the resultant d c. power is converted by an invertor into a high frequency a.c. power which is reduced in voltage by an output transformer and then rectified again, and arranged to discriminate the input a.c. voltage and switchingly connect these capacitors in series or parallel between both ends of the input rectifier, thereby automatically conforming the circuit to both high and low supply voltages.
