<p>PURPOSE: A power supply control device of a digital pulse welder is provided to automatically adjust the maximum current output time of a pulse waveform, thereby stably providing a pulse. CONSTITUTION: A low frequency rectifier(1) rectifies an AC voltage to a DC voltage. A smoothing condenser(2) smoothes the output voltage of the low frequency rectifier. A power converter(3) converts the DC voltage outputted through the smoothing condenser into a pulse waveform. A high frequency transformer(4) transforms the DC voltage into a high frequency voltage. A high frequency rectifier converts the high frequency voltage into a DC voltage.</p> |
