ABSTRACT:
A d.c. arc welder which can use either a high voltage power supply of a certain voltage such as 400 volts or a low voltage power supply of about a half voltage thereof such as 200 volts and is arranged to effect automatic switching between low and high voltage power supply states not only when the power supply is switched from one to the other but also when the input voltage gradually rises from zero voltage to the above-mentioned high voltage, thereby constantly providing an adequate d.c. output for welding. It is provided with a circuit breaker in a stage next to its input terminals for sensing a high voltage of the power supply to temporarily shut off the input from the power supply and closing the circuit after its initialization.
