ABSTRACT:
A voltage converter is disclosed which converts an open circuit voltage from approximately 80 volts to about 120 volts DC. The voltage source which is converted is supplied by a welding machine. The converted voltage is used to power electric tools while drawing a relatively small amount of power from the welding machine. The converter includes a housing with two input leads for connection to the welding machine and an output receptacle in which electrical tools are plugged to receive power. Inside the housing are the components of the voltage conversion circuitry which latter is adapted to convert to an output voltage at the desired level. In an alternative arrangement, the circuit may produce an AC output voltage instead.
