ABSTRACT:
The present invention is directed to a power supply that maintains power supply to a plurality of electronic components of a welding system when an arc voltage falls below approximately 15 volts. The invention includes a power supply having a secondary supply circuit that improves the operable range of the power supply by maintaining power to components of a welding system when the arc voltage at a weld is greater than or equal to approximately 10 volts. As a result, the operable range of the power supply is no longer limited by the arc voltage. The invention includes a secondary power supply circuit having a power switch that when activated causes a buildup of energy in the transformer assembly whereupon deactivation of the power switch in the magnetic core is exhausted such that power supply is maintained. The power switch regulates the transformer assembly such that sufficient secondary power is provided if the input voltage to the transformer is as low as approximately 10 volts.
