WELDING POWER TO AUXILIARY POWER CONVERSION SYSTEM AND METHOD

摘要

Methods and systems for manufacturing and using the auxiliary power conversion unit, which is capable of being remotely located from a welding power supply unit during a welding operation, are provided. In some embodiments, the auxiliary power conversion is capable of outputting DC as well as AC power, capable of outputting multiple voltages consistent with the demands of typical auxiliary tools, such as a hand grinder or a light. In certain embodiments, the power conversion unit may be a stand-alone system or may be incorporated into a device, such as a wire feeder, which is configured to derive power from the arc potential. The power conversion unit may contain control and processing electronics that may include a controller, a processor, memory, and so forth.

主权项

1. An auxiliary power conversion device, comprising:
an input power converter configured to receive an input voltage from a welding power supply unit connected to the auxiliary power conversion device, and to convert the input voltage received from the welding power supply unit to a first output; an input-to-output isolation circuit configured to receive the first output and to maintain an auxiliary load at a different potential than the welding power supply unit, wherein the input-to-output isolation circuit is configured to transform the first output to a second output; and an output power converter configured to convert the second output to a desired waveform for the auxiliary load.
