Abstract
A hybrid welding device including a fuel cell and an energy storage device that cooperate to power a welding operation and/or an auxiliary operation are provided. In some embodiments, the hybrid welding device may also include an engine coupled to a generator that is configured to supplement the power provided by the fuel cell and/or the energy storage device. The hybrid welding device may be adapted to provide power for a welding operation and/or an auxiliary operation when operated as a standalone unit and/or when connected to a primary source of utility power.
