HYBRID WELDING SYSTEMS AND DEVICES COMPRISING A FUEL CELL AND AN ENERGY STORAGE DEVICE

摘要

A hybrid welding device including a fuel cell (40) and an energy storage device (42) 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 (36) coupled to a generator (38) 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.
