The present invention relates to a hybrid welding device capable of integrating welding devices having various driving methods, and selectively utilizing the welding device. The present invention comprises: an input rectification module rectifying an inputted alternating current into a direct current; a smoothing module smoothing the direct current rectified by the input rectification module; first and second inverters electrically connected to the smoothing module, and converting the direct current of the smoothing module into an alternating current; a route controlling switch controlling the smoothing module to electrically be connected between a first inverter and a second inverter; a first trans converting an alternating current of the first inverter; a second trans converting an alternating current of the second inverter; a first output rectification module rectifying an output current of the first trans into a direct current to be outputted through a first welding torch and a first grounding line; and a second output rectification module rectifying an output current of the second trans to be outputted through a second welding torch and a second grounding line. |
