The present invention relates to a multifunctional welding device capable of welding in various functional modes in accordance with a selected function with a single welding device. The multifunctional welding device enables CO_2 welding, metal active gas (MAG) welding, AC/DC tungsten inert gas (TIG) welding, plasma welding, and spool gun type metal inert gas (MIG) welding. In addition, the multifunctional welding device enables a single worker to weld with the single welding device, or enables two or three workers to separately weld at the same time. As a plurality of functions are included in the single welding device in two or three stages, the functions in the different stages are able to be used even though a power source or a fuse of one of the plurality of stages is malfunctioned. In addition, disadvantages such as an existing messy wire connection condition and the like is able to be solved as the wires are arranged in a single welding device. A first welding device comprises an A portion for AC/DC TIG welding and a B portion for CO_2/MIG/MAG welding. |
