<p>The present invention relates to a hybrid multifunctional welding device. According to the present invention, the hybrid multifunctional welding device comprises a power source unit which converts AC voltage into DC voltage by using ordinary commercial electricity and includes an input power source, a power input terminal, an inverter unit, and a power supply unit to supply the converted DC voltage; a transformer which drops the DC voltage input from the power source unit; an output unit which includes a positive pole output terminal connected to a rectifier and a reactor to output current so that CO2 welding, manual metal arc (MMA) welding, tungsten inert-gas (TIG) welding, metal inert gas (MAG) welding, and meal active gas (MAG) welding are performed by receiving the dropped DC voltage from the transformer and a negative pole output terminal comprising a CO2 output terminal and a TIG output terminal which are connected to a high frequency generating device for controlling the high frequency of power; a switching unit which supplies a power of 220 V, 280 V or 440 V as needed by switching the power to be input to the power source unit; and a control unit which enables a user to select a welding mode by using a resistance welding control panel and an arc welding control panel according to the on-off operation method of the switching unit to perform a welding work, wherein the resistance welding control panel is converted into a TIG welding mode and an arc welding mode while the arc welding control panel is converted into a CO2 welding mode, an MIG welding mode, and an MAG welding mode.</p> |
