The present invention relates to a thyristor carbon dioxide (CO_2) welder. On the front control panel of a CO_2 welder main body, a plurality of switches, variable resistors, digital displays, and lamps are installed to make the control and display for performing the CO_2 welding become digital. By the same, the control and display for the CO_2 welding can be accurately performed, and since a power source for motor, cooling fan, and phase-synchronized signals can be provided by a single main transformer, an additional auxiliary transformer for providing phase-synchronized signals can be excluded, thus reducing production costs. |
