Abstract

PURPOSE: To prevent burning accident of transformers due to an increase of exiting current which occurs when voltage cutover tap is connected to the low voltage side, by connecting automatically the input to a voltage switching tap of the transformer which coincides with the supply voltage through input voltage discriminating circuit installed in the arc welding machine.
CONSTITUTION: In the control device of said arc welding machine, the voltage applied across input terminals 1 and 2 from the power source to which the arc welding machine is connected, is discriminated by input voltage discriminating circuit 10. Then the input is connected to voltage switching tap 3 or 4 of transformer 6 which coincides with the voltage of power source to which the are welding machine is connected, by changing contact point 11 or 12 of electromagnetic contactor. As a result, it is not required to change the voltage switching tap of transformer in the arc weld- ing machine manually whenever the voltage of power source to which the arc welding machine is connected, changes.
