<p>According to the present invention, in a welding machine that enables manual welding, a voltage reducing device is activated by detecting the turning-on of power to the welding machine, rather than by turning on an activation checking switch for the voltage reducing device, irrespective of AC or DC systems. By thus implementing a checking operation for the voltage reducing device automatically upon starting of the welding machine, the present invention provides an inexpensive welding machine such that checking of the voltage reducing device can be implemented reliably before the welding machine is used.</p> |
