Welding machines with VRD

— this function is used to significantly reduce the open circuit voltage of the machine.When the VRD is turned on, the open electrodes receive not a standard voltage of several tens or even hundreds of volts, but only 9-12 V. At the same time, the operating parameters are restored automatically — when the electrode touches the workpiece and a high current occurs; and when the arc is extinguished, the voltage again drops to the minimum values. This format of work provides two main advantages. Firstly, it provides additional security: in particular, closing contacts with a hand or other part of the body does not lead to a serious electric shock, and the risk of such an injury in high humidity is also reduced. Secondly, lower voltage helps to save energy.
