ークスポツト溶接装置用の中継装置。 A relay device for an arc spot welding device connected between a welding power source device that controls a welding current to be supplied to a welding electrode and a welding machine control device that controls starting and stopping of the welding power source device using a welding start signal. a no-load voltage detection means connected to a power output terminal of the welding power supply device to detect the power output voltage and output a no-load voltage signal when the detected value is larger than a predetermined reference value; emergency stop signal output means for outputting an emergency stop signal when an automatic operation signal indicating that the device is in an automatic operation state is not output from the welding machine control device;
A cutoff that is connected to the emergency stop signal output means and the no-load voltage detection means and outputs a power cut-off signal from the time when the no-load voltage signal and the emergency stop signal are both output until the output of the emergency stop signal is stopped. An arc comprising: a signal output means; and a start signal cutoff means for receiving a power cutoff signal from the cutoff signal output means and cutting off the welding start signal from the welding machine control device to the welding power supply device. Relay device for spot welding equipment.
