Developed was a new remote control device of control-cableless type for AC are welding machine. Important features of the new device were that a reference voltage of servomechanism for locating the movable iron core of welding machine at a desired position was selected among a number of ones prescribed on potentiometers before start of welding works and so welding current was regulated in a stepwise manner according to a control signal which was generated at the control box on the welding site and fed to welding machine through welding cable. Therefore, it is unnecessary to use a troublesome control cable to transmit a reference voltage to welding machine. Compensation of the settings of welding current for variation in input voltage and performance of the newly developed device operated simultaneously with usual voltage reducing device were discussed. Satisfactory operation of the device was recognized with error of less than ±2% in spite of fairly strong noise from universal motor of control use. Using this device, even a less experienced welder could regulate welding current correctly and rapidly with the simple operation of control box. It is hoped that successful application of the new device will serve to enhance labor-saving, efficiency of welding works and assurance of weld quality.
