制御手段を設けたことを特徴とするスポツト溶接
機の溶接電流調整装置。 In a welding current adjustment device for a spot welder that compensates for a decrease in welding current density due to wear and tear of an electrode tip that pressurizes a workpiece, a nugget is installed near the electrode tip just after welding the workpiece. An indirect thermometer is installed to measure temperature without contact.
A welding current adjusting device for a spot welding machine, characterized in that a welding current control means for controlling the welding current based on the electric signal from the indirect thermometer is provided on the primary side of the welding transformer.
