ABSTRACT:
There is provided a method of controlling an electrode pressure application force in an electric gun provided with the electrode at the tip end of a movable arm which is driven by an electric motor comprising steps of setting a limit torque of the electric motor in advance, continuously measuring and storing an arriving position of the electrode at the tip end of the movable arm when the electric motor is driven, calculating an average value of groups of data of the stored arriving position, and continuously controlling to correct the arriving position to average value.
