Abstract

In a spot welding gun which is made up of a gun main body which is operated for equalization by a driving source, a stationary electrode tip which is immovable relative to the gun main body, and a movable electrode tip which is connected to a pressing source, both electrode tips are pressed to a workpiece with an even force, to thereby perform a high quality spot welding. The driving source is controlled such that the electrode force of the stationary electrode tip, by the driving source, to the workpiece becomes substantially zero. In this manner, there occurs no difference in the electrode forces by both the electrode tips to the workpiece.
