PROBLEM TO BE SOLVED: To determine whether correction of an electrode is proper or not with a high accuracy.SOLUTION: A correction accuracy determination device B for a welding electrode determines whether correction of a stationary side electrode 12 is proper or not in the state that a height of the stationary side electrode 12 (electrode) provided on a robot 10 which is so driven as to be elevated is corrected according elevation of the robot 10. The determination device includes: a conductive movable member 20 which is positioned above the stationary side electrode 12; a pair of upper and lower conductive detection members 21, 22 which are so located as to face a top face and an underside of the movable member 20; determines means 23 which, when the movable member 20 is pushed up to the stationary side electrode 12 of which a height is corrected and does not contact the detection members 21, 22, determines that the corrected height of the stationary side electrode 12 is proper.SELECTED DRAWING: Figure 9 |
