Abstract
The welding operation performed by the clamp 12 is under the control of a welding cabinet 15 including a servo-control unit 16' and an electronic switch 17. The clamp is moved from one weld spot to another by a robot 13 under the control of a control unit 14 provided with a servo-control unit 16. The switch 17 is controlled in such a manner that the welding operation and the beginning of the clamp opening operation and the end of the clamp closing operation are under the control of the welding cabinet 15 (with the robot then remaining stationary), while displacement of the clamp synchronizing with wide opening and closing thereof are under the control of the control unit 14.
