(1)   From N-1 step location, the fixed tip moves to a location at a distance of fixed tip clearance from the record location.

 

(2)   The fixed tip moves to the record location of the step through the robot equalizing operation, and the moving tip squeezes the panel using air pressure.

 

(3)   When the squeeze alignment is achieved, the welding execution signal will be output together with the welding condition signal at that location.

 

(4)   When the welding complete signal (WI) is received, the fixed tip moves to a location from the record location that is equal to the fixed tip clearance, and the moving tip moves to a location where air pressure is not supplied.

 

(5)   Continue to the next step.
