Abstract
Change in outputs from a pair of distance sensors mounted on a pair of gun arms is monitored to determine whether or not the gun arms have started to move toward opening to activate the robot carrying the welding gun. If no change in output occurs in either sensor when an instruction is given to open (generally because a fusion weld of the electrode to the workpiece has occurred), an alarm is activated and the robot is not.
