  • Arc length measurement and control by optical scanning
    Patent number: 4093844
    Abstract: An arc length welding control system in which a welding arc is established between a pair of electrodes. An optical device optically senses the arc and produces signals related to the arc. An optical circuit is responsive to these arc signals for measuring the arc length and produces data signals related to that length. One or more control devices are varied in response to the data signals for controlling the length of the arc to a desired value.
