ABSTRACT:
An electrode position detection system for a welder having a laser that is projected in a lateral plane to laterally cross a welding wire at a location below a contact tip of a welding gun and a receiver that receive the laser bean after crossing the welding wire, and a measuring device that determines one or more parameter of the welding wire based on the received laser beam. Arc voltage measurements can also be used to determine one or more parameter of the welding wire.
