Welding wire positioning system and method

摘要

An electrode position detection system for a welder having a laser (70) that is projected in a lateral plane to laterally cross a welding wire (32) at a location below a contact tip (22) of a welding gun and a receiver (90) 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. <IMAGE>
