Publication number: 20230015497Abstract: Systems and methods are provided for manually setting up a wire drive assembly of a welding power supply and automatically setting up welding power supply parameters. A drive roll is configured with multiple grooves for receiving multiple wires of different types and/or different diameters. A sensor can detect the configuration of the drive roll such as, for example, being configured to receive a particular wire type with a particular diameter in a particular groove, by detect a distance to the drive roll. The welding power supply can use this information to automatically set the wire speed.Type: ApplicationFiled: April 25, 2022Publication date: January 19, 2023Inventors: Adam Richard Schmitz, Chris J.
