  • Controlled output for welding
    Patent number: 6809293
    Abstract: A method and apparatus for welding is disclosed. It includes a source of power and a controller. An output feedback circuit provides feedback to the controller. The controller includes a comparator that compares the fedback signal to a threshold and/or detects a short on the output. A standby/welding control is responsive to the comparator. Also, an arc end control may be provided that terminates the arc in response to detecting an increase in arc length.
    Type: Grant
    Filed: March 25, 2003
    Date of Patent: October 26, 2004
    Assignee: Illinois Tool Works Inc.
    Inventors: Michael Sammons, Stephen Ferkel, Albert DeCoster, Mark Kadlec
