  • Manual welding apparatus having an automatic wire retract method
    Patent number: 11198191
    Abstract: A method providing a manual welding apparatus configured to supply a welding wire to a welding gun. The welding gun has a trigger and an opening where the welding wire extends when the trigger is activated. The method also has a computer with a user interface that includes an automatic wire retract program. The program monitors the welding gun and determines when the trigger is disabled. The program indicates when a first condition is satisfied and retracts the welding wire so the welding wire does not extend from the opening of the welding gun.
    Type: Grant

  • Welding apparatus with automated welding retraction
    Patent number: 10562124
    Abstract: A method providing a welding apparatus configured to supply a welding wire to a welding gun and a welding system implementing the same is described. The welding gun has a trigger and an opening where the welding wire extends when the trigger is activated. The method also has a computer with a user interface that includes an automatic wire retract program, the program dynamically adjusting the amount of welding wire retraction based at least upon one of the following: welding are current, welding wire size, welding wire speed and burnback time. The program monitors the welding gun and determines when the trigger is disabled. The program indicates when a first condition is satisfied and retracts the welding wire so the welding wire preferably does not extend (or minimally extends—or may be at least partially recessed within the tip) from the opening of the welding gun nozzle tip. The system and method also includes an ability to stop advancement or retraction of the wire to prevent damage.

  • Welding apparatus with automated welding wire retraction
    Patent number: 9498839
    Abstract: A method providing a welding apparatus configured to supply a welding wire to a welding gun and a welding system implementing the same is described. The welding gun has a trigger and an opening where the welding wire extends when the trigger is activated. The method also has a computer with a user interface that includes an automatic wire retract program, the program dynamically adjusting the amount of welding wire retraction based at least upon one of the following: welding arc current, welding wire size, welding wire speed and burnback time. The program monitors the welding gun and determines when the trigger is disabled. The program indicates when a first condition is satisfied and retracts the welding wire so the welding wire preferably does not extend (or minimally extends—or may be at least partially recessed within the tip) from the opening of the welding gun nozzle tip.
