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.
