Claim Text:
1. An automatic wire retract method comprising: providing a manual welding apparatus having at least a welding power source, a wire feeder configured to supply a welding wire, and a welding gun having a trigger and an opening from which the welding wire extends; providing an automatic wire retract program having a retract delay time; configuring the manual welding apparatus to include the automatic wire retract program; monitoring when the trigger is enabled to extend the welding wire from the wire feeder to the opening, and extending the welding wire out of the opening of the welding gun; determining a first amount of time when the trigger is disabled; determining when the first amount of time is at least equal to the retract delay time, wherein the trigger is disabled during the first amount of time; and at least partially retracting the welding wire into the opening of the welding gun for a retract distance or a retract time, said step of at least partially retracting dynamically based upon at least one of the following parameters: welding arc current, welding wire size, welding wire feed rate and burnback time.
