WELDING APPARATUS WITH AUTOMATED WELDING WIRE RETRACTION

摘要

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, 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 either does not extend (or minimally extends) from the opening of the welding gun.
