WELDING APPARATUS WITH AUTOMATED WELDING WIRE RETRACTION

摘要

A method providing a welding apparatus (100) configured to supply a welding wire (136) to a welding gun (130) and a welding system implementing the same is described. The welding gun (130) has a trigger (134) and an opening where the welding wire (136) extends when the trigger (134) is activated. The method also has a computer with a user interface (126) that includes an automatic wire retract program, the program dynamically adjusting the amount of welding wire (136) 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 (130) and determines when the trigger (134) is disabled.
