Welding apparatus with automated welding wire retraction

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