Abstract
The present invention is directed to a control that upon detection of an autothread input determines the amount of time in which a motor of a drive assembly should be activated so as to precisely supply an initial segment of wire to a welding gun of a welding system. The control determines the requisite time necessary to precisely thread the welding wire based on a wire feed speed and gun length. The gun length and wire feed speed may be determined from a series of user inputs or read from memory. By limiting user involvement with the actual “feeding” of wire to the welding gun, a more precise segment of welding wire may be fed to the welding gun such that trimming of wire extending past the tip of the welding gun is not needed.
