Abstract: The present invention is directed to a method and apparatus of controlling the output of a welding power source with a fused electrode detection circuit. The present invention incorporates a fused electrode detection circuit to regulate the output of the welding system power source. By providing feedback as to when the electrode begins to stick in the weld, the output of the power source may be regulated to allow easy diffusing of the electrode. That is, by reducing the output of the power source upon detection of a fused electrode condition, a user or technician can remove or unstick the electrode from the weld without having to shut down the power source or without forcefully removing it while power is on and creating large, damaging arcs. By limiting the output of the power source until the electrode is “unstuck”, the present invention reduces the likelihood of damaged electrodes, electrode holders, and welds.

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 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.
