Abstract

Systems and methods for facilitating the starting and stopping of arc welding processes, as well as for responding to events in mid-weld. Specially designed signals may be briefly applied between a welding electrode and a welding workpiece at the start and end of a welding process to gracefully and properly start and stop a weld. Furthermore, specially designed signals may be briefly applied in the middle of a welding process, if determined events occur, to counter the undesirable effects of the events.
