A method and system for optimizing a weld schedule is disclosed. The weld schedule is used to control a plurality of welding apparatuses, and includes a plurality of weld sequences for control the plurality of welding apparatuses. The weld sequences each define one or more weld events. Each of the weld events defines a weld operation and a duration of the weld operation. The weld schedule is analyzed to determine if any time points in the weld schedule have two or more weld events scheduled where the aggregate current demand exceeds a maximum current threshold. If such a conflict in the weld schedule is identified, the weld schedule is modified by rescheduling a lower priority weld event. The method executes iteratively until all conflicts in the welding schedule are resolved.
