ABSTRACT:
Three parameters represent speed, current and voltage are combined to produce an electrical signal representing a desired uniform heat for an operation in which a movable workpiece is involved. A set of electrical signals are developed during the actual operation and combined with the electrical signal representing the standard heat. A resulting error signal and feedback circuit maintain the heat at the workpiece substantially at the desired uniform heat.
