Abstract
An adjustable length linear bus bar for conducting a current between an induction heating power supply and an induction heating coil. The bus bar includes a fixed bar having a channel formed along the length of the fixed bar and a movable bar having a portion formed to slidably fit inside the channel of the fixed bar. A hydraulic ram biases the slidable bar against the fixed bar to facilitate the transfer of current between the fixed and movable bars. A clam shell type of construction allows the inductor coil to be quickly moved into and out of a gap between a pair of articles being heated.
