A method and system for encoding digital video picture data. The coating on the work piece is removed or ablated by a high energy heat source prior to being welded in a welding operation, such that high welding speeds are attained. The zero-crossing detector is coupled to the drive signal generator and coupled to receive a current sense signal representative of a switch current flowing through the switch. A gear mechanism allows molded features, e. The palm portion and the finger portion are releasably coupled together.
