ABSTRACT:
This invention is in connection with a sliding shunt type of welder wherein the improvement consists of a shunt being released positioned and secured relative to the core of the welder by a single hand action of the operator, the shunts being carried by a pair of channel members connected by a frame member, the channel members being slideable in a track moveable into and out of operative relationship with said core and with one of the channel members having movement relative to the other channel member and being spring pressed into a normal locked position and with this channel member being released by the squeezing of a handle carried by the frame which retracts the spring bearing against the one channel member and frees both channel members for movement in the track relative to the core by a simple squeezing hand action of the operator.
