Pressure is then brought to bearupon the upper clamp, which is movableand insulated from the lower clamp, sotbat the ends of the rails bear firmlyagainst eaoh other, and the current fromthe transformer is then gradually admittedto the welding clamps through the coppercables D D. As the electrical resistanceof the secondary circuit is greatest at thepoint of contact between the two rails, an 07.
