<p>Cylinder body has pressure fluid connections for a pair of pistons which move reversibly, and are connected by a piston rod and limited in movement by a bottom stop. An electrode-carrier casing is conical and is connected to the front end of the piston rod by an elastic element which absorbs the vibratory forces produced by the electrode contacting the weld piece, and suppresses them.</p> |
