Abstract
In an embodiment, an electrode holder assembly (100) includes a current delivery base (105) having an interface (204) sufficiently designed to distribute an electrical current; a buss plate (200) sufficiently designed to provide the electrical current to the current delivery base (105); a shoe-ring assembly having: a plurality of electrical shoes (120), wherein the electrical current from the current delivery base (105) is distributed to the plurality of electrical shoes (120) for distribution to an electrode (400); a plurality of dual stroke cylinders (190); and a mounting ring (220); and a hydraulic assembly (300) including a grip ring (310) having an opening sufficiently designed to engage an outer surface of the electrode (400); a pressurizing cylinder (320) sufficiently designed to constrict and relax the grip ring (310); and at least one dual stroke cylinder (330) sufficiently designed to control horizontal movement of the grip ring (310) and the electrode (400).
