A water-cooled arc furnace electrode includes a hollow metallic jacket having a cylindrical wall portion supported in spaced relation from a graphite electrode. A shell is spaced from and surrounds the wall portion and has a section extending below the wall portion and upwardly into engagement with the lower end thereof. A baffle is disposed between the wall portion and the shell to define a first cooling fluide passage for water flowed downwardly between the shell and the baffle and a second passage extending upwardly between the baffle and the wall portion. A plurality of spaced electrical contact members are mounted on the lower portion of the shell and are in pressure engagement with the electrode. The shell and the contacts provide a current path around a proportion of the electrode for increased conductivity and to minimize electrode oxidation.
