A current-conducting arm for conducting a current from at least one cable supports to an electrode in an electric arc furnace comprising an arm housing having a U-shaped base channel member and a U-shaped top channel member. Both channel members have a first and second wall, with the top channel member being inverted such that the first wall of the top channel member can be joined with the first wall of the base channel member, and the second wall of the top channel member can be joined with the second wall of the base channel member. The arm housing therefore has four annular corners to improve the conduction of current through the arm housing to the electrode. The invention further includes a spring assembly used to provide to aid an electrode holder in clamping the electrode. Moreover, a laser pointer is included for guiding the positioning of the arm housing in the electric arc furnace.
