An apparatus for forming electrode heads includes a first and second lost-wax areas; a first and second electrode head forming areas; and a first, second and third transfer units. The first transfer unit rotates an electrode plate group from a horizontal to a vertical orientation. The second transfer unit holds the electrode plate group oriented vertically, and delivers it to be dipped in wax in the first lost-wax area, and then delivers the wax dipped electrode plate group to the first electrode head forming area to form one electrode head on one end thereof. The third transfer unit rotates the electrode plate group with the first electrode head, and delivers it to be dipped in wax in the second lost-wax area, and then delivers the wax dipped electrode plate group with the first electrode head to the second electrode head forming area to form another electrode head on thereof.
