An electrode lifting apparatus provides a mechanism for lifting a free electrode in a vertical orientation and moving the free electrode suspended below the lifting apparatus to a location for a joining procedure with another electrode or portion of an electrode. The electrode lifting apparatus also supports the free electrode during a joining procedure that includes driven rotation of the free electrode by an electrode torque station. The electrode lifting apparatus includes a bail and a body, the body having a yoke and a housing. First and second arms on the body connect the housing to the yoke. The body may angularly rotate relative to the relatively fixed bail about a reference vertical axis during driven rotation of the free electrode by the torque station. A threaded stem attached to the bail provides a threaded engagement with the yoke allowing such relative angular rotation in some embodiments.
