A variable tip width adjustment system for use in continuous casting of a molten metal includes a feed tip nozzle downstream from a distribution box, the nozzle including a pair of feed tip nozzle members spaced apart to define a feed tip opening at a downstream edge of the feed tip nozzle members and a pair of end dams located on a drive side and an operator side of the roll casters, the end dams slidably engaged inside the tip nozzle, each dam being axially moveable in two directions inside the tip nozzle. The end dams are preferably actuated using a programmable controller and a stepper motor that is responsive to the signals of the programmable controller. The stepper motor is preferably connected to the end dam via flex connector and a connecting guide rod directed through a guide tube.
