An automatic computer operated ramping method and system for extrusion coating wire by an extrusion coating system has an extruder that is driven by an extruder motor and a capstan that draws a wire through the extruder and that is driven by a capstan motor. The automatic ramping method and system determines the speed of the capstan motor while monitoring the extruder head pressure of the extruder with a pressure gage, accelerates the speed of the capstan motor and the speed of the extruder motor while continuously monitoring the extruder head pressure so long as the extruder head pressure is below a predetermined limit, and stops the acceleration of the speed of the capstan motor and the speed of the extruder motor when the extruder head pressure exceeds the predetermined pressure limit, and resumes the acceleration when the extruder head pressure is below the predetermined pressure limit until a desired production speed is reached.
