The arc length voltage characteristic of a DC arc is given by the equation V=24+4L where V' is the arc voltage in volts and 'L' is the length in mm. The static volt-ampere characteristic of the power source is approximated by a straight line with no load voltage of 80V and the short circuit current of 600A Then the optimum arc lenoth is (mm)
