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 length is (mm).
In relation to the circuit presented below, mark the alternative(s) that you consider correct. 1 To enable actuator A2 to advance, it is necessary to switch valve V2 to the leftmost position and ensure that valve V1 is in its initial (intermediate) position. 2 Switching valve V2 to the leftmost position allows actuator A2 to advance, but for this to happen, valve V1 must also be switched to the leftmost position. 3 When activating valve V1, using the locking lever installed on the left side of it, the two actuators (A1 and A2) are allowed to advance. 4 Hydraulic pump B1 is a simple variable displacement type. 5 Valves V1 and V2 have a TANDEM center.
