Laser cutting machine of the xenon lamp can't normal precombustion processing ( 1) Measuring whether there is voltage on both ends of the lamp, lamp and check the connection is correct, two lights line of two positive pole and negative pole must not cross connection. ( 2) If no voltage measurements at both ends of the lamp, diagnosis according to the following steps: a. Check on ignition board is loose, the plugin on the cable is disconnected. b。 Check whether the insurance on the 840 v transformer tube is open. c。 Check whether the rectifier diode is short circuit or open circuit. d。 Check whether the current limiting resistor is open, 1. 8k/50W×4) 。 ( 3) If there is voltage measurements at both ends of the, diagnosis according to the following steps: a. Check the ignition pressure resistance is open. b。 Check the ignition filter capacitor are in good condition. c。 Check whether 8 uf / 630 v capacitance in good condition. d。 Check whether there is J5 relay action. e. Check whether isolation diodes short circuit or soft breakdown. ( 4) Check whether the xenon lamp is in good condition, swap xenon lamp precombustion comparison
