Laser cutting machine can't light the cause and the solution 1: check whether the water is normal circulation, make the normal water cycle, if the water protection is broken, can use sub water protection;
2: some preset, the ammeter is swinging, if he does not swing, using a multimeter did laser power supply of 220 v into electricity, if it does, it is not the light, may be a power failure, need to change;
3: the power supply will also be on the GND P soil conservation justifying a fault and the ground water conservation section test if the bad, the + 5 v and AIN short to check the output power, if the light, is the potentiometer is broken, need to change;
4: if the program does not light, even the machine card can use a multimeter measuring 15 (
H）
Or 16 (
L）
Between horn and 14 had more than 3 v dc voltage, if any, that card is normal, no card is a problem with the signal;
5: a noise inside the laser power supply for the power connector poor contact, commonly to welding or connection, then blow the power supply inside the dust up;
