How to measure the voltage of the laser engraving machine and laser tube
If the laser tube to the energy decrease or no energy, we should first check the input voltage is laser tube, and then consider other possibilities.Laser engraving machine power plate normal output to the laser tube voltage is DC 48V, even if the external voltage is normal, if the power supply board has failed, may not be to the laser tube rated 48V, which will result in energy attenuation of the laser tubeor not working properly.Here is the method of detection of the laser tube voltage:
a) shut down, unplug the power plug of the laser tube.
b) boot file carving failure, transmission, and began carving (cutting) the normal working procedures.
c) To observe this plug consists of a number of fine wire and red, black and coarse wire, measure the voltage between any one red coarse wire and black coarse wire, to see if 48V Note multimeter be transferred to the DC voltage block.
d) If not 48V, the power board there is a problem. If it is 48V, then there may be other reasons the laser tube itself.
