• Q

  What should operators notice during use?

  

  1)Operators must attend professional training and get permission of security administrator before operating;
  2)Operators must wear protective goggles and protective clothing. Good light in wearing protective goggles area ensures smooth operation. There must be processing rooms, protective fences and safety devices to avoid laser diffusion. When the door of processing room is open, please turn off laser device;
  3)Read carefully and follow strictly the operation instruction before use;
  4)Maintain equipments regularly, eliminate hidden troubles in advance;
  5)It is forbidden to dismantle components of external light path. If the equipment is unable to function properly because of your disassembly, HGLASER is not responsible.
  6)Non-professional personnel are forbidden to dismantle devices. Please do not damage the labels and covers, or broken products have no warranty;
  7)Any problems about products, please contact our after-sale maintenance personnel.

• Q

  How laser processing technology works?

  

  Laser processing technology utilizes the interaction of laser beam with objects to work with materials (including metals and nonmetals) for cutting, welding, surface treatment, drilling and micro processing. Laser technology is a comprehensive technology involved with optics, machines, electricity, materials and detection.

  Breakdown Maintenance of Laser Marking Machine

  

  1. Breakdown Phenomenon:
  Press the main switch, no response.

  Reason Analysis:
  1) No power or phase loss;
  2) The air switch is not closed;
  3) The emergency switch is pressed;
  4) Key switch is not open.

  Handling Method:
  1) Restore the power;
  2) Close the air switch;
  3) Back-out the emergency switch;
  4) Open the key switch.

   

  2.Breakdown Phenomenon:
  No laser or weak light

  Reason Analysis:
  1) In the state of over-temperature and lock light;
  2) The circulating cooling water is not clean;
  3) The xenon lamp aging;
  4) The laser pointer head face damage;
  5) Position offset of all and half reflection lens;
  6) All and half reflection lens are dirty;
  7) The laser pointer head face is dirty.

  Handling Method:
  1) Shut down till the equipment temperature back to normal;
  2) Replace the circulating cooling water;
  3) Replace the xenon lamp;
  4) Replace the laser pointer;
  5) Adjust the lens (Please contact with our technical staffs);
  6) Clean the lens (Please contact with our technical staffs);
  7) Clean the laser pointer head face (Please contact with our technical staffs).

   

  3. Breakdown Phenomenon:
  Fault hint of water temperature on LCD display screen

  Reason Analysis:
  1) The water temperature beyond warning temperature;
  2) The downpipe falls off;
  3) The control line fault;
  4) The water pump fault.

  Handling Method:
  1) Open laser power supply till the water temperature drops to normal;
  2) Reconnect the downpipe;
  3) Replace the circuit board (Please contact with our technical staffs);
  4) Repair or replace the water pump (Please contact with our technical staffs).    

  
  4. Breakdown Phenomenon:
  Power turn-off of equipment

  Reason Analysis:
  1) The power cable is loose or fall off;
  2) Overcurrent or overload protection.

  Handling Method:
  1) Check the wiring and connect again;
  2) Adjust the current to minimum and restart the device.
