Oscillator Structure

Normal Incidence to the Work is Possible

As the generator has a structure that is resistant to reflected light from the work, it prevents operation stop or failure caused by the reflected light.

  • Our laser welder products comply with the "Safety of laser products" of Japanese Industrial Standards and the "Preventive measures against interference by laser beam", a notice from the Ministry of Health, Labour and Welfare.
  • When using a laser welder, please make sure to follow the instruction manual and label or caution note displayed on or attached to the product.

Laser Beam

  • Our laser welder products correspond to class 4 laser. Make sure not to have the beam emitted from the laser welder get directly into your eyes.
    Even the reflected light or the scattered light is very dangerous. Be careful not to have the light get into your eyes.
  • In case the laser beam is irradiated on human body, there is a possibility for a serious interference to be caused. Be sure to wear a laser protection gear within an area where the laser beam may reach you.
  • Do not irradiate laser beam into the air. Be sure to terminate.
  • Do not irradiate laser toward an inflammable object. A fire may be caused.

High Voltage

  • When replacing a flash bulb or removing the power supply cover, turn the power OFF and wait for 5 minutes before doing so.
  • Be sure to ground the ground terminal of the chassis.

Handling of Laser Welder

  • Appoint a laser safety administrator.
  • Establish a laser controlled zone for safety control.
  • Never modify the equipment.
