Max Rated Power 8W 20W 50W 150W 300W
Application Precision welding of electronic components and medical components Electronic component field such as termination of coil Cu wire for motors, tab welding for batteries and welding of optical components It is useful in wide range of applications from electronic components and medical components to automobile components
Features
  • Deep weld penetration is improved by oscillation of higher brightness laser beam even at the same energy level
  • Uniform weld penetration is maintained and stable welding can be achieved in continuous output or simultaneous output as well
  • High and stable output
  • It is applicable to spot welding of highly reflective material, such as Cu, Al or Au, where high energy level is required and to seam welding where repetitive output is required

Branched Version

The laser beam output from the oscillator can be branched and output simultaneously through multiple light paths or output sequentially from multiple light paths.
Branched version can be selected at the time of order placement.

Single Branch

Single Branch

  • The laser beam is output from one light path
  • The laser beam of preset value is output

Time Branching (2 - 4 Branches)

Time Branching (2 - 4 Branches)

  • The laser beam is output in sequence from multiple light paths
  • The laser beam of preset value is output by switching the light paths

Simultaneous Branching (2 - 4 Branches)

Simultaneous Branching (2 - 4 Branches)

  • The laser beam is output simultaneously from the branched light path
  • The output energy per branch equals the value obtained by dividing the preset value by the number of branches

Simultaneous 2 and Times 2 Branches

Simultaneous 2 and Times 2 Branches

  • The laser beam is output in sequence for 2 light paths at a time
  • The output energy per branch equals half of the preset value

Output Head

  • This is a head to fabricate the work by focusing the laser beam output from the optical fiber
  • We have different models available including the small sized standard type suitable to be equipped on machines and a model with a CCD camera which enables welding while observing the welding position by a camera
  • Furthermore, focal length of the output head and lens diameter can be selected depending on the working distance or high repetition application

Caution

  • 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.
