• ML-6700B


The fiber laser welders developed first in Japan!

For cleaner and finer welding!
Model : ML-6700B

  •  Stable clean weld without heat affected area.
  • ◆ High efficiency fiber laser system contributes reduction of CO2 emission. (Its power consumption is approximately 75% less than the lamp-pumped laser welders.)
  • ◆ Real-time Power Feedback feature ensures stable welding under optimum weld conditions.
  • ◆ Up to three energy sharing and time sharing. (Option)
  • ◆ Small footprint design saves spacing.
  • ◆ Up to 2 deliveries of laser output are available at powersharing; up to 3 deliveries of laser output at timesharing. (Option)


 Real-time power feedback

The laser output in the lamp-pumped module is monitored in real time. The monitored laser output is compared with the set waveform and power is fed back in real time, varying the energy input to the lamp to reproduce the set waveform and obtain the ideal laser output waveform.


 Waveform control

Equipped with a "fixed mode" that features three-level waveforms, and a "flex mode" to provide more complex waveforms.


 Power monitor

Laser energy (J) and average power (W) are monitored to detect abnormalities.


 Color LCD touch panel

The touch panel can be detached from the main unit and operated by hand.


 External communications

Configuration of parameters and monitoring of performance can be carried out from a separate location.

- Type: RS-485 compliant, asynchronous, full duplex

- Data speed: 9600, 19200, 38400 bps



This feature avoids marks at the end of seam welding and provides a beautiful finish even for overlapping circumference seam welding sections.
