• ML-6810B


The first kW-level fiber laser welder in Japan!

For high speed seam welding and even cutting!
Model : ML-6810B

·           AMADA MIYACHI's own developed high power fiber laser oscillator is employed.

·        ◆Stable clean weld without heat affected area.

·        ◆Ideal quality beam enables welding of thin films and even fine plates at high speed.

·        ◆High efficiency fiber laser system contributes reduction of CO2 emission. (Its power consumption is approximately 75% less than the lamp-pumped laser welders.)

·        ◆Employing long-life laser diode reduces maintenance cost.

·        ◆Real-time Power Feedback feature ensures stable welding under optimum weld conditions.

·        ◆Built-in power monitor supports better quality control.

·        ◆Up to 2 deliveries of laser output are available at powersharing; up to 3 deliveries of laser output at timesharing. (Option)

·        ◆Unique design which avoids influence of beam reflection on a workpiece enables straight incidence from the vertical position.

·        ◆CE and CDRH standards certified.

·        ◆Small footprint design saves spacing.


 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.



Welding of electronic devices, electric devices, machine parts, plastic parts, medical equipment, precision sheet metals, and extremely thin films; sealing of small devices, fine spot welding, seam welding, and cutting.
