• ML-6040A


Air-cooling fiber laser welder for fine welding is released!

High peak power!

High power density!

High quality fine welding!
Model : ML-6040A


◆AMADA MIYACHI’s own-developed high-quality fiber laser oscillator.

◆Fewer heat-affected area.

◆40W average rated power and 80W peak power. Various workpieces from thin stainless steel foils to 100μm or less-thick plates layered can be welded.

◆Suited for small-spot soldering.

Φ50μm optical fiber enables high quality fine welding.

◆Efficient fiber laser reduces environmental burden and CO2 emissions. (Power consumption is approximately 60% lesser than that of AMADA MIYACHI’s lamp-pumped laser welder.)

◆Long-life LD reduces maintenance cost.

◆Fully air-cooled model, which is the first in AMADA MIYACHI’s fiber laser welder series, reduces initial costs and running costs.

◆Power feedback feature.

◆Built-in power monitor for better quality control.

◆CDRH certified.

 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.
