Model : ML-6810C

About 35% lower consumption during the operation.
High power CW laser implements smooth surface of welding.
Available for Active Heat Control with dedicated focusing head. It enables to control the heat in processing area precisely.
Suitable for processing in automotive parts and machine parts that need high quality and high precise welding.



  • ◆ Improved brightness

    Oscillation module is optimised and brightness is improved compared with previous model.

  • ◆ Dedicated chiller

    The pairing with a dedicated chiller is needed to show its maximum ability.
    Please use chiller that our company provides.
    The chiller is delivered with it's water piping, thus a customer doesn't need to prepare it.

  • ◆ Laser power management

    Managing laser power in focal point with power meter (opotion), contributes to improvement of product quality.

  • ◆ Active Heat Control™

    Changing laser output by heat detection on axis, controls the heat input into processing area precisely.
    Suitable for welding, hardening and other application that heat control is important.
    The dedicated focusing head is needed. (Option)

  • ◆ Scanning system

    Employing the Galvo, implements high speed and high efficiency processing.
    Enables to show its superior brightness according to dedicated optical component.

  • ◆ Reflection resistant structure

    Equips a structure to restrain the reflection from workpiece, according to original optical design.
    Enables vertical emission, according to the structure which is less effect of reflection from workpiece.

  • ◆ Controlling function

    Enables to set up various wave, according to the function.
    Implements various way from high speed precise welding to cutting, according to modulation function. (frequency and waveform)

  • ◆ Saving energy and space

    Reduces energy consumption compared with previous machine, according to design optimization.
    Ensures wider space to set up machines, according to light and compact design.

  • ◆ Useful user interface

    Large LCD touchscreen allows to input setteings easily.
    Available for Japanese and English.
    Enables to use an extension calble.

 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.

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


 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.

▶ Fillet welding


Fillet welding on 0.6-mm and 1.0-mm stainless-steel materials Forms neat welding beads with sufficient strength, thereby eliminating the need for after processing.


Welding on box-type workpieces


Angle welding on box-type 0.6-mm stainless-steel workpieces Achieves bonding with little distortion.


Cross section of penetration portion


Cross section of 1.0-mm stainless-steel materials bonded by lap welding with the ML-2550AH Lap welding achieves deep penetration across each material as thick as 2 mm.
