Pulsed fiber laser welder release of new type!NEW

High quality, high-stability, low-cost laser welding!
Model : ML-3000 Series

Adopt a new air cooling system and pulse fiber laser system. Compared with YAG laser excitation of the lamp the conventional method, and realization high-quality, significant low power consumption, low running costs and more!
In addition to the fine pulse welding, high speed CW (continuous wave) welding is possible, it supports a variety of applications. It is most suitable for the replacement of a YAG laser.
Be superior to laser oscillation efficiency, this model will contribute to the manufacturing of environmentally conscious energy-saving, low-cost

▶ Features

This welder employs a full air-cooling system, which does not use a chiller, thereby reducing operating costs

Power consumption of the pulse fiber laser is approx. 85% less than that of Nd:YAG lasers (ML-3060A/AS)

With its large energy of 60 J this pulse fiber laser welder can be used for the type of welding that was previously only achieved by Nd:YAG lasers (ML-3060A/AS)

The product lineup includes the 300 W ML-3030AS and the 150 W ML-3015AS in the same size body.

With a large output of up to 600 W, this pulse fiber laser welder can be used for high speed seam sealing

Stable output power with real-time power feedback

Consistent spot size without thermal lens effects

Pulse and CW (continuous wave oscillation) operations are available

Intuitive large color LCD touch screen panel (no PC necessary to configure settings or check operating state)

Built-in power monitor

ML-3060A/AS: Up to 4 time-sharing fiber deliveries are available. (When the isolator Option is mounted, Up to 3 time-sharing fiber deliveries are possible) 

  *ML-3030AS/3015AS: Provide 2 laser output deliveries via either time-sharing or energy sharing.

The isolation function (Option) protects the oscillator from light reflected from the processing point.

When the optional isolator is mounted, the laser power output from the fiber decreases by up to 10%.

 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.
