ML-2350A_ML-2351A_ML-2350AF_ML-2351AF_ML-2450A

Air Cooling systems are now available!
Model : ML-2350AAF_ ML-2351AAF_ ML-2450A

Welding with a few heat-affected area can be done due to that laser welding is "contactless" welding.

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

Employing an optical fiber makes its automation easy.

Two cooling systems are available. Water cooling and air cooling.

Up to six energy sharing.

Controller is detachable.

▶ Real-time Power Feedback Control

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.

▶ Variable mirrors

These mirrors eliminate laser power loss and improve branch balance.

▶ 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.

▶ Controller

The controller can be detached from the main unit to operate at your 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

▶ Fade-in/Fade-out

This feature avoids marks at the end of seam welding and provides a beautifu13-en.png

l finish even for overlapping circumference seam welding sections.


▶ Forced Air Cooling System

The air cooling system is available. No water and piping are necessary.

▶ Hybrid Laser Welding System

This system combines SHG green laser (ML-8150A) and the fundamental laser (ML-2000 series) at the focus unit to obtain improved welding depth and spot diameter.

 Real-time Power Feedback Feature

  • What you set is what you get

    Thanks to the output power feedback system, the exact laser output power can be obtained just as you set on the unit. In addition, the output power and output waveform are displayed on the controller's monitor.

  • Automatic correction of the pumping energy

    Since the energy fed to the lamp is automatically corrected, there is no need for bothersome adjustment, even thought the laser output would be fluctuated caused by some reasons, such as lamp's deterioration and thermal lens effect on the YAG rod.

  • The configured output power with the waveform will be provided just as set from the first shot

    Since the desired laser output in the right waveform is applied to the work from the first shot, there is no need for "warming-up" shots before the actual welding.

▶ Advanced waveform control functions

50w_img06-en.jpg

With the waveform control functions there are two modes, Fix mode which is based on a 3-step waveforms, and Flex mode where you can set up to 20 inflexion points to create complex waveforms. Since the optimum welding schedules can be set depending on the various materials, blow holes and cracks can be avoided and the welding quality will be improved.

▶ Air cooling system

Air cooling system is employed for ML-2350AF and ML-2351AF. No piping, water, and chiller are necessary and the initial cost and running cost can be reduced.

▶ Small footprint

A laser power supply, an oscillator, and a cooler are all integrated into one compactly designed unit.

▶ Optical fiber delivery system

A maximum of four branches are possible, including energy sharing and time sharing. (Optional)
