AMADA WELD TECH Laser Welders Direct Diode Laser Welder

120W ML-5120A

Direct Diode Laser Welder with "Active heat control™" function!

It's suitable for soldering and plastic welding applications.
Localized heating - Ideal for small parts and small spacing.

ML-5120A is a Direct Diode Laser Welder with maximum output of 120W and designed for high energy efficiency. The laser light is created directly from the diodes and does not need amplification in crystals such as Nd:YAG or Nd:YVO4. The output is directly used for thermal processing such as plastic welding and soldering applications. The Active heat control is a unique function that controls laser outputs to keep the heat input to the processing area constant according to the heat generated at the processing area detected by a coaxially-arranged heat detector.

Features
■ Features
  • Dedicated ouput unit (FOCH-30B series) is necessary for function of Active heat control. *1 

    Soldering with Active heat control

  • Energy saving
    Direct Diode Laser Welder uses a light from the highly efficient diode directly to weld parts; its power consumption can be reduced.
  • Optimal for plastic welding
    Because base materials themselves are bonded together, they can easily be recycled, thereby facilitating environmentally friendly plastic bonding. This eliminates the need to wait until the adhesive hardens, significantly reducing bonding time.
  • Suitable for laser soldering
    The small spot diameter of 0.2 mm allows for fine soldering in high-density, small-pitch areas and small areas. In addition, Direct Diode Laser Welder can perform environmentally friendly lead-free soldering.
  • Optical fiber delivery system
    Optical fiber delivery systems with Two energy-sharing deliveries are available. *2
    Energy outputs improve productivity.
  • Power monitor as a standard equipment

*1. No guarantee for the result.
This enables to maintain adequete heat input by controling laser power.
*2. Active heat control is available for either output when using energy share outputs.
*3. This product is subject to Japanese Export Control Law. Depending on its destination, prior assessment and authorization may be required. When exporting from country of initial purchase destination, please be sure to follow that country's export regulations as it may require an export permit beforehand.Details would like to ask you to inquire to business about it.

Standard Features

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.

Real-time Power Feedback Control

Standard Features

Waveform control

Equipped with a "fixed mode" that features three-level waveforms, and a "flex mode" to provide more complex waveforms.
Waveform control

Standard Features

Power monitor

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

Standard Features

Color LCD touch panel

The touch panel can be detached from the main unit and operated by hand.

Color LCD touch panel

Standard Features

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

Standard Features

Fade-in/Fade-out

This feature avoids marks at the end of seam welding and provides a beautiful finish even for overlapping circumference seam welding sections.

Fade-in/Fade-out

Standard Features

Forced Air Cooling System

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