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 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, by using newly equipped function of temperature control.
- Dedicated ouput unit(FOCH-30B series) is necessary for function of temperature control. *1
Soldering temperature control
◆Equipped with a power monitor as standard equipment
LD direct lasers are energy-saving devices that have low power consumption and high efficiency; they apply light emitted from LDs (laser diodes), which have good oscillation efficiency, directly to thermal processing.
◆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, LD direct lasers can perform environmentally friendly lead-free soldering.
◆Can be used with an optical fiber delivery system
Optical fiber delivery systems with 2 energy-sharing deliveries are available. *2
Energy sharing with 2 deliveries improves productivity.
- ◆Equipped with a power monitor as standard equipment
– Temperature control function screen sample –
The temperature control function detects the temperature of the processing part and stops laser when it exceeds the target temperature.
Temperature control function: No guarantee for exact temperature in focus point.
This enables to maintain adequete temperature by controling laser power.
- Temperature control function is available for one channel.
- 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.
▶ 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.
▶ 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.
▶ Forced Air Cooling System
The air cooling system is available. No water and piping are necessary.
