ML-2550A – ML2551A – ML-2552A YAG Laser Welder

The ML-2550A/ML-2551A are Nd:YAG laser welders which employ the output power feedback system. They provide high power, high speed, and have excellent product quality. They can always perform stable and high-quality welding on various kind of materials.

Beautiful Finish with a Full Array of Functions

High efficiency delivery balance without power loss
The newly adopted variable mirror eliminates the laser power loss and balances out deliveries resulting in a significant improvement in beam splitting precision.Maximum of up to 4 deliveries of optical fibers can be connected (Chargeable option) either on the top side or backside of the laser unit.

Interface designed for workability
Welding initiated by an external start signal can be modified with the local controller during operation. Since the controller can be detached from the main unit, it can be operated at your hand.

* Number of schedules settings: 32

The start response time can be set in five different times within 0.1 to 16.0 ms. Also, conditions can be switched to another during the response time.

Real-time laser power feedback

  • 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
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.

High-speed, high-quality welding
High-speed seam welding is possible with high repetition rate of up to 500 pps. Also, power feedback control and waveform control functions enable high-quality welding for a variety of work-pieces.

Operation section controller
The controller can be taken off the main unit and operated by hand.

Supports factory automation easily
These devices are equipped with a wealth of input/output terminals (signals), so they can be easily connected to automatic equipment.

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

This device is for high-speed seam welding using SI type 0.3 micron optical fiber as standard.
