Real-Time Power Feedback Control YAG Laser Welder

ML-2450A, ML-2350A•AF, ML-2351A•AF
(AF indicates a forced air type.)

The ML-2350A/ML-2351A are Nd YAG laser welders that use laser power feedback. They provide high quality, high speed, and high stability output and make possible high-quality welding of various materials.

Real-time laser power feedback

•Directly input the laser power you want output

Thanks to the laser power feedback technique, laser output just as set can be reliably obtained. Also, the output laser power and output waveform are displayed on the controller's monitor.

•Automatic correction of energy fed to lamp

Since the energy fed to the lamp is automatically corrected in real time, even for laser output fluctuation factors, such as lamp deterioration and YAG rod thermal lens effect, the bother of changing the power settings is eliminated.

•Right from the first shot, laser power with waveform just as set

Right from the first shot, laser power is obtained with the waveform just as set, which eliminates the conventional need for empty shots before starting the actual welding.

Advanced waveform control functions

The waveform control functions are Fix mode, which has 3-step waveforms as the basic, and Flex mode, which can set up to 20 inflexion points and express complex waveforms. Since the optimum welding conditions can be set for various materials, blow holes and cracks can be eliminated and the welding quality improved.

Forced air cooling models

Our product line-up also includes forced air cooling models that do not use external cooling water. (ML-2350AF/ML-2351AF)

Pulse repetition rate

Welding and processing can have a maximum repetition rate of 200 pps.

High-quality welding

Power feedback control and waveform control functions ensure high-quality welding for a variety of work.

Optical fiber delivery System

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

Multiple schedule setting

Up to 32 schedules and waveform control can handle a variety of work.

Space saving, compact design

Compact design combines the laser power supply, oscillator head, and cooler in one piece of equipment. This superior design also makes it possible to handle wiring, filter replacement, etc., easily, from the front of the unit.
