ML-6900series
High power laser enables welding of even thick plates at a high speed and saving running costs at the same time.
More powerful version of the existing Miyachi fiber laser welders is now released. The new ML-6900A series provide the output power of up to 5kW!
High-speed CW welding becomes much faster than that by the 1kW model. It is also capable of welding thick plates. The ML-6900A series have the advantage of excellent laser oscillation efficiency, energy saving and low cost, resulting in contributing to environmentally-friendly manufacturing.
▶ Features
- ◆5kW fiber laser oscillation. High-speed welding. Welding of thick plates.
- ◆Optional two time sharing feature contributes to improvement in productivity.
- ◆High-efficiency fiber laser saves power consumption.
- ◆Easy operation with a touch screen.
- ◆Program pulse shaping, modulation control and other settings and monitor operation status without a PC.
- ◆Display power monitor, error details, status and IO monitoring on a built-in screen.
- ◆Safety shutter (by beam switch method) as standard equipment.
- ◆Monitor reflected light from a workpiece.
- ◆Long-lasting laser diode provides high reliability and reduces maintenance cost.
▶ Applications
Welding of electronic components, automotive parts, mechanical parts, plastic parts, medical equipment and precision sheet metals; sealing of minute parts; fine spot welding; high-speed seam welding; thick plate welding; etc.
▶ 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
▶ 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.
