◆Welding with a few heat-affected area can be done due to that laser welding is "contactless" welding.

◆Real-time Power Feedback feature ensures stable welding under optimum weld conditions.

◆Employing an optical fiber makes its automation easy.

◆High power oscillator enables high speed seam welding.

◆Up to four energy sharing.

◆Controller is detachable.

▶ 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.

▶ Variable mirrors

These mirrors eliminate laser power loss and improve branch balance.

▶ 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.

▶ Controller

The controller can be detached from the main unit to operate at your 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.
