Lixys has developed and will commercialize a new generation of welding masks based on a new mode of vision, the synchronized vision.




In most of the modern welding source arcs are operated through pulsed currents. The innovation developed by TELECOM Bretagne and Lixys is a fast liquid crystal filter that allows a real time following of the light pulses induced by the pulsed arc current.
Lixys liquid crystal filter is about fifty times faster than a liquid crystal flat panel display.
 

Lixys welding mask main advantages:
- decrease of the welder fatigue during pulse welding
- clearer vision for low frequency (<30Hz) pulse welding

Lixys welding mask is compatible to constant current welding.

Lixys autodarkening filter response during pulse synchronization : perfect following between light and filter transmission

Lixys has completed recently a prototype and has tested it at the Institut de Soudure (Welding Institute, Paris). This prototype includes a fast shutter at a standard size for welding masks (10x5cm), a nematic cell (combination patented) and an optical sensor to detect light pulses. A paper has been published in the journal “Soudage” of the Institut de Soudure. The potential of Lixys innovation has been  validated by this test.
