Meet Tomorrow’s Laser Technology Challenges With WITT!

Lasers are being incorporated into metal machining processes more and more, such as welding and cutting.
The economic use of lasers is determined by two factors: First, optimum productivity and use of the system and secondly, consistently high quality performance. Both are distinctly affected by the composition of the gas mixtures used. WITT gas mixers guarantee optimum laser performance.
WITT. For a clean cut!
Developing laser gas mixers does not just mean that the required quantities of the gas blend are provided reliably when needed and in the required composition. In addition, the gas cleanness must not be compromised. WITT gas mixers are optimised to prevent contamination of the gases through their flow path from the storage cylinder into the resonator cavity of the laser system.
One of the lasers types most commonly used for material processing is the CO2Â laser. These lasers operate using gas mixtures consisting of CO2, N2Â and He as service (lasing) gas. The laser beam is generated by excitation and subsequent discharge of the CO2Â molecules. The N2Â portion in the gas mixture supports the energy transfer to the CO2Â molecules, while He added to the gas mixture enhances heat dissipation.
