The safety pressure regulation system is installed close to the tank.
It provides for uniform pressure in the network. The built-in pressure relief
valve ensures that the gases are released outside in case of accident.
This helps avoid any endangerment in the area around the laser machine
due to concentration of oxygen (O
2
) or depletion of oxygen (N
2
).
10
The machine is equipped with blow-off valves that respond when there is
high input pressure, thereby creating a whistling sound.
11
The volume rate of flow is reached when selecting maximum cutting gas
pressure and specifying nozzle diameter.
