They are accessories intended to reduce the high variable cylinder pressure at a working pressure suitable for welding and keep that pressure constant during the process. The high pressure gauge marks the gas content contained in the cylinder; The low pressure mark marks the required working pressure, which is regulated according to the nozzle and the base material to be used. The safety valve allows the gas to escape in case of overpressure.
Adjusting screw
Server to set the working pressure. As you rotate clockwise, the pressure on the low pressure gauge rises. In the opposite direction, the working pressure will decrease.
