CO2 Gas Supply
The CO2 shielding gas is supplied cylinders at high pressure (140 kg / cm2). Therefore pressure regulator and flow meter are connected to reduce the pressure to the required level (2 kg / cm2) and to control the flow rate of shielding gas from the cylinder. Gas hose connects the flow meters the solenoid valve. The solenoid valve, when actuated releases the shielding gas into the torch assembly.
