Regulator is a pressure control tool functions to determine the cylinder fill pressure, reduce the fill pressure to working pressure, determine the working pressure, maintain the working pressure to remain constant (constant) even though the fill pressure changes.
There are two kinds of protective gas regulators to regulate the amount of gas used in welding, namely with a capillary system (manometer regulator), the limit for the released gas flow is indicated by a needle on the working manometer (analog), and with a valve system (measuring glass regulator), the flow limit is limited. The expelled gas is indicated by a buoyant ball.
