CO2 Argon Flow Meter is a device used to measure and control the flow rate of a gas mixture containing both carbon dioxide (CO2) and argon (Ar). It typically consists of a calibrated tube or chamber with a float or indicator that moves in response to the flow of gas through the meter. This ensures that the correct ratio of gases is delivered to the welding torch for optimal welding performance and gas efficiency. They are compatible with gas cylinders containing mixed gas blends of CO2 and argon. CO2 Argon Flow Meter is a valuable tool for monitoring and controlling the flow rate of mixed gas blends containing carbon dioxide and argon in welding applications.
