Flowmeter Regulators have proven performance in MIG Welding and TIG Welding applications. Here the outlet gauge is replaced with flow calibrated gauge to show flow rate in lit/min. This eliminates additional glass flow meter, which prone to get damaged. 1. Safety valve 2. Plenum chamber 3. Captive P.A. knob- Can not be lost of change with unsuitable type. 4.
