Flowmeter aga

Gas test flow gauge for gas arc welding, for argon and argon mixtures with carbon dioxide. The flow meter tube is held vertically, tightly against the gas cap on the welding gun. The gas flow is read at the centre of the ball according to a graded scale of 5-25 l/min. Gas flow for gas arc welding always refers to the flow in the gas nozzle. Depending on the quality and condition of the hose and the welding gun, the flow in the gas nozzle can be significantly less than the value displayed on the flask regulator.
