What is the most gas-saving gas meter for argon arc welding?

There is no argon meter that saves the most gas and wastes the most gas! It's all the same. The barometer is neither a gas gauge nor a gas gauge. The barometer is only used to show how much gas is left in the cylinder. When the barometer shows little gas, you should send the gas to argon company. In order not to delay production efficiency, you should be prepared! Factories are like this! With the different thickness of argon arc welding material, the gas size is also different. If the material is thin, turn down the gas to avoid wasting it. If it is too small, it will save fuel. But it is not easy to weld, and the welding quality cannot be guaranteed!
