Molten Weld

A CO2 regulator with a flow meter is a specific type of pressure regulation device used to control the flow of carbon dioxide gas from a cylinder for applications such as MIG welding, aquarium CO2 injection, or beverage carbonation. 
Key Features

• Dual Gauges: Similar to other gas regulators, these units typically feature two indicators: a high-pressure gauge showing the remaining pressure in the cylinder (e.g., 0-3000 PSI) and a flow meter (a tube-style "peashooter" with a floating ball) showing the actual gas flow rate in units like Liters Per Minute (LPM) or Cubic Feet per Hour (CFH).
• CGA-320 Inlet Connection: CO2 regulators use a specific CGA-320 inlet fitting to connect securely to a standard CO2 gas cylinder. This is different from the CGA-580 connection used for inert gases like argon or helium.
• Pre-Heater (Common in Welding): A significant feature of many CO2 regulators for industrial welding is an integrated electric pre-heater (available in 36V or 220V options). As CO2 is drawn from the cylinder at high flow rates, it expands rapidly and can cause the regulator to freeze up due to the Joule-Thomson effect. The heater prevents this freezing to ensure a smooth, uninterrupted gas flow.
• Durable Construction: They are generally made from robust materials like forged brass or copper to withstand high pressures and demanding environments.
• Precise Adjustment: An adjustment knob allows for accurate control of the output flow rate, which is crucial for optimal results in different applications.
