This Meanlin Measure argon regulator and flow meter is a brass, CGA 580 regulator marketed for TIG and MIG welding gas control. Based on the Amazon listing, it suits hobby and small-shop welders who need an argon regulator with two gauges and a hose included. Skip it if you run CO2 or a different cylinder type, and verify the listing details before buying.

What It Is and Who It Suits
An argon regulator reduces high cylinder pressure to a steady working flow for your torch or wire feeder. The flow meter part tells you how fast gas is leaving, usually in cubic feet per hour or liters per minute. This model is sold as a combined unit with two gauges and a hose, so it is a simple bolt-on upgrade for a basic gas setup.
It is best for hobbyists, home garages and light fabrication where argon is used for TIG or for aluminum MIG. A busy production shop may prefer a regulator from an established welding supplier with known repair parts and a documented warranty.
How to Check It Fits Your Setup
- Cylinder: CGA 580 matches typical US argon and inert gas cylinders. CO2 cylinders use a different fitting, and oxygen and acetylene regulators are different again.
- Outlet: The 5/8 in-18 RH outlet is common on gas hoses. Confirm that your welder or torch hose uses the same nut, or whether you need a barbed fitting.
- Dual output: The title mentions dual outputs. Read the listing images to see whether that means two outlets or two readouts, and whether both outlets share a single flow setting.
- Flow scale: Check the units and the range printed on the flow meter. TIG often needs low flow and fine adjustment, and a scale that runs far above your needs can make setting precise flow harder.
- Pressure rating: A cylinder gauge range up to 4500 PSI covers full argon cylinders, but check that the gauge face is clear and the markings are readable.
Pros and Limitations
Pros
- Brass construction with a standard inert-gas inlet.
- Hose included, which can save a separate purchase.
- Dual gauges make it easy to see cylinder content and flow at a glance.
Limitations
- Meant for argon, not a universal regulator.
- Brand has limited service history, so there is little published support information.
- No spec given in the listing for flow accuracy, so do not treat the dial as a calibrated lab instrument.
Setup and Safety Tips
- Crack the cylinder valve briefly to blow out dust before fitting the regulator.
- Fit the regulator with the adjusting screw backed out, tighten the nut with a proper wrench, and then open the cylinder valve slowly.
- Stand beside the gauges, not in front, in case a gauge fails.
- Check for leaks with soapy water, since a slow leak can empty a cylinder overnight.
- Chain the cylinder upright and cap it when moving it.
- Close the cylinder valve at the end of the day and bleed the line so the regulator is not left under pressure.

Frequently Asked Questions
Can I use the Meanlin argon regulator for CO2 or argon/CO2 mix?
Argon regulators and flow meters are normally set up for argon and argon blends, and the listing describes this one for argon. For CO2 or 75/25 mix, confirm with the seller that the unit is rated for that gas, and note that CO2 regulators often differ in inlet fitting.
What cylinder connection does it use?
The listing gives a CGA 580 inlet, which is the standard connection for argon, helium and other inert gas cylinders in the US. The outlet is listed as 5/8 in-18 RH. If your cylinder is a different gas type or a non-US fitting, an adapter will not make it safe.
How much argon flow do I need for TIG?
Many TIG setups run somewhere around 10 to 25 cubic feet per hour depending on cup size, joint and drafts, but this varies. Start with the welder or torch maker guidance, then adjust. Too little flow causes porosity, and too much wastes gas and can create turbulence.
How do I check for leaks after installing it?
Open the cylinder valve slowly, then spray soapy water on the inlet nut, outlet fitting and hose ends. Bubbles show a leak. Tighten gently or reseat the washer, and never use oil or thread tape on gas regulator seats.
Verdict
The Meanlin unit looks like a practical argon regulator for home TIG or aluminum MIG if the CGA 580 inlet and the outlet fitting match your gear. Check the listing for the flow scale and warranty before ordering.
