Argon Co2 Professional Gas Flow Meter Tester Flowmeter (peashooter) for Mig Tig Welder Welding

It works as it should and seems decent quality... I would recommend.

Works well

When your welding (MIG or TIG) it nice to know the actual gas pressure at the torch. Generally it’s the same with good welding equipment, but never hurts to be sure. This inexpensive product handles the task.

Everyone should have this ! The price is great, I saved the cost in the first 4mins.

I heard these are not accurate, but that doesn't matter to me. I used the markings on this that works for me and use it to setup the next weld machine to it. Even regulators are not exact compare to each other

Using this for Argon which all of the standard flow meters used in the US measure the gas in CFH. But the only tool to verify what's coming out of the nozzle measures in LPM. Yeah, this one. Seriously. Why not put an imperial scale on the other side of the glass for CFH - like my tape measure, yard stick, machinist's rule, kitchen measuring cups, car speedometers, tire gauges, etc. Other than that, it seems to work 'okay'. It's difficult to read because the glass is clear and the scale is printed in black, making it difficult to see the numbers. Can I trust the reading in LPM? How do I verify that's correct?!

Beats looking at the flow gauge on the tank

I used this flow gauge to find a problem with my new MIG torch. I found the torch liner was pushed in too far and was restricting the gas flow. The gauge at the gas bottle said everything was OK when it was actually reading high. It’s the flow AT THE TORCH that matters!! This is such a simple and inexpensive tool that every welder should have one.
