RX WELD Argon Regulator Flowmeter Gas Gauge for Mig Tig Weld with Gas Welding Hose

I'm not a pro welder. If you're looking for such opinions, skip mine.I'm a home-jobber, hobby-welder. I needed a flow meter to get my mig setup to do aluminum wire. This flow meter attached just fine to my argon bottle, no issues. The hose it came with is fine too. I detected no leaks once it was all snugged up (I just used soapy water spray).I have no way to test if the flow-rate I'm setting is accurate. I used settings I found on-line (~15 to 20 ft/min), did my aluminum migging and the parts were joined. My welds don't look great, but it worked... my destructive testing tells me the welds are at least as strong as the base metal (aluminum angle).What I could notice was I didn't get the ugly porosity that low/no shielding gas would show. So, as far as I know, the flow-meter is passing out enough gas to do the job. Maybe its too much?.. no idea. More may be a waste than 'the right amount', but the welds are cleaner than if it was too low.I tested the low/no shielding gas use-case just so I could see what it looks like... and its very ugly. Look online for pics/vids of bad shielding on aluminum welds... its unmistakable when you see it. Now, when I say 'ugly', I mean beyond the clumpy, uneven welds a home-jobber like me puts down... b/c my welds are 'ugly'. I don't stack dimes,... I may lay down a dime, then a quarter, then a nickel... repeatedly. Bad form, bad movement control, all the wrong stuff. So, what I mean is, the low-shielding-gas issues present as pits/pot-holes and dirty/dark spots in the weld... that would make even an otherwise pro-welder's nice 'dime-stack' look like a pitted, dusky looking mess. Once you've seen it, you know what to look for.Despite my good results, I'd say that any pro is not going to use or trust this 'cheap' meter, nor should they. If your welding is mission-critical and/or lives are on the line, use the good stuff... and any pro welder knows that anyway.If you're like me and just need to stick some metal together for small projects where if they fail no one dies?.. then perhaps this flow-meter is just fine for you as well.

This regulator works great for my mig 200 5 in one mig welder. The quality is very good and the gages are easy to read. I loke the floating ball design that is easy to see. Overall this regulator is a great value for the price.

No issues! Works as intended. Easy to set up. Good build quality.

I have used the regulator only once, but it appears to be sufficient. The package comes with a brass hose adapter and a rubber O ring. The adapter has a clear use, but not the O ring. There was no obvious place to use it, so I took a SWAG and used it at the regulator to hose connection. So far so good.I will also note that the threads between regulator and tank valve as well as the threads between hose and welder appear to be a bit on the large side. This caused me concern that I might be cross threading, but there was too much interference between male and female threads to hand tighten the joint as much as I wanted. Once started I had to use a wrench to bring the connection snug, then tighten completely. Again, so far so good.The sight glass/ball style flow meter is more reliable in my opinion as it does not rely on and springs or other gauge mechanism parts. It is simply a matter of gravity combined with ball size and gas aperture of the devise. Hopefully it will be reliable.If there is a serious drawback it would be the apparent vulnerability of the plastic flow gauge tube as it could be easily broken off with poor material handling in a crowded shop.

Very nice functioning flow meter

Great price works great

Good product

Excellent craftsmanship well made
