RIVERWELDArgon Gas Flow Meter Scale Tester Measure Flowmeter for TIG Welder Welding

Learning to TIG weld, and things were not going well. After purchasing this, I discovered that what my on-tank flow meter said, and what was coming out of my torch were vastly different.I set my flow rate using this device, and TIG welding all of a sudden became SO easy. By far the best money I have spent on welding supplies. Trust, BUT verify........ (I put a piece of masking tape on the scale of my flow meter, and marked it correctly based on what was coming out of my torch.)

As you can see from my pictures, the ball jams in the bottom of the tapered tube. While the ball is 7.9mm diameter, the bottom of the tube is 7.4mm, while the top is 9 mm. Here is the fix: 1)cut a small piece of plastic or metal tubing 5-7mm outside diameter, or stack some small washers to acheive the same. Make certain the spacer or tubing you choose, does not block the exit air hole of the black rubber adapter cone. 2) Using a drill bit or something else with appropriate dimensions, insert your spacer(s) into the bottom of the tube. It will keep the ball from falling too low into the tapering, where it will jam. 3) Reassemble the upper vented plug and the lower tapered rubber cone, onto the plastic flow tube. Done.

Junk. Bought 2 one doesn't work because ball is stuck all the time. Other one is abt 10 CFM off. On my part o didn't realize they weren't measured in CFM but they refused my refund within minutes ilof ordering. They said product had been shipped. Yeah right

Its a nice tool to have around when you are checking your argon ga vrs what you are getting at the torch end.

When I first tried it the bann was stuck. I had to manually moveit to get it to work. Once freed it it appeared to work.

Great price ! Works without any hassle !

I used someone’s flow gauge at work (different brand) and thought it was something useful to have so I ordered this one. It’s very cheaply made especially compared to the one I used at work. It’s better than nothing I guess. The ball gets stuck in the bottom of the tube so you have to get that loose before testing gas flow. Feels like this wants to come apart really easy too

The ball likes to get stuck in the bottom and will not indicate flow.It reads several CFH lower than the flow meter on my Miller so the question comes up - - which one is right?Since the ball loves to stay stuck in the bottom I am going to keep trusting what the Miller gauge tells me and scrap this thing.
