Review on WX 55X 2L Regulator Pressure Measuring 0 4000PSi by Athenasby Whitney

So I just hooked it up to my argon tank and can use it for about an hour. I've only used the left socket, not both yet. I have no way of measuring performance other than the amount of gas expelled at the settings I used had adequate gas shielding. The sensor appears to be well made, except that the nut that screws into the bottle seems a bit loose. The pitch is correct, but the diameter allows for a lot of misalignment, enough that I don't want to tighten the nut as usual. I hope reusing doesn't ruin the thread. 1 week later: I put the regulator on the next bottle and it didn't close. When tightened several times, the nut broke off. The diameter of the main thread is about 0.7mm smaller than the nut size, which I think fits and fits well. In any case, I managed to unscrew the fitting on the bottle and replace the nut with a nut from the only regulator I had. Then the bottle fits well. I also used the correct regulator (for both forward shielding gas and backflush) and now have more experience with both. They're a bit irritable, so it's difficult to regulate the flow, although it seems to stay constant when you're not pressing the button. By the way, I'm in the USA and use commercially available gas cylinders.
