Review on Enhanced Precision and Control with Western Enterprises VN 500 Flowmeter Regulator by Jeremy Choi

I would never admit that to any of the guys but: I've had times where I missed nitro soldering, only to pressure test and found a leak and had to redo it . Then fret and weld without nitro (shame). To explain. If you don't have such a thing, you'll need to set the regulator to <100psi, then remove the hose and attach the flow regulator to the bottom. to 3-6 psi, then make sure it is flowing properly, weld, remove the hose, remove the flow sensor, reconnect the hose and check the pressure again. Or you can click away from soldering to search for soldering. The whole company wants to switch to it. Bonus, it's less than your psi output and tank psi controls.
