Review on Enhanced Precision and Efficiency with Argon Regulator Welder Welding Flowmeter by Shigg Bigbee

The sensor on the first one didn't work at all so I ordered a replacement which didn't work either. Two in a row didn't make sense, so upon closer inspection I found that both had a dented faceplate that was blocking the needle. Removed the front panel, works perfectly. The main issue was of course the incredibly thin metal used in this cheap pressure gauge, but it was a cheap instrument and now it works great.
