OYHBO Argon/CO2 Mig Tig Flow Meter Gas Regulator Welding Weld Dual Output CGA-580 Inlet

It works great because I have 2 TIG welders sharing the same gas supply. No downsides or problems. I would recommend and buy again if necessary.

First glitches: 1.- The wrench size for the bottle nut is 1-1/16, NOT the standard 1-1/8. (minor). 2.- The bottle connection required multiple attempts and a HUGE amount of torque to finally seal, same bottle that other regulators seal easily on. (not really *minor*). 3.- MAJOR Fail: after two days of use, discovered that plastic of BOTH flow meters was 'crazed' with tiny cracks on the INside with what looked to be a chemical incompatibility(?) as if the plastic used is attacked by argon? After a short while, the cracks broke through and of course argon was leaking out. (Catastrophic fail). I don't know 100% whether the plastic or possibly this one bottle of argon is responsible (contaminated? maybe) It's fresh from the gas place last week but now it's empty so cant really know, I guess...but I'm NOT buying another OYHBO unit.
