i got the millermatic211 about a week ago and noticed right away the gas is leaking from the bottom port on the regulator which seems to be the pressure relief valve. based on the stamping on the back of the valve im assuming 3000psi is blow off. my c25 when full was 1900. is there any adjustment or repair that can be done on the valve ? i havent yet put any wrenches on it because i didnt want to leave a bunch of tool marks in case i have to send it back for replacement and they say i damaged it. heres photo of the bottom port and inscribed backside

Reply:I have had that happen on two different flow meters....one it took just a little turn and the leak stopped while the other kept leaking even after I tightened the fitting a bit (returned that one). There's a good chance yours just needs a little nudge, but it's not a bad idea to make a call before you try doing anything to it. That way if a bit of tightening doesn't solve the issue you already have a reason why you messed with it.Check out my bench vise website: http://mivise.comMiller Syncrowave 250DXMillermatic 350P with XR AlumaProMiller Regency 200 with 22A feeder and Spoolmatic 3Hobart Champion EliteEverlast PowerTig 210EXT
Reply:If it's leaking from that relief valve return it. Something inside is bad, maybe the diaphragm. Threaded fittings another story, I had one (Miller) that extremely tight hose fitting still had a slight leak. I put one layer of Teflon tape and it holds gas for days on end. Some times the treads are just not perfect.Ernie F.
