Welding O2 and Demand Valve (Read 1133 times)

MPMIII CH.com Veteran Offline Posts: 112 Alabama Gender:	Welding O2 and Demand Valve May 16^th, 2012 at 9:44am Does any one use the demand valve system with a welding tank? I use an M tank with a welding regulator and optimask (pic below). I am going to buy a demand valve, but did not know if I would need to buy a new regulator. Any tips would be appreciated. Thanks. Regards, Malcom

You will need a 540 CGA regulator with a DISS fitting for the demand valve, these will fit your tank. I got mine from Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to

, $162, made in the US.

Also check Ebay as many folks find regs there for much cheaper. I'm not up on welding regs but you may be able to get a DISS fitting for yours.??

With the reg I have, I can use either the O2PTI or the demand, both are hook up.

I have the very same regulator you have pictured. All you have to do is unscrew the nipple (where your O₂ptimask is connected), attach the demand hose to it, and turn the flow up to a level that will give you as much O2 as you need for each breath. No need for a new regulator.

I think that depends on your abort style. Several of us use a deep breathe and hold style. For me, the demand valve is perfect because as the abort progresses, I'm holding my breath for 30 seconds at a time or better. I average 6-8 aborts per E-tank, basically 3-400 pounds of 02.

My guess is for those that use the extreme hyper-ventilation method there wouldn't be as much of a savings on 02 use, but that's just Joe's uneducated guess, your mileage may vary! Wink
