I have an exsiting 20lb aluminum CO2 tank that I use for OBA. It currently has a male output on the valve and my regulator uses a female fitting plastic type bushing to seal. Works great. The regulator gauges are PSI/PSI (pressure/pressure)

Now my welder included a regulator that is PSI/CIM (pressure/flow) and is the typical male compression type fitting.

Is there an adapter out there to go from the male tank valve to a female compression style?

It'd be nice to be able to use a single tank.

If you want to use the flowgauge that came with your welder on CO2 you can unscrew the tank fitting on the flowgauge (CGA 580) and replace it with same style fitting that is on your OBA regulator (CGA 320).

Depending on what style of flowgauge came with your welder it might not be designed and calibrated for nor work well with straight CO2.

Is this what you want? http://store.weldingdepot.com/cgi/weldingdepot/A848.html

thanks!

They should have them at Fresno o2 as well.

i think i will hit up a local supplier and jsut convert the new reg to the setup i have now and not worry about an adapter

I got my adapter at Modesto Welding Products, cost was under $10?
