Torch and Oxycon settings
 

Can anyone offer me the recommendations for amount of lpms on a 20 lpm oxycon? and the setting for propane. I am running a 20 lpm oxycon and bottled propane. Also working on a Nortel Mega Minor I think my settings (for soft glass) do not work for boro. Newbie here with boro. TIA

Basically you want to run it as high as you can without purity suffering. At least 10-12 minimum.

Thasnks Cosmo, How about the psi on the propane? Is 5 sufficient?

That should be fine

Thanks again Cosmo, your input greatly appreciated.

The concentrator manual will list the oxygen purity at various LPMs. The general rule of thump, as pointed out above, is to set less than maximum.

In most cases, unless the torch is raged, the actual LMP going to the torch will be restricted by the torch oxygen value setting.
