I set up an oxygen / natural gas system in my old workshop some
twenty five years ago. We had a large oxy cylinder in the corner of
the workshop. The pressure on the natural gas is not important as
the oxy pressure gives the flame pressure. You have to buy de
greased copper tubing and fittings for the oxygen line, this is very
important as the reaction between oxygen and grease can be explosive
when added to gas and ignited. All joints in the copper pipe must be
soldered with silver solder, not lead based solder. You only two
flash back arrestors, one in each line at the end of the bench
before the gas inputs. The torches we used had small one way valves
in the gas lines also for added safety. You will need an oxygen
pressure regulator on the oxy bottle, one with two dials, one tells
you how much oxy in the cylinder and the ofher is adjustable to
change the pressure to the torches, so that you can have fierce or
I now use an oxy propane set up in my small workshop so I have to
use a regulator on the propane bottle also, but this is to cut down
the gas pressure from the propane bottle.
I hope this all makes sense.
If you need to know any more please contact me. I have
fitted two workshop systems like this in my 44 years in the trade.
