OXYPOWER
FUEL GAS AND OXYGEN
Oxygen:
The air we breathe - our life-blood - contains about 21% oxygen, 78% nitrogen and
1% argon. Only oxygen plays an active role in combustion. Oxygen is a colourless,
odour- and taste-free gas. It is extracted from air by fractional distillation at low
temperature. Oxygen cannot be liquefied under pressure; it is a permanent gas,
which is why the oxygen in your equipment, contained in a steel bottle pressurised
to 200 bar at 15°C, is gaseous. The oxygen regulator lowers the pressure of 200
bar to the working pressure, which operates the welding torch under impeccable
safety conditions.
This explains the precautions to be taken with the oxygen and the superiority of
the OXYPOWER® performances over air-fuel welding torches (welding torches
supplied by a single hose).
Butane/Propane:
Butane/propane is a petroleum gas liquefied under pressure at ambient tempera-
ture.
Liquid butane/propane and gaseous butane/propane are normally both found in
the cartridges; for this reason you should use the butane/cartridge vertically to
draw out the gas rather than the liquid, which would affect the welding torch ope-
ration.
When gaseous butane/propane is drawn out, some of the liquid moves into the
gaseous state to re-establish the pressure. This vaporisation may cause the car-
tridge temperature to drop without however affecting its operation.
Butane/propane is a mix with a very high calorific power. This very high tempera-
ture and the concentration of the pilot flame cone is ideal for autogeneous welding
of steels up to 2 to 3 mm thick (without filler metal), which has only been possible
with oxy-acetylene or oxy-kyrene equipment until now.
