Risk of poisoning by toxic solvents when methanol-containing
vapourizer liquids are used!
Do not inhale the vapours!
Avoid contact with eyes and skin!
Wear protective gloves and goggles when handling hazardous
substances! Do not eat, drink or smoke!
Observe the specific safety warnings given on the label of the
vapourizer liquid used. Some types of vapourizer liquids may be
toxic!
Store open containers of vapourizer liquid that are not yet
empty at a safe place and keep out of reach of unauthorized
persons, in particular of children.
CAUTION!
The maximum temperature of the hydrogen-oxygen flame is
approx. 2850
o
C. It is typical that the pure detonating gas flame
is almost invisible and the flame temperature is too high for
many applications. Therefore, the gas is guided through a
vapourizer liquid to reduce the energy density (flame
temperature). With Redux the temperature of the falme is
reduced to approx. 1800°C. In the same process the flame
becomes coloured which is desirable with a view to labour
protection.
For melting or soldering e.g. of platinum the flame does not
have to be enriched by vapourizer liquid. For these applications,
the vapourizer liquid can be removed from the vapourizer glass.
The high flame temperature which is necessary for the
soldering of platinum can also be reached by the use of water in
the vapourizer glass. The cleanness of the gas is improved
through the filtering effect of the water which allows the fast and
high-energy burning of pure hydrogen-oxygen mixture.
1. Open the closing cap of the vapourizer glass ( see
illustration 5.4.A .).
How to proceed
2. Place the clean funnel (delivered with the unit) into the
fillling opening of the vapourizer glass.
3. Carefully fill vapourizer liquid into the vapourizer glass up to
the red maximum filling level marking ( see illustration
5.4.B .).
4. Screw the closing cap back onto the filling opening and
tighten.
5. The filling process is now finished.
