Booster Fluids

Methanol is the preferred booster fluid for general applications.

The user will have to do his own experimenting to find those fluids or combinations most advantageous for his specific use.

Brazing Flux Additives to Booster fluid
NOXIDE™ is a mixture of Methanol and a chemical compound acting as a brazing flux during brazing or silver soldering or fusion of gold or silver or other noble metals. Noxide™ is not for soft soldering.
NOXIDE™ and other borate based fluxes give the flame a green colour.
NOXIDE™ is used successfully by goldsmith and jewelry makers.
NOXIDE™ application also means that tips and filters must be cleaned more often.

An external gas filter GCF-900 #11807 or FGG-H-A #11803 must be used to pre-clean the SPIRFLAME gas before entering the Booster.


NOXIDE™ and ALCOHOLS are FLAMMABLE. TAKE THE NECESSARY PRECAUTIONS WHEN HANDLING SUCH FLUIDS.

Thermal Considerations of Gas Combustion

The temperature of a flame depends on the mixture ratio between the combustible gas and the Oxygen, as listed:

Hydrogen - Oxygen     3'300 °C

Spirflame® Gas
+100% Methanol     2'700 °C
