It is sometimes claimed by others to have special properties that defy the laws of physics.
In standard oxy-hydrogen welding (using one tank of each gas), the ratio of each gas in the mixture must be very carefully controlled before burning, as excess oxygen will result in oxidation of the metal, and excess hydrogen will result in hydrogen embrittlement.
Due to the way it is generated, Brown's gas is already in the perfect mixture required for this type of welding. Brown's welding devices use water electrolysis in a common chamber to generate a stoichiometric mixture of hydrogen and oxygen, which is then passed through a flash-back arrestor and into a burner, where it is ignited to create a flame.
This oxyhydrogen flame is also said to be superior to acetylene due to the convenience of generating the gas on demand instead of buying and transporting containers of fuel.
