In standard ] (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 ] of the metal, and excess hydrogen will result in ].<ref name="US4014777">{{US patent reference |

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 ] in a common chamber to generate a ] 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.<ref name="US4014777"/> |
|
|
|
|
|
This ] is also more convenient than fuels like ] due to the generation of gas on demand instead of buying and transporting containers of fuel. Brown's gas generators only require a source of water and electrical energy.<ref name="US4014777"/> |

=== Safety === |
|
|
|
|
|
The gases are usually kept in separate tanks due to the danger of explosion if they are ignited inside a tank or device. Brown includes a number of safety devices, however, such as porous plugs that allow gas through but not the heat of a flame, and claims that his welding device is safe.<ref name="US4014777"/> |

|
|
=== Atomic welding === |
|
|
|
|
|
Brown also describes "atomic welding" in his patents, in which an ] is passed through the mixture of gas before burning, so that the gas molecules break into atomic oxygen and hydrogen before recombining, producing a hotter flame ("218,000 cal. per gram mole").<ref name="US4014777"/> |
