Tests [citation needed] showed that an oxy-gasoline torch can cut steel plate up to 0.5 in (13 mm) thick at the same rate as oxy-acetylene. In plate thicknesses greater than 0.5 in (13 mm) the cutting rate was better than that of oxy-acetylene; at 4.5 in (110 mm) it was three times faster. [10]

Nineteenth century examples of dry and wet types of flashback arrestors, for use with oxy-hydrogen. Flashback arrestors with different size and flow rate, and different connections A flashback arrestor or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up ...
A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.
The investigation by the Civil Aeronautics Board discovered that a fuel leak in the port engine's fuel pump had ignited and the slipstream fanned the flames to a white hot intensity. The ensuing fire, acting like an oxy-acetylene torch, burned through the wingspar and caused the crash. [3] [4] [5] A DC-3 similar to the accident aircraft
Reducing, neutral and oxidizing oxyacetylene flames. A flame is affected by the fuel introduced and the oxygen available. A flame with a balanced oxygen-fuel ratio is called a neutral flame.
Modern versions of differential hardening were developed when sources of rapidly heating the metal were devised, such as an oxy-acetylene torch or induction heating. With flame hardening and induction hardening techniques, the steel is quickly heated to red-hot in a localized area and then quenched. This hardens only part of the object, but ...
The torch used for lead burning is a small, hot, gas flame. Oxy-acetylene is most commonly used, as it is easily portable. A small size #0 nozzle is usually used, sometimes with a miniature torch body, but the torch is otherwise the same as that used for steel or copper work.
