MAPP GAS With Torch Attachment by Starke HVACR. However, for the small-scale user a MAPP/oxygen flame is still highly desirable, having higher flame temperatures and energy densities than any flame other than acetylene/oxygen, but without the dangers and inconveniences of acetylene/oxygen.
MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel. Other welding gases that develop comparable temperatures need special procedures for safe shipping and handling.
A propane torch is a tool normally used for the application of flame or heat which uses propane, a hydrocarbon gas, for its fuel and ambient air as its combustion medium. Propane is one of a group of by-products of the natural gas and petroleum industries known as liquefied petroleum gas (LPG).
The term "blowtorch" is commonly misused as a name for any metalworking torch, but properly describes the pressurized liquid fuel torches that predate the common use of pressurized fuel gas cylinders. Torches are available in a vast range of size and output power. The term "blowtorch" applies to the obsolescent style of smaller liquid fuel torches.
Most artists today use torches that burn either propane or natural gas, or in some countries butane, for the fuel gas, mixed with either air or pure oxygen as the oxidizer. Many hobbyists use MAPP gas in portable canisters for fuel and some use oxygen concentrators as a source of continuous oxygen.
This is especially important since MAPP gas is no longer produced. Wizard191 18:31, 21 August 2010 (UTC) Is there any proof that this is not the common name? "Methylacetylene-propadiene gas" gets 47 hits and "MAPP gas" gets 42,000. Vegaswikian 18:53, 30 August 2010 (UTC) "MAPP gas" is definitely more common, however, its a trademarked name that ...
