More often than not, in freezing temperatures you will experience a reduced flow rate, even when the cylinder is completely full. A common example we give is that a full cylinder in 30° weather may read as half-full on the pressure gauge. Initial gas, air and oxygen temperature at 20oC. Stoichiometric Combustion - no excess air/oxygen. 1) MAPP gas is a mixture of various hydrocarbons, principally, methyl acetylene and propadiene.

Gas Welding Flames This neutral flame is desired for most welding operations, but in certain cases a slightly oxidizing flame, in which there is an excess of oxygen or slightly carburizing flame, in which there is an excess of acetylene is needed. Table 8-1 shows the maximum temperature achievable with these alternative fuel gases as compared with the temperature of acetylene. These other fuels work well for soldering, brazing, preheating and oxygen cutting, but are seldom used for welding. (1997).

Temperature Flame temperatures can vary as they are affected by severalfactors. Most oxygen/acetylene flames, however, measure close to 5,400°F at the end of the inner cone. Air/acetylene flames measured at a similar location typically reach 3,000°F. Acetylene and oxygen gases are used to weld and cut metal.

Oxyacetylene the only gas mixture that will burn hot enough to cut steel. Oxy-acetylene torches can easily cut through ferrous materials in excess of 200 mm (8 inches). Oxygen lances are used in scrapping operations and cut sections thicker than 200 mm (8 inches).
