The industrial gas used for fueling torches is Mapp gas. The Dow Chemical Company developed this gas mixture. The gas serves as an alternative to acetylene. The storage of this gas is comparable to that of LPG and this makes it highly favorable with hobby welders. Mapp gas torches produce a flame of an extremely high temperature. This means that the gas is ideal for industrial metal-cutting operations. Torches which use Mapp are not recommended for use in the welding of steel as Mapp contains a large quantity of hydrogen and this may result in steel welds which are generally poor and brittle in quality.
A gas torch should always be used with the greatest of caution. When lighting a gas welding torch, extreme care should be taken. Gas torches should never be used without the correct equipment. The correct type of protective clothing should be worn. This includes a helmet and gloves. This type of gas is one of the safest gas mixtures for both recreational welders and hobbyists to use and store. However, it can also be used for high-volume cutting operations due to its high pressures.
Mapp Gas
Mapp gas, as has been stated, reaches high combustion temperatures. This makes it outstanding for heating, brazing and soldering. These high temperatures render this gas invaluable for a whole manner of projects involving welding and cutting. The correct type of setup will enable an individual to perform a wide variety of welding operations in their own homes.
The use of Mapp in cutting underwater has proved successful. However, the use of Mapp in cutting underwater has been largely succeeded by exothermic cutting which is both faster and safer than the use of Mapp. Mapp is not recommended for use in steel welding. As stated above, the explanation for this is that the gas mixture contains hydrogen in high concentration. It is perfect for use in the welding of aluminum, copper and stainless steel.
In both its liquid and gaseous forms, Mapp is completely colorless. When it is in use, Mapp gives off a smell akin to that of fish odor or garlic. Mapp gas also burns hotter than all the gases.
