Operating cost for a gasoline torch is typically 75-90% less than using propane or Acetylene. The gasoline can be fed either from a pressurized tank (whose pressure can be hand-pumped or fed from a gas cylinder) or a non-pressurized tank, with the fuel being drawn into the torch by a venturi action created by the pressurized oxygen flow.

Air acetylene welding (321) AAW Chemical welding process, not popular Limited Oxyacetylene welding: 311: OAW Combustion of acetylene with oxygen produces high-temperature flame, inexpensive equipment Maintenance, repair Oxygen/Propane welding 312: Gas welding with oxygen/propane flame Oxyhydrogen welding: 313: OHW
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.

Oxyfuel uses oxygen as a primary ignition source in tandem with another gas such as acetylene to produce a flame which is 2500 °C at the tip and 2800-3500 °C at the tip of the inner cone. [7] Other gasses such as propane and methanol can be used for oxyfuel welding. Acetylene is the most common gas used in oxyfuel welding.
The balanced equation shows to use 1 mole of propane for every 5 moles of oxygen. With air/fuel torches, since air contains about 21% oxygen, a very large ratio of air to fuel must be used to obtain the maximum flame temperature with air. If the propane does not receive enough oxygen, some of the carbon from the propane is left unburned.

C-50 (50% argon/50% CO 2) is used for short arc welding of pipes, C-40 (60% argon/40% CO 2) is used for some flux-cored arc welding cases. Better weld penetration than C-25. C-25 (75% argon/25% CO 2) is commonly used by hobbyists and in small-scale production. Limited to short circuit and globular transfer welding.
