Acetylene is a colorless, combustible gas with a distinctive odor. When acetylene is liquefied, compressed, heated, or mixed with air, it becomes highly explosive. As a result special precautions are required during its production and handling. Acetylene is utilized for oxyacetylene gas welding and cutting due to the high temperature of the flame; combustion of acetylene with oxygen produces a flame of over 3600 K (3300 °C, 6000 °F), releasing 11.8 kJ/g. Oxyacetylene is the hottest burning common fuel gas.

Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily non-reactive substances become reactive. There are several different reasons argon is used in particular applications:

  • An inert gas is needed. In particular, argon is the cheapest alternative when nitrogen is not sufficiently inert.
  • Low thermal conductivity is required.
  • The electronic properties (ionization and/or the emission spectrum) are necessary.

Nitrogen gas has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable;

As a modified atmosphere, pure or mixed with carbon dioxide, to preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage). Nitrogen is used in particular applications:

  • The production of electronic parts such as transistors, diodes, and integrated circuits
  • Dried and pressurized, as a dielectric gas for high-voltage equipment
  • The manufacturing of stainless steel
  • Used in military aircraft fuel systems to reduce fire hazard, (see inerting system)
  • On top of liquid explosives as a safety measure
  • Filling automotive and aircraft tires[22] due to its inertness and lack of moisture or oxidative qualities, as opposed to air.
  • Used as a propellant for draft wine, and as an alternative to or together with carbon dioxide for other beverages.
  • Nitrogen is commonly used during sample preparation procedures for chemical analysis. It is used to concentrate and reduce the volume of liquid samples.
  • Nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns.

It is one of the most commonly used compressed gases for pneumatic (pressurized gas) systems in portable pressure tools. Carbon dioxide also finds use as an atmosphere for welding, although in the welding arc, it reacts to oxidize most metals. Use in the automotive industry is common. When used for MIG welding, CO2 use is sometimes referred to as MAG welding, for Metal Active Gas, as CO2 can react at these high temperatures. It tends to produce a hotter puddle than truly inert atmospheres, improving the flow characteristics. It is also used in many consumer products that require pressurized gas because it is nonflammable.

Shielding gases are inert or semi-inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding (GMAW and GTAW, more popularly known as MIG and TIG, respectively). Their purpose is to protect the weld area from atmospheric gases, such as oxygen, nitrogen, and water vapour.

Helium is used as a shielding gas in arc welding processes on materials that at welding temperatures are contaminated and weakened by air or nitrogen.[4] A number of inert shelding gases are used in gas tungsten arc welding, but helium is used instead of argon especially for welding materials that have higher heat conductivity, like aluminium or copper. Another Helium application involves cooling the superconducting magnets in medical MRI scanners.

H2 is used as a shielding gas in welding methods such as atomic hydrogen welding.[87][88] H2 is used as the rotor coolant in electrical generators at power stations, because it has the highest thermal conductivity of any gas. Liquid H2 is used in cryogenic research, including superconductivity studies.

In more recent applications, hydrogen is used pure or mixed with nitrogen (sometimes called forming gas) as a tracer gas for minute leak detection. Applications can be found in the automotive, chemical, power generation, aerospace, and telecommunications industries. Hydrogen is an authorized food additive (E 949) that allows food package leak testing among other anti-oxidizing properties.

Oxygen is used in medical applications, metal cutting and welding and in water treatment. Oxygen is used in oxyacetylene welding burning acetylene with O2 to produce a very hot flame. Oxygen is used in the industrial and chemical industries. Smelting of iron ore into steel requires large quantities of oxygen. Ethylene is reacted with O2 to create ethylene oxide, which, in turn, is converted into ethylene glycol; the primary feeder material used to manufacture a host of products, including antifreeze and polyester polymers.

North American industries using propane include glass makers, brick kilns, poultry farms and other industries that need portable heat. Propane is also instrumental in providing off-the-grid refrigeration, usually by means of a gas absorption refrigerator. Propane is also used as fuel for small engines, especially those used indoors or in areas with insufficient fresh air and ventilation to carry away the more toxic exhaust of an engine running on gasoline or diesel.
