Helium (He)

Helium (He) is a chemical element and a colorless, odorless, tasteless, inert gas. It has the smallest atomic radius of any element and the second-lowest atomic weight. It is lighter than air.
Most people know that helium is used as a lifting gas in blimps and party balloons, but they can't name another way in which it is used. The number one use of helium is as a cooling gas for magnetic resonance imaging (MRI) machines used in medical facilities. Other important uses of helium include: a protective gas for welding, an inert gas for controlled atmosphere manufacturing, a fugitive gas used for leak detection, and a low-viscosity gas for pressurized breathing mixtures.

Oxygen (O2)

Oxygen (O2)  is an active, colorless, odorless and tasteless. It  has numerous uses in steel making and other metals refining & fabrication processes, petroleum processing, glass/ceramic & pulp/paper manufacture. It is used for environmental protection in municipal and industrial effluent treatment plants and facilities. Oxygen (O2)   is widely used with fuel gases in gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening, and flame straightening. In gas cutting, the oxygen must be of high quality to ensure a high cutting speed and a clean cut

Argon (Ar) & Pure Argon (Par)

Argon (Ar)  is a monatomic, colorless, odorless, tasteless and nontoxic gas. It is valued for its total inertness in particular at high temperatures.  Argon is used in critical industrial processes such as the manufacturing of high quality stainless steels, plasma cutting and production of impurity-free silicon crystals for semi-conductor manufacture. Pure argon (Par) & argon (Ar)  mixed with various other gases, is used as a shield gas in TIG & MIG welding which employs a consumable wire feed electrode. The function of the shielding gas is to protect the electrode and the weld pool against the oxidizing effect of air. Pure argon is often used with aluminum.
