Argon – Argon Gas Bottle – MIG & TIG Argon Welding Gas Near Me – What is Argon?
What is Argon?
Argon gas is an inert gas, with the chemical symbol “Ar”.
It is a non-flammable gas and it is a noble gas that is almost completely non-reactive with all materials at all temperatures and pressures.
Argon is heavier than air so it could be a dangerous asphyxiant in an enclosed space.
It is used by welders as shielding gas to protect the weld, in incandescent light bulbs to stop oxidation of the filament and in double paned windows, for its superior acoustic and thermal properties.
Argon is typically used when a dry, inert atmosphere is required.
It is the third noble gas, making up about 1% of our atmosphere.
Argon is 2.5 times more soluble in water than nitrogen and is about as soluble as oxygen.
It is gaseous at STP and is a chemically inert element gas that is colourless and odourless.
Argon is the most frequently used inert gas.
TIG Argon Welding – MIG Welding
Argon is the primary TIG welding gas as a shielding gas for most metals.
Argon is also used for MIG welding aluminium and MIG brazing.
In general the term MIG (European term for Metal Inert Gas) welding is used loosely in our industry and covers everything Gas Metal Arc Welding (US term is GMAW) related.
The term MIG correctly refers only to the use of fully inert shielding gases such as argon and helium, and generally mixes of these two.
Pure CO2 and argon and CO2 mixtures are the most common active gases used for MIG welding gas, aside from MIG brazing and aluminium.
As soon as a CO2 or O2 component, or both, are introduced to the blend, it then becomes an active shielding gas.
This is because the active components of CO2 and O2 react with the molten weld pool and droplets moving across the arc, and is hence termed Metal Active Gas (MAG welding).
This is the difference difference between MIG and MAG welding.
Pure CO2 and argon and CO2 mixtures are used in the production of reactive elements, including titanium.
Argon gas is mostly used as TIG or GTAW welding gas, shielding gas and purging gas, supplied in argon gas bottle sizes.
Argon gas is the principal gas used in shielding gas applications due to its high density and total inertness.
The low ionising potential of argon allows easy forming of a welding arc without reacting with the metal components being welded.
Argon gas can be used on a wide range of ferrous and non-ferrous metals for welding and cutting.
It is the most affordable alternative, when nitrogen is not sufficiently inert.
Argon is also used as an insulating gas between the panes of dual pane windows, as it has low thermal conductivity, pumped in between with argon gas bottle pressure.
It is stored and transported in various argon gas bottle-cylinder sizes and larger vessels.
Laser Welding Machine – Laser Cutting Machine – Laser Cleaning Machine
100% Argon or Nitrogen are widely used for hand-held laser welding machine, laser cutting machine or laser cleaning machine systems.
The choice between the two gases is dependent on the advice of the equipment supplier and the material being processed.

Argon Uses – What is Argon Used For? Common Uses of Argon
Argon uses are varied. Common uses of Argon include as shielding gas in welding, the electronics industry, abattoirs, fire retardant, light globes and window insulation.
- Argon welding gas bottles for MIG and TIG welding processes and for plasma cutting
- Argon gas bottles for welding and cutting a wide range of ferrous and non-ferrous materials
- Argon welding gas bottles are used in arc welding such as gas metal arc welding and gas tungsten arc welding, as a shielding gas.
It is used in dual paned windows for thermal insulation, pumped in between the panes with argon gas bottle pressure, providing more energy efficient windows.- In the electronics industry, argon is used for growing crystals of silicon and germanium in a controlled atmosphere.
- It is used in the poultry industry to asphyxiate birds, as it is more humane than other abattoir options.
- It is used for extinguishing fires in special instances where product or equipment might be damaged by foam, water or other extinguishing agents.
- Argon is used inside incandescent light bulbs/globes. Argon It preserves the filaments from oxidation at high temperature, by displacing oxygen.

TIG Welding with Argon Welding Gas Near Me
Argon welding gas is also used in TIG welding. TIG welding gas is typically a mixture of argon with helium, hydrogen and/or nitrogen added for better welding speeds and process stability.
TIG is an acronym for “Tungsten Inert Gas”. TIG welding gas is also used with gas tungsten arc welding (GTAW), using a tungsten electrode and argon shielding gas.
TIG welding gases are inert gases used as shielding gases in the TIG welding process. Argon shielding gas protects the weld pool from nitrogen absorption and oxidation during TIG welding. You get improved weld quality and less rework time.
Who Discovered Argon?
1785 – Argon was hypothesised as a component of air by Henry Cavendish.
1882 – New lines in the colour spectrum indicated a new unknown gas within air, based on research by H. F. Newall and W. N. Hartley.
1894 – Lord Rayleigh and Sir William Ramsay first isolated Argon from air. To achieve this, they removed the oxygen, carbon dioxide, water, and nitrogen from clean air and deduced Argon from what remained.
How is Argon Made?
- Argon is produced using fractional distillation.
- It is cryogenically separated from the air in a distillation tower.
- The entire installation is known as an Air Separation Unit – ASU.
- It is then stored as a liquid, in argon gas bottles, for ease and economical transportation.
