Argon (Ar) is non-toxic, odourless and colourless high-density inert gas used as protection gas in welding various metals.

When using argon gas during welding process, smelted metal is denser and, as a result, the metals are welded faster. Argon is characterised by extremely low thermal conductivity, therefore, is also used in other fields of industry.

Argon is obtained from the atmosphere by dispersing the air. Argon gas is filled in grey coloured cylinders with dark green shoulder, Euro-cylinders and other cryogenic containers.  Argon used for welding meets LST EN ISO 14175 standard (Group I1).

We offer to purchase argon in:

5 l cylinders (1.1 m3, 200 bar);

10 l cylinders (2.14 m3, 200 bar);

20 l cylinders (4.34 m3, 200 bar);

50 l cylinders (10.7 m3, 200 bar);

Cylinder bundles 12 x 50 1 (128.4 m3, 200 bar);

Euro-cylinders from 230 l to 1,000 l.

We can fill the cylinders of other volumes as well. The clients buying a considerable amount of argon are supplied with special storage tanks for the product and argon is delivered with semitrailers.

Fields of industry


Argon protects materials from oxidation when welding, smelting, cutting metals and their alloys: aluminium, aluminium and magnesium alloys, stainless, heat-resistant chromium and nickel alloys and different types of treated steel. Argon is also used as protective gas when welding ordinary steel and aluminium. Argon gas is used for TIG, MIG and plasma welding processes and protection of welding root and also facilitates the ignition of the arc.

Production of glass

For larger effectiveness of thermal and sound insulation, double and triple glass packages are filled with argon.


Argon is used for purifying metals, protection of liquid metal from contact with environment and their interaction.


Pure argon is used as inert gas that protects semi-conductors from impurities (e.g. argon creates the environment for the growth of silicon crystals and germanium).

Vehicles and transport

Compressed argon is used for filling vehicle airbags.

Production of lamps

Argon is used to fill filament, luminescence and neon lamps of advertising signs (argon has a feature of glowing in blue).


Argon does not cause direct damage to human organism; however, this gas has a property to push oxygen out of the air. If the concentration of this gas exceeds 33%, there is a risk of suffocation, therefore, production premises should be ventilated. More information on safe handling of argon is available in the provided material safety data sheet.
