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).

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.

We offer argon:

  • 10 l (2,14 m³, 200 bar);
  • 20 l (4,34 m³, 200 bar);
  • 50 l (10,7 m3, 200 bar);
  • Cylinder bundles 12 x 50 l (128,4 m3, 200 bar);
  • Cylinder bundles 12 x 50 l (183,6 m3, 300 bar);
  • Euro-cylinders from 230 till 1000 l.
  • Liquid argon (tons).

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.

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

Argon is used to purify metals and to protect liquid metal from contact with the surrounding atmosphere and interactions.

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 harm to the human body, but this gas has the property of expelling oxygen from the air. In the air at more than 33 percent. concentration of these gases, there is a risk of suffocation and the use rooms must be ventilated.
