For all those who take it very seriously.
Technical gases
Whether you are a DIY enthusiast or a professional: precise work steps such as flame cutting, welding or calibration require technical gases, also known as industrial gases, which differ from conventional gases due to their particularly high gas quality. We offer you a wide selection of these.
Overview
Why technical gases are so special
Technical gases are distinguished from natural gases by their specially tested degree of purity. In addition to air gases such as argon, oxygen, nitrogen or carbon dioxide, gases obtained by chemical processes such as acetylene also play an important role, particularly in industry, thanks to their useful properties for various areas of work.
Whether acetylene for flame cutting or argon for calibration: As a self-collector or delivery customer, you can obtain selected technical gases from us in exchange and rental cylinders with filling quantities of ten to 50 liters.
We are here for you!
Technical gases are diverse and complex. We will be happy to help you find the right solution for your application.

Acetylene
Guarantees optimum cutting speed and smooth edges when flame cutting. In combination with oxygen, acetylene achieves a flame output of over 3000 °C, which is why it is particularly suitable for metallic materials with high heat dissipation such as steel, copper and aluminum.
Argon
Belongs to the noble gases and is used as a shielding gas for metal inert gas welding (MIG) and tungsten inert gas welding (TIG), preferably for non-ferrous metals (such as aluminum and its alloys) and for high-alloy steels (such as stainless steel). Argon is also a main component of most welding gas mixtures.
Carbon dioxide (CO2)
As a technical gas, carbon dioxide (CO2) is particularly suitable as a shielding gas for gas metal arc welding (GMAW) of light-alloyed structural steels and thin to medium-thick sheet metal. CO2 is used either in its pure form or in a shielding gas mixture of 18% CO2 and 82% argon.
Oxygen (O2)
By adding pure oxygen, higher temperatures can be achieved in welding and firing technology. This is why O2 is often used as an ideal supplement to acetylene as a fuel gas. Oxygen is also suitable for removing impurities, which oxidize and are separated.
Nitrogen (N2)
Nitrogen is used in shielding gas welding as it is not very reactive and can smother flames. Nitrogen protects the melting wire and the molten metal from the oxygen contained in the air.
