Gas with multiple uses in the metal fabrication sector
It can be used as pure or mixed fuel gas, it is widely applied in welding processes mixed in small percentages to Argon as protection gas for the TIG / MIG process of austenitic and copper steels or in MAG welding of austenitic steels.
It also finds application in gas mixtures intended for root protection, but it is not compatible in processes with materials such as carbon steel and aluminum.
Also used in plasma welding (always mixed) for the generation of the plasma itself, but also in the plasma cutting process in considerable percentages for cutting austenitic and high-alloy steels for high thicknesses.

Acetylene for Metalfabrication Industry
Acetylene is the synthetic fuel gas which, combined with oxygen, generates a flame at very high temperature and is the most commonly used fuel gas in braze-welding and oxy-fuel technologies. Its particular instability is resolved by storing it in special cylinders that contain a porous mass which is first saturated with a solvent that Can be Acetone or DMF (Dimethyl Formalamide) which serve to dissolve the Acetylene making it so stable and safe both during transport and in phases of use.
