The inert gas par excellence
Noble gas, 1.38 times heavier than air, has a low ionization potential, so it can facilitate the formation of an electric arc. Argon has a tendency to concentrate penetration of the weld bead into the base material. It also offers a good influence on the stabilization of the electric arc.

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.

Hydrogen for Metalfabrication Industry
Combustible and very light gas, it has the characteristic of binding easily with oxygen to form water; it is an exothermic reaction, but it has the characteristic of deoxidizing everything it encounters if supported by a little energy. In the TIG and MAG welding processes it is used in small percentages precisely for its deoxidizing function but also for the contribution of energy that it can give to the welding process.
