    Varigon H6

    Higher penetration quality and welding speed mainly by materials with medium and higher thickness and for mechanized WIG and plasma welding.

    VARIGON® H (< 2.9 % H2) is applied for WIG welding of austenitic steels that contain 2 % of ferrite at the maximum (e.g. 1.4435 % or 1.4439 %) and of nickel alloys. Compared to argon, it improves the penetration, enhances the welding speed, and reduces the porousness. The mixtures that contain hydrogen offer, thanks to their reductive impact, an additional protection: oxygen residuals combine with hydrogen parts and the oxide creation (colouring) is therefore prevented. It may be used for the weld root protection or forming.
