Powder Solar Flux B 450g tin

Solar Flux is proprietary blended complex chemical compound in the form of a very fine powder. Application is simply mixed with alcohol (methanol/methyl alcohol preferred) and brushed on the weld joint. Formulated to shield the back of the weld joint from oxygen, dissipate heat and unwanted oxides and to clean the surface of the metal. Aids in the flow of filler metal over base metal to form a protective barrier to prevent re-oxidation and heat scale. Type B is best used for welding stainless steel (except 309, 310), precipitation hardening steels, chrome-moly steels, other alloy steels with nickel content below 25%. Can be used as a back purge flux to eliminate purging on small jobs. Welding activity range 2000°F - 2900°F (1093°C - 1593°C).
