The coating of this electrode is essentially composed of a mineral called rutile. The latter is made up of 95% titanium dioxide, a very stable compound that guarantees excellent arc stability and high fluidity of the bath, with an appreciable aesthetic effect on the weld. The task of the rutile coating is however that of guaranteeing a smooth, easy-to-make melt, facilitating the formation of an abundant and viscous slag that allows good smoothness in welding, especially in a flat position. In this case the cord is visually beautiful and regular.
