diamondspark 700 RC is a flux-cored wire with a rutile core. It suits welding quenched and tempered high-strength steels and is used in machine building, crane structures and commercial vehicles.
It is used on grades such as S620Q, S620QL, S690Q, S690QL, S620QL1, S690QL1 and ASTM A 514. The seamless sheath keeps moisture away from the core even after longer storage, and all welding positions are open to it, which helps on site.

Do not exceed the permitted interpass temperature, an overheated heat affected zone loses its toughness. Hold the torch tilted slightly backwards so the slag flows behind the pool. Remove the slag before every following bead, slag left between layers is the most common source of inclusions. Thinner diameters suit root runs and thin sheet, thicker ones the fill passes.
