JQ.SJ402 is a kind of Silicon manganese acid sintered flux, the alkalinity is about3.2, it is a circular particles and the size is 2.0 ~ 0.28mm (10 ~ 60 mesh). With excellent welding technological properties, stable arc, slag detachability, beautiful appearance; the flux is insensitive of rust, oil and oxide film on the work piece when welding. AC and DC both are applied. Connect the wire to positive end while using DC.

Working with H08MnA welding wires can be used for welding low carbon steel and some low alloy of thin steel plate and medium steel plate. It is used for welding metal structure of locomotive and mining machinery, especially suitable for high-speed welding on thin plate.
