AWS F7AZ-EL8
Sintered Flux F7AZ-EL8
Sintered Flux,AWS F7AZ-EL8is 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.

Application
Sintered Flux, AWS F7AZ-EL8 can be 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.

Notes:
1. Flux must be baked at 300°C ~ 350°C for 2 hours
2. Impurities such as rust, oil stain and moist should be cleared before welding.
