                                              Features and Applications    
                                              SJF-711 is flux cored wire of gas shielding arc welding for welding of mild steel and 490MPa high tensile steels. It has deep Penetration use in DC(+), It can be used for the Situation of high impact ductility requirement, It has good weldability, few fume, mellow and stable dldctric arc, whole slag cover and easily to clean, X-ray check well. It is suitable for welding in shipbuilding, ocean drilling platform, storage tank, steel structure, boiler, Pressure Vessel, steel pipeline and heavy machinery.

                                              Points for Attention    
                                              ¡¤keep the shielding gas flow at 20-25/min.
                                              ¡¤Ensure the purity of shielding gas of CO2 must be above 99.98%.
                                              ¡¤Rid the welded part of rusty layer, damp, oil stain and dust, etc.
                                              ¡¤Always keep torch nozzle clean and TIP in good condition.
                                              ¡¤Ensure each weld pass temperature below 150¡æ for multi-run welding.
