SC – 70A is a metalcored flux cored wire for welding in protective atmosphere with gas mix is 80 % Ar + 20 % CO2.The use of this wire allows to combine the high efficiency of deposition of a cored wire with the efficiency of a solid wire .SC- 70A has excellent arc stability , not only at high parameters , but also at low current (up to 50Amp ) .Particularly suitable for multipass welding and automatic welding at high speed.Excellent impact values at low temperatures and low values of diffusible hydrogen mixtures with 80 % Ar + 20 % CO2
It can be used for welding steels with medium and high tensile strength .Typical applications are in shipbuilding , bridges , heavy metalworking
