Description + -

Metal-cored high efficiency wire for welding of carbon and C-Mn steels with tensile strength up to 510 MPa. Retains good mechanical properties at low temperature (down to -40°C). Efficiency is 20% higher than solid wire for the same welding parameters. Spatter free, good wetting even on poorly prepared materials and excellent bead appearance even at high welding speed. Minimum spatters makes INE M71TG ideal for multipass semi-automatic and automatic welding without the need for inter-run cleaning. To be used under gas shielding of Ar+CO2 mix.
