DESCRIPTION
Tubular rutile flux-cored wire for single or multipass welding of carbon, carbon-manganese steels and similar grades of steels, including fine grain ones, with CO2 or 80% Ar + 20% CO2 mix shielding gas. The good weld ability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag. Deposited weld metal gives excellent impact properties down to -40°C.
