PURPOSE:To reduce the generating amount of spatters and to obtain a wire excellent in welding operability in a high amount of deposition, by filling the specific amount of a flux, containing the specific amounts of specific components in a steel skin, and specifying the carbon content in throughout wire. CONSTITUTION:A flux containing, by weight percent, 60-85% iron powder, 8-25% deoxidizing agent, 1-10% arc stabilizing agent and 0.1-6% inorganic fluoride is filled by the amount of 15-35% with respect to the total weight of a wire in a steel skin, and the carbon content throughout the wire is limited to <=0.05% to form a large-diam. flux-cored wire.
