Flux filling wire has a specific surface area of 0.005 to 0.035 defined by the following formula when the apparent surface area is Sm and the actual surface area is Sa in the measurement area of the surface thereof, and the surface is 0.004 to 0.24 g / m 2. Molybdenum sulfide is attached.n n n Specific Surface Area = (Sa / Sm) -1n n n In addition, the solid wire has a specific surface area of 0.0005 to 0.05 and molybdenum sulfide having 0.001 to 0.5 g / m 2 attached to the surface. Thereby, arc welding wire which can satisfy | fill enough the characteristics, such as a wire supply property, the electricity-carrying stability between a tip wire, and a rust resistance, is obtained. |
