A solid wire for gas shielded arc welding having excellent rusting resistance and feedability by adhering a homogeneous liquid phase-surface treating agent onto a welding wire within a specific range is provided, wherein the homogeneous liquid phase-surface treating agent is prepared by containing metal salts and nonmetal phosphorous with superior anti-corrosive and lubricating properties in a hydrocarbon compound. A solid wire for gas shielded arc welding is obtained by adhering or oiling a surface treatment oil containing metal salts comprising sodium(Na), potassium(K), calcium(Ca) and zinc(Zn), 0.10 to 0.80 wt.% of nonmetal phosphorous(P), and 97.10 to 99.78 wt.% of a hydrocarbon compound having two functional groups selected from an easter group, a carboxylic acid group and an alkane group onto an iron wire for welding used in gas shielded arc welding in an amount of 0.03 to 0.60 g per 1 kg of the welding wire, wherein the metal salts comprise 0.05 to 0.85 wt.% of Na+Ca, 0.05 to 0.70 wt.% of K and 0.02 to 0.55 wt.% of Zn based on the total weight of the surface treatment oil.
