In the paper there is considered a process of electrode metal drops transfer at arc welding-surfacing with the emphasis of characteristic stages of their formation and motion in a molten bath for the realization of a welding method with the dosed electrode wire feeding. The analytical expressions are obtained defining terms of the existence of drop formation stages according to which it is possible to assess a level of inverse connections on arc process parameters introduced into a regulator of an electrical drive of the mechanism of electrode wire feeding. There are shown examples of carrying out a welding method with the dosed feeding the parameters of which are designed according to the procedure mentioned.
