It is naturally of great importance that a good electrode should be used in order to obtain satisfactory results in electric arc welding. For functionating the electrode to a full scope, its manipulation must be altered in accordance with its characteristics, whilst the welding operation must be done with such arc current as to be the most suitable for the properties and diameter of the electrode, the thickness of the base metal, etc. In practice, however, the selection of welding current which is adapted for the welding condition is often neglected, and in many cases is left to the discretion of the operators. The author has found, in his course of study on the deposit of the electrode, the fact that even under the same welding conditions the number of instantaneous short-circuits of arc varies according to the amount of arc current. Starting from this fact, he has made it clear by experiments that the best welding effects are made by the amount of arc current which causes the maximum number of instantaneous short-circuits. In the present paper, the author proposes a simple method as obtained from these results of determining the value of arc current which may become a standard in actual welding, when the arc voltage, the diameter of the electrode and the thickness of the base metal are taken into consideration.
