If you take the oscillographs of the arc current or voltage during the welding whith the automatic or hand welder, you will find the ripple in the arc voltage though the arc current is constant. Ripple occurs as such in the case of D. C. source, while it is superposed to the commercial frequency with A. C. source. Up to the present, the above phenomenon has been simply reduced to the spattering of the metal, the influence of the electric source, or the effect of the automatic welder. It seems, however, that there are problems which are inexplicable by the above explanations. For example, the period of the ripple is under 1/100sec., while the response time is as long as 17/100 sec. The Authors attribnted it to the self-regulation of the arc, and according to their theory, the spattering of the metal should be included in this self-regulation. Under the reasonable assumption, they have tried the mathematical analysis, and recognized that it satisfactorily coincides with the experimental results.
