 note = {application/pdf, Several experiments concerning the maximum arc length were carried out as the basic research for the stability of the electric arc in welding. In this paper we describe an experimental study of the variation of the maximum arc length under windy conditions. A summary of the results is shown below. (1) Under the windless conditions the maximum arc length, while the angle of electrode is not changed, increases nearly in proportion to the electric current. As the wind velocity increases the maximum arc length decreases as a whole and the whole value evidently tends to be constant independently of the current. (2) When the angle of electrode is changed under the windless condition the maximum arc length comes to be the largest at 90°angle of electrode, but in the wind velocity of 4 m/sec or 9 m/sec it comes to be the largest at about 45°angle There is not very great change in the value of L_(θ)/L_(π/2), where  L_(θ) means the maximun arc length at θ°and L_(π/2) means the maximum arc length at 90°angle of electrode, independently of the current and the angle is only relevant to the value under both of the previous atmospheric conditions. (4) In the constant current the arc angle is dependent on the angle of electrode and as the wind velocity increases it is not affected very much at 45°angle of electrode, but beyond 45°angle the tendency is recognizably clear that the arc angle increases in addition to the wind velocity.},
