Abstract

In our previous paper, (1) it was reported that the intense radio noise was generated bythe arc welding machine with high frequency. A further study on the radio noise caused by such a welding machine has been carried out, the results of which are presented here. The summary is as follows.
The radio noise caused by the arc welding machine with high frequency is mainly produced by parts of the lead wires connecting to a holder and a work, and in the case without such lead wires, the noise is comparatively small, i. e., the interfering radiation is very weak and the interfering voltage of the distribution line is comparatively small and is considerably reduced by the use of a group of condensers.
Therefore, it may be advisable for the purpose of noise reduction to shield such lead wires.
