Formerly, we have reported the results of observation about the radiant phenomena of flash lamp or melting fuse with the impression of D. C voltage, which has been taken a photograph by the high speed (10^<-6>s) shutter due to the electro-optic effect of KDP z-cut crystal. Now, we observed the wave forms of terminal voltage and current pass through that fuse, and took a photograph of the radiant states of fuse in melting process for resistance load with the several supplied voltages of D. C 100,A. C 100 and 200 volt. In this case, we recorded the lagging time of the operation of high speed shutter from the impression of voltage by the memoryscope. As the result, we knew that the process of melting fuse shows the three modes in which solid fuse melts to liquid and vaporizes at finally according to the progress of time. At the beginning, a slight radiation lights at the terminals of the fuse holder and then glows to a big radiation and arc lighting, lastly burn out to the end.
