heat Why does only the tip of the electrode melt when

I think that the workpiece doesn't melt because it is usually a lot bigger than the electrode, therefore, it can dissipate the heat a lot faster. The electrode is thinner though, and I don't understand why the whole electrode doesn't melt if the current that flows through it is high enough to melt the tip of the electrode.
