I have two rasters: the first is a basin with all pixels values equal to 0. The second raster (mask) has a single pixel with value = 1. In fact, I need only one raster where all the pixels into the basin must be = 0 and this specific pixel (in the mask) must have the value 1.
How can I do this process using ArcGIS Desktop?
I tried to use raster calculator with the sum "Raster 1 + Raster 2", but it did not work because the result is all the pixels into the basin equal to 1.

I provided a quick answer, assuming that the mask covers all null values in the basin raster, but does your mask layer need to exclude additional areas in the basin? I can update to reflect that.

Many thanks, SaultDon. The mask doesn't cover all the pixels in the basin raster. The mask is just a isolated pixel and I'm tryng to use this pixel to change the value in the corresponding pixel at the basin raster.

Convert the 0 values in mask to 1:
Con(1,0,"mask")
Then convert the null values in basin to whatever mask is.
Con(IsNull("basin"),"mask","basin")
I think you can put them together, haven't used ArcGIS raster calculator in a while but this is a possible one-liner:
Con(IsNull("basin"),Con(1,0,"mask"),"basin")
