I have two rasters with the same extent, projected coordinate system, cell size and they are aligned.

"raster1" has continuous values ranging from 0 to 6.09 "raster2" has continuous values from 0 to 91.25

What I need to do is creating a new raster in which, cells that have "value=0", based on "raster1", they will remain 0 but in any other case, cells will be assigned a value based on the sum of the values from "raster1" & "raster2".

The expression I use in Raster Calculator is :

Con(("raster1" == 0), 0, (Con(("raster1" > 0) & ("raster2"  >= 0)), ...?

Obviously, this is not complete. What should I change?

Reset to default

This should do the trick: 

Con("raster1" == 0,0, ("raster1" + "raster2"))
