The solder would not have come from a blown fuse. I think that the OEM fuse elements are tinned cupronickel. Someone has done some work in there. If you can scrape the solder until it is clean and shiny, try a new fuse. Should work. The compressor should cycle anyway. If it does so quickly, shut off A/C and wait a while before trying again. If it engages and the cycles off, you have another problem as well. Perhaps excessive refrigerant pressure, or belt slippage or bad speed sensor..
