Firepower 1423-1112 Rosin Flux Core 40/60 Solder is used for electrical applications. It is completely non-corrosive and electrically non-conductive. 3/32-inch x 1/4-pound.
Great for heavy gauge electrical connections!
Works perfect for 1 gauge terminals and cables. Must use a torch. Don’t think you are gonna melt this with a puny soldering iron, it’s not gonna melt. You will complain that it doesn’t work when you just don’t know how to use it lol!
Works like it is supposed too.

works great for heavy gauge soldering
Just received 2 lbs for doing heavy electrical connections, works awesome this is 1/8″ a light torch is needed a puny 60W iron would barely melt because of the thickness. 1/0 200 amp connectors came out bright and shiny much easier to use for heavy jobs than making a rope of fine solder.
