Roll of .6mm solder 2% Flux 100 gram so a sizeable roll.
Here is some good old 2% flux cored solder. .6mm diameter so great for light work. I usually have 2mm diameter rolls as well.
With this stuff you just tin your iron with it and go. Save heaps of time and heaps of heat so helps in not overheating your plugs and wires.
Its not cheap because its the real deal.
