This is brilliant advive if you are fixing gutters or copper pipes in you house but you won't be doing your cells any favours with these "tools"
Use a good, high power soldering iron with a large tip and a quality solder and just have someone show you how to do it. Soldering cells is one of those things you really have to be shown...
