In assembling these kits, we took our inspiration from Joe Silvera's book, "Soldering Made Simple" (now out-of-print). The book "Soldering Jewelry" is now included with both of these kits. They include all the essentials for soldering with inexpensive, easy-to-use micro torches. There are 2 versions of this soldering kit; the first version includes a simple, hand-held butane torch and the other version substitutes for this torch the EZ Torch, used with disposable propane tanks and room air.
