Microwave transformer

These vary in power output and design, but can be readily salvaged and studied. Frequently used for DIY projects involving welders and high voltage, they provide a potentially lethal current. Its possible to re-wind the transformers secondary coil to produce different outputs of voltage. The core of the transformer is commonly composed of many thin slices of transformer steel which are shaped and then painted with insulating adhesive and stacked together to the desired height.
