A good plasma cutter will make cutting through sheet metal a breeze, allowing for clean lines, focused cutting and a terrific end result. Plasma cutters require the use of some safety equipment, such as eye protection, gloves and making sure exposed skin is covered adequately. The cutter uses a high-velocity jet of ionized gas , pushed through a smaller plate to provide pressure. The gas conducts electricity, which then melts the metal, cutting it cleanly and sharply. Plasma cutters are available at different voltages and are portable. There are many different sizes of tips and drag shields, for variety in cuts. Some of these cutters have multi-volt plugs, allowing quick connection with a power source, contributing to the flexibility of use. A plasma cutter on the job site or farm can be an asset when building, manipulating metal or repairing already installed work. This is a tool which requires little maintenance.
