A plasma cutter is used to cut any electrically conductive metal and it behaves like a high-temperature gas, but with a major difference and that is the fact it conducts electricity in order to cut through a metal. If you work with metals often or on a daily basis, you may know how important it is to have near you a good plasma cutter that provides accurate and clean cuts whenever and that matches your needs and accessories.

Plasma cutting units improved in time and now you can enjoy their productivity at a lower price, much quicker, they are portable, offering the chance to carry one of these units right there where you need, did not requires pre- heat and the arc cuts through a variety of metals, like ones with poor heat conductivity, like stainless steel, or ones with great heat conductivity, like aluminum. Being similar with a welding machine in some aspects, the capacity of plasma cutter is determined by its voltage and amperage. Though, unlike a welding machine, a plasma cutter requires low amperage levels and high voltage. Also, torch accessories and consumables may be different for several models of such machines. If you are a beginner you should take time to practice a little with such a tool, because the cut will reflect any hand movement and that can make either good or bad on the work surface. For those that never used a plasma cutter, or simply happens not to have very steady hands, there can use circle guides or roller guides for accuracy. Considering the functions a plasma cutter offers, we present you the best models that can handle any challenge and give a perfect result.
