An HD Plasma Cutter, also known as a high-definition plasma cutter, is a type of cutting tool that uses a plasma arc to cut through various types of metal. It is an advanced version of a standard plasma cutter, offering higher precision and quality cuts. It's worth noting that technology advances rapidly, and new models or improvements may have been introduced since my last knowledge update in September 2021. So, it's always a good idea to research and consult with manufacturers or suppliers to get the most up-to-date information on HD plasma cutters available in the market.
