Home Plasma Cutting Plasma Cutting Plasma cutting is a process used to very quickly and precisely cut steel and other metals of different thicknesses. Plasma Cutting uses an inert gas blown at high speeds. An electrical arc is then created through and around the gas, forming plasma. This plasma is hot enough to cut the metal. We can provide plasma cutting services through our network. To learn more about our metal bending services, call, email or visit one of our 7 locations in the UK.
