While it might seem fictional, plasma is actually a common and widespread method of cutting certain materials. But, unlike some of the aforementioned cutting methods, the “certain materials” that can be cut using plasma must be electrically conductive — such as steel, aluminium, brass, and copper.
Plasma cutting systems use an accelerated jet of extremely hot, electrically ionized gas (plasma) to form an electric channel from the cutting head through the workpiece, and then back to the cutting head. These fabrication machines can be found in a number of different operations because they are fast, precise with their cuts, and are relatively inexpensive to operate.
Companies that benefit the most from this particular cutting process tend to vary from large industrial manufacturers that need to make the same cut hundreds of times to small hobbyist shops that create metal art from recycled pieces.
