PlasmaCutters
1. Modern industry depends on the manipulation of heavy metal and alloys. We need metals to build the tools and transportation necessary for day-to-day business. The reason is simple: metals are extremely strong and durable, so they’re the logical choice for most things that need to be especially big, especially sturdy, or both.
2. The funny thing is that metal’s strength is also a weakness: because metal is so good at resisting damage, it’s very difficult to manipulate and form into specialized pieces. People can precisely cut and manipulate the metals using the plasma cutter. The plasma cutter is actually a common tool that has been around since World War II.
3. Plasma cutters are not the only devices to harness the power of plasma. Neon signs, fluorescent lighting and plasma displays, just to name a few, all rely on it to get the job done. These devices use "cool" plasma. Though cool plasma cannot be used to cut metals, it has tons of other useful applications.
