35 Facts About Plasma Cutter

What is a Plasma Cutter?

A plasma cutter is a tool that uses a high-velocity jet of ionized gas to cut through electrically conductive materials. These tools are widely used in various industries for their precision and efficiency.

1. Plasma cutters can slice through materials like steel, stainless steel, aluminum, brass, and copper.

2. The technology behind plasma cutting was developed during World War II for cutting and welding aircraft parts.

3. Plasma cutters work by creating an electrical channel of superheated, electrically ionized gas—plasma—from the cutter through the workpiece.

How Does a Plasma Cutter Work?

Understanding the working mechanism of a plasma cutter can help appreciate its efficiency and precision.

4. A plasma cutter uses an electrical arc to ionize gas, turning it into plasma.

5. The plasma reaches temperatures of up to 45,000 degrees Fahrenheit, making it capable of melting metal instantly.

6. Compressed air or inert gases like argon are used to blow the molten metal away, creating a clean cut.

Types of Plasma Cutters

Different types of plasma cutters are available, each suited for specific tasks and materials.
