### When was plasma cutting invented?
Plasma cutting was invented in the 1950s, specifically in 1956.
### What is plasma cutting?
Plasma cutting is a process used to cut through electrically conductive materials such as steel, aluminum, brass, and copper. It works by sending an electric arc through a gas that is passing through a constricted opening. This gas can be nitrogen, argon, oxygen, or a mix of gases. The electric arc ionizes the gas, creating plasma, which reaches temperatures of up to 30,000 degrees Fahrenheit. The high temperature plasma melts the material being cut, while the gas blows away the melted metal, resulting in a clean and precise cut.
### How does plasma cutting work?
Plasma cutting involves the use of a plasma torch, which is connected to a power supply. The power supply leads to the creation of an electrical arc within the torch, ionizing the gas and creating plasma. The plasma is then forced through a small nozzle at high speeds towards the material being cut. The high velocity of the plasma stream, along with the temperature of the plasma, allows the material to be melted and blown away, separating it into two distinct pieces.
### What are the advantages of plasma cutting?
1. **Versatility**: Plasma cutting can be used to cut a wide range of materials, making it a versatile cutting method.
.
2. **Speed**: Plasma cutting is quicker than traditional cutting methods, allowing for faster completion of projects.
.
3. **Precision**: Plasma cutting produces clean and precise cuts, making it suitable for intricate designs and detailed work.
.
4. **Portability**: Plasma cutting machines are compact and lightweight, making them easy to transport to different job sites.
### Are there any limitations to plasma cutting?
While plasma cutting offers numerous advantages, it also has some limitations:
1. **Thickness**: Plasma cutting is best suited for materials with a thickness of up to 1 inch. Thicker materials may require multiple passes, which can affect the quality of the cut.
2. **Edge quality**: While plasma cutting produces clean cuts, the edges may not be as smooth as those produced by other cutting methods such as laser cutting.
3. **Operating costs**: Plasma cutting systems can be expensive to operate, especially when compared to traditional cutting methods such as abrasive cutting.
