In general, the uncompressed gas (at atmospheric pressure) in an electric arc is partially ionized. The temperature of the such so-called free-burning electric arc is ranging from 6,000℃ to 8,000℃.
When imposed to high pressure, the free-burning electric arc will ionize almost all the gas within it, thereby creating a plasma jet with high velocity, high current density, and a small conductive cross-sectional area. The plasma jet will immediately reach a temperature ranging from 15,000℃ to 30,000℃, quickly melting down the metal processed.
With our plasma cutter, the cutting process involves utilizing an extremely sharp and high-temperature plasma arc to quickly pierce through the workpiece and then blow away the molten material.
Plasma cutters are tools used for cutting various types of metals, including steel, aluminum, and copper. They operate by creating a high-velocity jet of ionized gas called plasma. This superheated plasma, often reaching temperatures of over 30,000 degrees Fahrenheit (16,649 degrees Celsius), melts through the metal being cut. Here's a brief explanation of how plasma cutters work:
1. Gas Supply: The process begins with a supply of inert gas, typically compressed air, but sometimes other gases like nitrogen or argon are used depending on the specific application. This gas flows through the plasma cutter's nozzle.
2. Electric Arc: Inside the plasma cutter, an electric arc is created by passing an electric current through a small opening in the nozzle. This arc ionizes the gas, turning it into a high-temperature plasma.
3. Plasma Formation: The intense heat of the electric arc causes the gas molecules to break apart, forming a plasma consisting of positively charged ions and free electrons. This plasma is extremely hot and can reach temperatures much higher than those of a typical oxyfuel flame used in traditional cutting methods.
4. Focused Jet: The plasma is then forced through a narrow, constricted nozzle, which accelerates the plasma and focuses it into a high-velocity jet. This focused jet of plasma is what actually does the cutting.
5. Metal Melting: When the plasma contacts the metal being cut, it rapidly heats the metal to its melting point. Simultaneously, a high-velocity gas stream blows away the molten metal, creating a clean and precise cut.
6. Controlled Movement: Plasma cutters are often mounted on CNC (Computer Numerical Control) systems that precisely control the movement of the cutter's nozzle. This allows for intricate and precise cutting patterns, making it suitable for various applications.
Plasma Cutters Welding Equipment, play a crucial role in the welding process by enabling precise and efficient metal cutting. When working on welding projects that involve joining metal components, it's often necessary to prepare the edges of the metal pieces for welding. This preparation typically involves cutting the metal to the desired shape and size, and this is where plasma cutters shine.
By providing a clean, high-temperature cut, plasma cutters ensure that the edges of the metal pieces are smooth and free from contamination. This cleanliness is essential for achieving strong and durable welds. Additionally, plasma cutters offer speed and accuracy, allowing welders to complete their projects more efficiently. The combination of welding equipment like plasma cutters and welding machines empowers welders to achieve precise cuts and high-quality welds, making them indispensable tools in the welding process.
