Plasma Cutting Machine - A Cutting Machine With High-Temperature

A plasma cutting machine is a metal or plate-cutting technology that utilizes the high thermal energy of plasma heated to temperatures above 20,000°C. Plasma cutting is a thermal cutting technique that uses heat to cut metal. Before discussing this further, some of us may not know what plasma is. Basically, plasma is the fourth state of matter, alongside solid, liquid, and gas. By heating it intensively, gas can be transformed into plasma, which is why plasma is often referred to as ionized gas. It is important to remember that plasma cutting machines can only be used on metallic materials, such as copper, aluminum, steel, and other metals.

The Working System of Plasma Cutting Machine

The plasma cutting process begins by connecting the machine to a sufficient power source. After the machine is connected to electricity, gas will flow through the nozzle first. This gas serves as a medium to generate plasma that is subjected to high electrical currents. Once the high electrical current successfully passes through the plasma nozzle, a very strong electric arc is created, which is directed through nitrogen or argon gas, causing the gas to ionize and creating high-temperature plasma. The high temperature generated from this plasma can quickly and accurately cut metal. However, the cutting results may be inaccurate if the nozzle is not replaced and is forced to be used. The torch plasma, gas, and metal here are the main components of a plasma cutting machine. It is important to note that not all plasma cutting machine systems operate similarly. However, there are several types of cutting processes.

Types of Plasma Cutting Processes

• Conventional Plasma Cutting

• CNC (Computer Numerical Control) Plasma Cutting

• Air Plasma Cutting

• Pilot Arc

• Dual Gas Arc Plasma Cutting

Gas Used

Although the gases used for plasma cutting can vary, they generally include gases such as argon, nitrogen, and hydrogen. When these gases are ionized, a high-energy plasma is formed, ready to cut metal with precision.

1. Argon

The argon plasma arc is stable due to its properties as an inert gas. It is said to be stable since this gas hardly reacts with any metals at high temperatures. Because of the low plasma arc, argon gas has limitations when cutting.

2. Nitrogen

Nitrogen helps us achieve precise cuts and minimal oxidation. The inert properties and cooling effect of nitrogen make it a very effective protective gas. In addition, nitrogen gas has functions such as preventing overheating, producing more precise cuts, and helping to stabilize the plasma arc. Nitrogen gas is very suitable for cutting aluminum, stainless steel, and non-ferrous metals like copper.

3. Hydrogen

The combination of Hydrogen and Argon is the most common gas mixture and produces one of the strongest plasma cutting gases. The arc voltage, enthalpy, and cutting ability of the argon plasma jet are significantly enhanced by the mixture of hydrogen and argon. When the water jet is pressurized, the cutting capability of this combination also increases.

Benefits of using a plasma cutting machine

The advantages of using a plasma cutting machine include:

• Fast and efficient cutting

• Ability to produce complex design cuts with a high level of accuracy

• Wide range of applications

• Low operational costs

• Can cut various types of metals and shapes

Conclusion

A plasma cutting machine is a device that uses extremely high heat from ionized gas to cut metal. This process requires heating the gas to temperatures exceeding 20,000°C, allowing the machine to cut various types of metals. Simply put, this machine "burns" through the metal until it is cut. However, it is important to remember that this technology can only be used on metallic materials. In addition, it is also important for us to choose the right type of gas based on the type of metal that will be cut. By understanding the various types of plasma gases, we can choose the process that best suits our needs. Plasma cutting machines offer the best solution for various types of metals with precise cutting capabilities. PT.
