Types of Plasma Cutters

Plasma cutting technology has evolved, offering various types tailored to diverse cutting needs. The two primary categories are Conventional Plasma Cutters and High-Definition Plasma Cutters. Each type has distinct features and applications, making them suited for specific tasks in metal fabrication.

Conventional Plasma Cutters

Conventional Plasma Cutters are known for their versatility and are widely used in many fabrication shops. These cutters use a high voltage electrical arc and a compressed gas, such as air, to cut through metal. They are particularly effective for cutting thicker metal plates and are valued for their speed and efficiency. Despite their lower initial cost, conventional plasma cutters can sometimes leave behind a rougher edge finish, which might require additional finishing work.

High-Definition Plasma Cutters

High-Definition Plasma Cutters, on the other hand, represent a more advanced technology. They are designed for precision, producing a much finer and higher quality cut compared to conventional plasma cutters. These cutters utilize a tightly focused arc and often include computer controls to ensure precision and consistency. Ideal for detailed and intricate work, high-definition plasma cutters are commonly used in industries where precision is paramount, such as automotive and aerospace manufacturing.

 

 

How Plasma Cutting Works

Plasma cutting is a sophisticated process that combines electrical and gas technologies to cut through various materials. Understanding how the plasma arc forms and the role of gases in this process is key to appreciating the efficiency and versatility of plasma cutting machines.

The Plasma Arc Formation

The plasma arc forms when an electric current passes through a gas that is blown through a narrow opening. This process begins with the gas (often air, nitrogen, or oxygen) being subjected to extremely high temperatures, causing it to ionize and become a conductive plasma. This plasma, driven by the electrical current from the cutter’s power supply, forms an intense, focused arc that is capable of melting metal at the point of contact. The intense heat of the plasma arc, reaching up to 40,000 degrees Fahrenheit, easily slices through metal, allowing for precise and efficient cutting.

Role of Gases in Plasma Cutting

Gases play a crucial role in the plasma cutting process. The choice of gas affects the quality of the cut, the speed of cutting, and the thickness of the metal that can be cut. For instance, using air as the plasma gas is cost-effective and suitable for cutting steel, stainless steel, and aluminum. Nitrogen, on the other hand, is used for higher current levels and provides excellent cut quality, especially on stainless steel and aluminum. For the most precise and high-quality cuts, a combination of gases, such as hydrogen and nitrogen, can be used, especially in high-definition plasma cutting systems.
