What is Plasma Cutting?
Plasma cutting uses a plasma torch to direct a hot plasma arc. This arc cuts through metals like steel, stainless steel, aluminum, brass, and copper. The cutting process involves ionizing plasma gas to create a high-temperature jet.
An electric current flows from the torch through the gas and the metal, melting it quickly. Plasma cutters work efficiently in industries such as fabrication, automotive repair, and industrial construction.
They are valued for their speed, precision, and cost-effectiveness.
Plasma cutting provides a fast and exact way to shape metal, making it a favorite in many industries.
Next, let’s explore how plasma cutting works.
How Plasma Cutting Works
Understanding what plasma cutting is sets the stage for exploring how it operates. A plasma cutter creates an electrical channel of ionized gas from the cutter to the workpiece. This channel completes a circuit through a grounding clamp.
Compressed gas, such as oxygen or air, is blown through a nozzle at high speed. This forms an arc that cuts through the metal. Handheld torches can cut steel up to 38 mm (1.5 inches) thick.
Industrial CNC torches can handle materials up to 150 mm (6 inches) thick. The process starts with a high-voltage spark that ionizes the gas, turning it into plasma.
The plasma ejection melts the metal quickly and precisely. High-frequency current keeps the arc stable during cutting. CNC plasma cutters use numerical control to move the torch accurately.
This allows for detailed cuts on cutting tables. The intense heat from the plasma, reaching up to 30,000°F, melts the metal rapidly. Plasma cutting is efficient for thick metals and is widely used in metalworking and automobile repair shops.
The combination of high temperature and fast gas flow makes plasma arc cutting a powerful method for cutting tough materials.

Choosing the Right Plasma Cutter
With these pros and cons in mind, selecting the right plasma cutter is essential for your projects. Start by deciding between analog and inverter plasma cutters. Analog models need over 2 kilowatts and heavy transformers, making them less portable.
Inverter cutters are lighter and often use IGBTs, ideal for mobile tasks.
Consider your CNC cutting needs. There are three main configurations: 2-Dimensional, 3-Dimensional, and Tube and Section. Modern plasma cutters now cost under $300, making them accessible for various budgets.
Think about the thickness of metals you’ll cut and the plasma cutting process required. Choosing the right cutter ensures precision and efficiency in metal fabrication.
