How does a plasma cutting machine work?

Plasma cutters use compressed air or other gases, such as nitrogen. Ionisation of these gases takes place to create plasma. Typically, the compressed gases come into contact with the electrode and then ionise to create more pressure. When the pressure builds up, a stream of plasma is pushed towards the cutting head.

Do you need an air compressor for a plasma cutter?

Plasma cutters need air pressure to cut in a two-stage process. Therefore, all plasma cutters need an air compressor to generate enough air pressure for the task. If you buy a plasma cutter without a built-in source of air, you’ll need a separate air compressor.

How hard is it to use a plasma cutter?

The idea behind a plasma cutter is to cut tough-to-manipulate metal using very high temperatures that turn gas into plasma. Even though there are a lot of intense reactions and very high temperatures forming inside a plasma cutter, the user’s part is relatively easy.

What are the disadvantages of plasma cutting?

Disadvantages

• Most plasma cutters aren’t useful for thicker or denser metals.
• While it limits ambient heat, plasma cutting is noisy and generates excess fumes.
• Plasma is also infamous for creating very bright flashes while the cutting is ongoing.

What gas does a plasma cutter use?

Argon gas is used when plasma marking (a whole other subject). A mixture of Argon and Hydrogen is often used when cutting thicker Stainless Steel or Aluminum.

Can a plasma cutter Weld?

With the right torch design, a nitrogen-water injection, less expensive than other gases, can work well when plasma cutting aluminum and stainless material for subsequent welding. The process involves an electrode surrounded by nitrogen, which is heated by an electric arc to form the plasma.
