Do plasma cutters need an air compressor?

Yes, plasma cutters typically require an air compressor to function properly. The air compressor is used to provide the plasma gas that creates the high-temperature plasma arc that cuts through the metal being worked on.

The air compressor supplies the air that is then filtered and regulated to a specific pressure, which is required for optimal plasma cutting performance. Most plasma cutters require compressed air at a pressure of around 70-100 psi (pounds per square inch) and a flow rate of at least 4-5 cubic feet per minute (CFM).

It is important to choose an air compressor that can provide the necessary pressure and flow rate for the specific plasma cutter being used. Some plasma cutters come with built-in air compressors, while others require an external air compressor to be used.

In summary, plasma cutters require an air compressor to function properly. The air compressor supplies the plasma gas that creates the high-temperature plasma arc used to cut through metal. It is important to choose an air compressor that can provide the necessary pressure and flow rate for optimal plasma cutting performance.
