How to Select an Air Compressor for Your Plasma Cutter

Jan 5, 2023 | Plasma Cutting Tips

Whether you weld professionally or as a hobby, you will always need an air compressor for your plasma cutter. The air compressor increases air pressure, delivering it at a level high enough to create the spark that ignites the gas.

Unfortunately, the numerous air compressors available on today’s market have made choosing the right one more challenging. However, there are guidelines you can turn to when making your choice.

This post will show you how to select air compressors for plasma cutters, highlighting why Hypertherm’s plasma cutters would suit you.

Why Does Your Plasma Cutter Need an Air Compressor?

Your plasma cutter needs a high air pressure level to operate correctly. That is where air compressors come in.

An air compressor for plasma cutter is a device that pressurizes air and delivers it to your plasma cutter. Essentially, the compressor acts as a pressure regulator.

Choosing a Suitable Air Compressor

Here are some factors you should consider when selecting an appropriate compressor for your cutter.

Flow rate

A compressor’s flow rate refers to the amount of air it can deliver over a specific period. The flow rate determines how long a plasma cutter can operate before you’ll need to pause to allow the air compressor to cool down.

If you intend to use your cutter for long periods, you’ll need an air compressor with a higher flow rate.


Looking at the compressor’s power will help you determine airflow. Choosing an option with a high power rating would allow you to use your cutter for extended periods.

Duty Cycle

A compressor’s duty cycle refers to the amount of time your compressor can run before needing a break. It determines how often you’ll need to pause to allow the compressor to cool down.

The higher the duty cycle, the longer you can use your plasma cutter without stopping.

Size and Portability

When selecting an air compressor for your plasma cutter, it is also essential to look at its size and portability.

The compressor’s size determines how easy it will be to move around and store. For instance, if the air compressor is too heavy or large, transporting and storing it won’t be easy. Therefore, if you intend to take your plasma cutter to different job sites, opt for the smaller, more portable option.


Price should be the final consideration when weighing your options. Pick a compressor that falls within your budget and offers the features you deem essential.
