The best air compressor for a plasma cutter is often determined by the amount of power it has and the size and type of tank. It’s important to have enough power so that your compressor can maintain a consistent flow rate.
For plasma cutting you need air compressor which has at least 2 – 4 horse power, 90 – 120 psi and a big 6 – 30 gallon tank. The larger the air compressor tank, the less time you’ll need to wait between cuts. So if you are cutting large pieces of metal continuously, then be sure to get one with a bigger capacity.
You can’t expect to do any cutting projects without an powerful air compressor on hand, so it’s important to know which one is the best for your needs.
To help you out, we’ve compiled a list of most popular models currently on the market that will suit any budget and work with all types of machines.

Buying Guide for Best air compressor for plasma cutter
Plasma cutters are a great way to cut through stainless steel, brass, steel, and aluminum.
You can cut through metals quickly and precisely as the metal gets burned through with a plasma cutter. An air compressor is needed to operate this device, and it needs to be used with care.
Plasma cutters require compressed air to create the plasma; either a built-in air compressor or an external supply of compressed air can provide. Both of these ways will be beneficial, but you will have to decide which is easier for you when picking out a plasma cutter.
If you have a plasma cutter without an air compressor, the air compressor you choose must adapt to your cutting demands and maintain consistent pressure for however long you need it.
You should consider several factors before buying powerful air compressor for plasma cutter. Here are the factors you should look:
While the amount of power in an air compressor doesn’t necessarily determine the best one, it plays a role. A pump with more horsepower will be able to maintain pressure and flow without slowing down or stopping because it can’t keep up with demand.
It’s important to look at the maximum capacity required by your cutter and find a compressor that is rated for at least this much.
This will allow you to continue working without having to wait for the tank to fill again when your cutting demands require more air than it’s able to provide instantly.
The bigger your tank, the longer you can work before needing to stop and refill with more air. This is especially important with portable compressors because power cords and extension cords often become limiting factors in how far away from an outlet you’ll be able to cut.
The larger the tank, the farther away you’ll be able to place the machine safely and still have enough power supply available if something goes wrong with your cord or your electrical source.
If an extension cord or power source does not limit you, then the size of the tank isn’t as important. Of course, if you have enough power available to support your cutter, it doesn’t matter what capacity your tank is.
Air pressure consistency
A compressor with better quality will keep air pressure stable through each cut so that there aren’t any sudden dips in the flow rate. Too many dips can cause damage to the machine and even fire if there is a spark present when the flow rate drops significantly.
The Fudge Factor
Fudge factors are always a great idea when buying air compressors for your plasma cutter. You should add 50% more than what’s needed because you never know how the environment will be, so it’ll ensure that whatever condition is given by its user won’t stop working properly.
Range of Work
As most users don’t use these machines for longer cuts, a small compressor with around 40 gallons will work but do remember if you start making longer cuts with that compressor, it won’t provide you with a satisfactory result.
If you’re a hobbyist or use the plasma cutter occasionally for your artwork or home projects, a small plasma cutter will be the best option for you.
Size of your Compressor
Compressors come in a variety of sizes. While the ideal Compressor is always the largest, this isn’t always what will fit into your workspace or meet your budget constraints.
You should keep in mind that you are the one who is ultimately responsible for keeping all of your tools working properly. Therefore it’s important to weigh portability against power and tank capacity so that you can choose an air compressor that is sufficient for your needs without being too heavy or cumbersome.
Another thing to consider before buying an air compressor for a plasma cutter is to know where you will use your plasma cutter. Some hobbyists or people who cut occasionally will not need a heavy-duty air compressor.
In contrast, those who need the machine for regular cutting of long cuts or thick pieces of metal or steel will need a heavy-duty and a more durable cutter. Also, you can use a smaller air compressor if you don’t plan to use it it to cut something for more than a minute at a time.
Plasma cutters that are frequently used should have an air compressor that is at least two times better than the system requirements of the plasma cutter itself to increase the quality of work.
What size air compressor do I need for the plasma cutter?
The right air compressor can make all the difference for your cutting projects.
If you’re a professional in the field of metal fabrication, then it is essential to have an air compressor that can provide non-stop performance for a long duration.
So if you need an extra high volume of airflow, then a 65 amp plasma cutter might be better suited than a 45 amp model.
It’s also important to look at the tank capacity in gallons. It makes sense that a larger air tank will be slower to refill, but it might be worth the wait if you’re cutting something massive and need extra time to finish your job.
This can be especially important for vertically mounted cutters since they take more time to fill.
For light-duty tasks cutting 20-30 gallons should be enough but if you do moderate or heavy-duty work, around 60 gallons should suffice depending on your usage.
It’s also good practice to have a backup tank so no matter what happens with the primary one, there won’t be any downtime in production.
Finding the right size of air compressor for your plasma cutter should not be difficult work if you know the air requirements of your Compressor. All you need to think of is your usage plan, and do keep in mind that always match the air compressor to the plasma cutter.
Don’t choose the opposite one. If the compressor you choose is tiny, you can burn out your Compressor or your cutter will get less air pressure and lose its efficiency.
Also, if the air quality is not excellent, your cuts won’t be of great quality, and you can even end up damaging your machines. So, to end it all, you will have to be sure that your air supply is precisely what your plasma cutter demands.
Is compressed air necessary for plasma cutters?
A plasma cutter is a tool that uses atmospheric pressure and electricity combined with cutting metal. However, compressed air is needed for it to work correctly. So yes, you will need an air compressor for your plasma cutter.
How much air pressure is required for a plasma cutter?
The amount of air pressure needed for a plasma cutter depends on the model of plasma cutter you have. Most models require between 90 – 120 PSI but it’s always best to check the specific requirements for your model.
How much CFM do I need to operate a plasma cutter?
You will need an air compressor that can deliver at least 4 CFM (Cubic Feet per Minute) at 90 PSI to run a plasma cutter. If you are cutting thicker metal, you will need more CFM.
What kind of air does a plasma cutter use?
A plasma cutter uses compressed air. The compressor doesn’t have to be very big, but it needs to deliver a consistent flow of air at the right pressure. Because plasma cutting requires a lot of airflows.
