Do All Plasma Cutters Need Air Compressor
No, not all plasma cutters need an air compressor. Some smaller, portable models can run off of a standard household outlet. However, industrial-grade plasma cutters almost always require an air compressor to function properly.
If you’re in the market for a plasma cutter, you may be wondering if you need an air compressor to go along with it. The answer is maybe. Some plasma cutters come with an integrated air compressor, while others require a separate unit.
If you’re not sure which type of plasma cutter you need, consult your user manual or the manufacturer.

How Big of a Compressor Do I Need to Run a Plasma Cutter?
Plasma cutters are a great tool for anyone who needs to do precision cutting or etching on metal. But before you can start using one, you need to know how big of a compressor you need to run it. Here’s what you need to know.
The size of the plasma cutter’s compressor is going to depend on a few different factors. The first is the amperage of the cutter. The higher the amperage, the more air the cutter will use and therefore the bigger the compressor will need to be.
For example, a cutter with an amperage of 40 will require a much bigger compressor than one with an amperage of 20.
Another factor that will affect the size of your compressor is whether or not you plan on using extended runtime accessories with your cutter. If you’re planning on using an extended tip or nozzle, for instance, then you’ll need a bigger compressor so that it can keep up with the increased air demand.
Finally, consider how often you plan on using your plasma cutter. If you only plan on using it occasionally, then a smaller compressor may be sufficient since it won’t have to work as hard as one that’s in constant use. However, if you’re going to be using your plasma cutter frequently or for long periods of time, then a larger compressor will be necessary so that it doesn’t overheat and shut down from being overworked.
In general, most people who are going to be doing occasional light-duty cutting can get by with a small air compressor that has at least 2 horsepower (HP). For more frequent or heavy-duty use, look for something with 3 HP or more so that it can handle the increased demand without problems. And if you plan on using extended runtime accessories like tips and nozzles regularly, make sure your chosen model has enough power (4 HP or more) so that it won’t struggle to keep up with them.
How Much Air Pressure Does a Plasma Cutter Need?
A plasma cutter is a power tool that uses a stream of high-velocity ionized gas to cut through electrically conductive materials. The gas is typically composed of argon, hydrogen, nitrogen or oxygen. Plasma cutters require a constant supply of compressed air in order to operate.
Depending on the model and manufacturer, plasma cutters can require anywhere from 2.5 to 6 CFM (cubic feet per minute) of air flow at 90 PSI (pounds per square inch).
Most home workshop compressor setups will not be able to provide the required volume or pressure for running a plasma cutter for any extended period of time. For this reason, it is recommended to use a dedicated air compressor when operating a plasma cutter.
These compressors are specifically designed to provide the high volume and pressure needed by plasma cutting equipment.
What are the Two Types of Plasma Cutters?
When it comes to plasma cutters, there are two main types that you need to be aware of. These are the portable plasma cutter and the CNC plasma cutter. Each one has its own unique set of benefits that can make them ideal for different projects.
Let’s take a closer look at each type so you can decide which one is right for you.
Portable Plasma Cutter
A portable plasma cutter is an excellent choice for those who need a versatile cutting tool.
This type of cutter is small and lightweight, making it easy to transport from one job site to another. They’re also relatively affordable, which makes them a great option for those on a budget.
One of the biggest advantages of a portable plasma cutter is that they’re very easy to use.
Even if you’ve never used one before, you should be able to get the hang of it quickly. They also offer a high degree of precision, so you can rest assured that your cuts will be clean and precise.
CNC Plasma Cutter
A CNC plasma cutter is a more sophisticated version of the portable model. This type of machine is computer-controlled, which means that it can produce very intricate designs and patterns. If you need to cut complex shapes or detailed patterns, then this is the machine for you.
Do All Plasma Cutters Require Gas?
No, not all plasma cutters require gas. Some models are designed to work without gas, using only air to create the plasma arc. These types of plasma cutters are typically used for lighter cutting applications and are less expensive than their gas-powered counterparts.
Baby Air Compressor? Can You Plasma Cut With It!
Cheapest Plasma Cutter With Built-In Air Compressor
There are a few factors to consider when purchasing a plasma cutter. One of the most important factors is the price. Another factor to consider is whether or not the plasma cutter has a built-in air compressor.
Some people may also want to consider the weight and size of the unit.
The cheapest plasma cutter that I could find was around $200. It did not have a built-in air compressor, so keep that in mind if you’re considering this option.
The next cheapest option I found was around $250 and it did have a built-in air compressor. This might be a better option for you if you don’t want to worry about connecting an external air compressor.
The weight and size of the unit can also be important considerations, especially if you plan on moving it around often or taking it with you on job sites.
The unit I found for $200 weighed in at around 40 pounds, while the unit with the built-in air compressor was closer to 50 pounds. So, keep that in mind when making your decision.

How Does a Plasma Cutter Work
If you’ve ever seen a welder at work, you know that there’s always a lot of sparks flying around. But what exactly are those sparks? They’re actually plasma, and plasma cutters use this hot ionized gas to cut through metal.
How does it work? Well, first an electric arc is created between the cutter tip and the metal. This creates a plasma channel that is superheated to around 30,000 degrees Fahrenheit.
That’s hot enough to melt most metals!
The cutter has a nozzle that constricts the plasma flow, making it even hotter and more focused. This allows it to quickly slice through thick metal plates with ease.
And because the plasma is so hot, it actually seals the edges of the cut as it goes, so there’s very little cleanup required afterwards.
Plasma cutting is a quick, efficient way to get through tough metals – and with modern machines, it’s easier than ever before. So if you need to make a quick repair or modification on something made of steel or aluminum, reach for a plasma cutter!
