It's important to get the right plasma cutter with a built-in compressor for your projects, but the choice can be quite difficult. In this buying guide, we'll try to simplify the process and give you all the vital information you need to make the final decision. We'll go through all of the key features and look at how important they are to you. We follow this with some FAQs to get rid of any doubts.
How to pick a plasma cutter with built-in compressor
The first thing that you need to do is to assess your needs and know what you want to cut. If you are planning to cut thin metal infrequently, this will be a lot different from needing to cut through thick pieces of metal often. The power will play a crucial role in choosing the best plasma cutter, but there are other key considerations, such as the portability, duty cycle, and input voltage. As we go through each section, it's a good idea to note how important those features are to you. By the end, you'll have a clear idea on which model fits your needs.
The power of a plasma cutter is going to mostly come from the amperage that it has. This will determine the materials you're going to be able to cut. It is worth noting that different machines utilize that power in different ways, and, therefore, a low-powered cutter can often be better to use to achieve more accurate cuts of thin materials.
The Hypertherm Powermax 30 AIR Plasma Cutter is a great example of a plasma cutter that is high quality with a wide power range. It makes it perfect for a wide range of tasks. For most home uses, the 12 amps of the Hobart Airforce 12ci Plasma Cutter with Built-In Air Compressor would be more than enough. It’s recommended to look at the cutting capability, along with the power.
To get that high level of power out of the plasma cutter, you will need to make sure that it has proper voltage. The majority of residential power outlets in North America are 120v, which is perfect for a model, such as the Thermal Dynamics AirCut 15C Plasma Cutter, which is limited to that number.
If you tried the HeroCut HC3500 at full amperage in one of those sockets, you’d blow a fuse, as it would need 220v. A lot of newer American homes have a 240v supply, but this is usually for heavy-duty appliances such as ranges and wall ovens.
The duty cycle relates to how long you can use the plasma cutter in a 10 minute period. As these are machines which use a lot of power and get incredibly hot, you can’t use them for too long without them having a break.
The Hobart Airforce 12ci Plasma Cutter, for example, has a 35% duty cycle at full power. This means you can use it for 3.5 minutes continuously before needing a break. As you won’t always be using it at full power and continuously for minutes on end, this is simply a good guide to ensure the unit doesn’t overheat.
With cutting capability, you'll often see two figures, which will be the quality cut capability and also the severance cut. The Thermal Dynamics AirCut 15C Plasma Cutter, for instance, is able to make a perfect cut in metal, which is 1/8” thick. It also has a severance cut of 3/16". This severance figure is the limit of the cutter, and any cut that is close to it or even exceeds it would have a large amount of slag. The importance of this depends on the tasks you're doing. If you just want severance, then it doesn't matter about the quality of the cut, but most people will want nice clean cuts.
Weight, size, and portability
Plasma cutters with built-in compressors are often heavy, but there are be quite a difference between one model and the next. While some models are not that easy to carry around, the Hobart Airforce is pretty light at just 27lbs.
These plasma cutters are expensive machines, and the last thing that you want to do is to waste money on a defective one. You want to ensure that you have the guarantees in place should something go wrong or if your plasma cutter doesn’t have proper build quality.
The HeroCut HC3500 has a solid one-year warranty, but you can also get an independent warranty if you’re worried about it. It’s always a good idea to look at exactly what is being covered by your warranty as you don’t want any nasty surprises.
When you get your plasma cutter, it’s always a good idea to check that everything is there straight away and give it a test run.
You are going to have several consumables on your plasma cutters as parts will be replaced over time. This includes tips, electrodes, and shields along with other parts such as deflectors, retaining caps, and nozzles. It's always great to get a plasma cutter that comes with these accessories.
The Forney 250 P+ Plasma Cutter is a great example of a unit that comes with plenty of great accessories, including 10 tips and 5 electrodes.
There is a big difference in terms of price with plasma cutters ranging from the budget end to premium models. The Hypertherm Powermax 30 AIR Plasma Cutter comes in at a little under $2,000 but has the supreme quality and shows excellent performance.
It’s that’s too expensive for you, then the Thermal Dynamics AirCut 15C Plasma Cutter is a brilliant model at just over $1,000. It has good power while being easy to use as well as highly portable.
The Hobart Airforce 12ci Plasma Cutter with Built-In Air Compressor is a little cheaper at just over $700 and is a good mid-range option, which provides fantastic value for the money.
At the lower end of the scale, you have the Forney 250 P+ Plasma Cutter, which is just above $500. This model is great for beginners, and even without the highest build quality, it is still brilliant to use.
If you look at most air compressors, they are big, bulky, and hard to carry. If you were using this alongside a regular plasma cutter, then you probably weren’t able to move it around much or take it with you. Therefore, these plasma cutters are a lot more versatile.
Having a built-in compressor makes a lot of sense. It helps to make them extremely portable and much easier to use. It can often mean that you don't have the same level of power as if you used a compressor, but some models with build-in air compressors can still show excellent performance.
Due to how they work, plasma cutters can only work with materials that can conduct electricity. Therefore, you can’t cut wood or plastic with them. Instead, you'll be able to use them with a wide range of metals.
Aluminum, steel, stainless steel, copper, and brass are the most common materials that you can cut. The thickness of the material will depend on its density and the power that your particular model has. You can always check these parameters in the product description.
Your eyes will need a very high level of protection. This is not just from the sparks and molten metal from cutting but also from the intense light coming from the arc. You’ll need safety glasses to protect your eyes from these UV rays, or you can wear a helmet or face shield with special lenses.
For the rest of your body, you shouldn’t have any bare skin exposed. Durable, non-flammable clothing, such as jeans, is fine, but it's a great idea to get an apron for your upper body. High-quality rubber-soled shoes should be used, and a great pair of gloves is going to be vital for your work.
We have looked at a great collection of plasma cutters here, which range from great beginner models to much more powerful and robust machines.
We think that the best overall unit is the Thermal Dynamics AirCut 15C Plasma Cutter, as it has a good level of power, and it boasts an exceptional build quality.

The other two models we looked at here may well be more suitable for your project. All you need to do is work out what you plan on cutting and what features are going to be the most important to you. After that, you will be able to pick the best plasma cutter with a built-in compressor for you!
