Best Plasma Cutter – Buyer’s Guide

A plasma cutter is one of the best tools to buy if you need to cut steel and other metals.

It might be dangerous if you don’t know how to use it because to cut through metal, it uses inert gas that comes out of a nozzle at a very high speed. Plus, at the same time, an electrical arc is created to turn the gas into plasma. 

As a result, you get a hot torch that is incredibly powerful and can help you create beautiful items out of a single sheet of metal. 

With such a result, as you can see, these appliances have to be high-quality and durable. Choosing a plasma cutter is very important for its proper work and your safety. There are many factors that are combined in the best choice, and to make it easier for you, we’ve chosen 5 great cutters for different purposes.

Some of them are heavy-duty, while others only cut through thin sheets of metal, are lightweight, and portable.

After the list, there’s a buyer’s guide that will explain to you all the factors to consider before making the final choice. After combining them in one bowl, you’ll get a description of a perfect plasma cutter for your purposes.

Best Plasma Cutter – Buyer’s Guide: Factors of Choice and FAQ

To make the best choice, you have to know which criteria to apply. Here, we’ll talk about the most important things both amateurs and professionals have to think about before buying any plasma cutter.

​Environment You’re Working In

​While humidity and temperature aren’t the deciding factors, the air quality is. If you’re working in a relatively clean environment with normal air that’s not dusty, any plasma cutter will be good.

However, if it’s an industrial construction site and there are a lot of metal shavings, dust, and debris, you need a cutter with an in-built fan. It filters the air and removes dust and waste from it before it gets into the unit.

Dirty air might clog the device and jeopardize the results of your work. The cutter’s durability is also at stake.

There’s also a wind tunnel technology that offers advanced air cleaning and better cutting results.

Duty Cycle

First of all, determine what kind of duty cycle you’ll need: 

  • Using the cutter frequently but for a short time in one session;
  • Using it continuously for a longer time in one session.

If your choice is the first one, your main priority should be the amperage output of the unit. The more output there is, the higher its duty cycle is.

If you choose the second option, the main factor is the maximum thickness of metal the cutter can work with. Usually, in the descriptions of such products, you can find information about the metals the unit can be used for and the maximum thickness of metal it can handle.

​​Cutting Speed and Quality

A combination of suitable cutting speed and quality is also something to pay attention to when choosing a plasma cutter. There are three main cutting qualities:

  • Rated cut.
    This is the best type for light-duty work; it provides a clean and quick cut. It’s used for medium thickness to thin metal sheets.
  • Quality cut.
    This cut is suitable for thicker metals and also provides clean results. However, you need to use it for a longer time to achieve results.
  • Severe cut.
    The severe cut is used for heavy-duty work with thick metals. It works very slowly due to the thickness, and the final cuts aren’t of the best quality and require touch-ups.

Keep in mind that the thinner the metal becomes during work, the faster your cutter will work.

Input Power

Plasma cutters are manufactured to be suitable for two types of outlets: 110 volts and 220 volts. It’s recommended to have a separate circuit for the unit since the power may go down if any other appliances are plugged in, reducing the efficiency of the cutter.

Also, pay attention to the amperage ratings in the descriptions before buying a cutter. Your cutter has to have a suitable minimal amperage for the outlet you’ll be using.

Start Type

There are two main start types for plasma cutters:

  • Contact start;
  • High-frequency start.

Contact start allows you to see the pilot arc and position it better. It’s also safe for other appliances you have in the room, like telephones, TVs, radios, etc.

A high-frequency start creates interference, which may be dangerous for other electrical devices. It’s not safe to use it if you have a lot of appliances in the room. However, it’s very powerful and also allows for precision and fewer sparks.

​Air Supply

​If you’re using a portable plasma cutter, normal air or nitrogen can be used. Some users choose to carry compressed air or nitrogen in bottles and attach them to the cutter whenever needed. Nitrogen is said to cause less oxidation; it’s also more affordable than regular bottled air.

However, if you need maximum portability from the device, look for one with an in-built air compressor. It will use the air around to do the job.

Carrying bottles around and reattaching them is both time and effort-consuming, not to mention the financial factor.

In-built air compressor

​Portability

If portability isn’t your priority, and you need a relatively stationary plasma cutter, you can skip this part. However, lighter weight and ease of use add to the overall comfort of your workplace. 

In case you have to carry the device to the metal that has to be cut, portability becomes very important. Newer models offer superior functionality and light weight to accommodate all kinds of use. 

Control Panel

​The control panel is what allows you to operate the device. All cutters have one, but you should opt for a panel that is easy to understand, even for a beginner. This will ensure ease of use of the device and more functionality opportunities.

Some people can’t understand indicators on the control panel of their cutter and can’t use the unit to its fullest. There might be essential functions hidden behind those indicators.

Another great recommendation is to read the user manual fully before assembling and using the device. The instruction should explain all of the indicators and buttons on the control panel, as well as other important things you have to know about the model.

Even if you’re a professional, consider reading the manual till the end.

​Built-In Inverter Availability

If you’re working at different sites or a place with no suitable power outlet, you need a plasma cutter with an in-built inverter. Such details can convert DC power and use electricity through a high-frequency transistor-inverter. The range of use is quite wide, from 10 kHz to about 200 kHz. 

Such plasma cutters are generally more expensive, but working with a standard one will be troublesome if you offer mobile services or work at sites with various power outlets. Such units are also highly portable because the housing is made smaller to accommodate the high-frequency operation.

FAQ on Plasma Cutters

Here are some more answers to your potential questions.

What gases can I use for a plasma cutter?

You can use:

  • Air;
  • Nitrogen;
  • Oxygen;
  • Argon.

There are also mixtures of these. You need one that will pass through a tight opening.

There are cutters that offer “dual-gas” or “multi-gas” capabilities. These are great for people working with a variety of metals where different gases and their mixtures are used. The more gases a cutter can use, the more flexible it is. 

Using proper gas will help you balance the overall productivity, cost, parts life, cut speed and quality, etc. 

What can be cut with the appliance?

A plasma cutter will work on any material that is electrically conductive. Usually, steel (regular or stainless) or aluminum is used. Additional metals can be brass, copper, and other conductive types.

Is there anything to know when cutting aluminum?

The choice of gas is the most important thing to know. For aluminum, pure nitrogen should be used. If there’s none, you can also use a mix of nitrogen and oxygen. These gases will improve part life and cut quality.

There’s only one problem that might occur – oxidation of the material. However, nowadays, you can find technologies that will prevent that. It’s also wise to consult a professional to optimize the work.

Is it possible to use a plasma cutter for welding?

Some 3-in-1 plasma cutters offer opportunities for TIG and MMA welding. However, professionals recommend buying a separate welding device and not using multipurpose appliances. If you’re only going to need to weld occasionally, a 3-in-1 model will do.

​Conclusion

​There are many factors and details in the choice of a plasma cutter. The device is incredibly powerful and can help you with anything from industrial constructions to art installations. The most important thing is to buy an appliance that suits its purpose will serve you for years.

Out for quality, not price. Buying according to your estimated budget is great, but don’t hesitate to invest in a high-quality, reliable, portable, and highly functional model.

Maintain it, buy replacement parts in time, and contact the manufacturer if something unusual happens. Some machines leak air with time, or there might be other issues. Make sure you take care of them.

Also, pay attention to the user manual included in the package. Even if you’re the best professional in your city or country, you should remember that every appliance is different. There are new technologies integrated into the newest models; you might not even know about them yet.
