Now, let’s get started with the reviews first!

What is a plasma cutter? 

Since you are looking for a plasma cutter, you perhaps already know what a plasma cutter is. As we have already mentioned that we want our readers to have a clear understanding of this tool, we would like to take the opportunity to reintroduce the tool for all types of users. Even though it's not possible to entirely describe all the factors of the plasma cutter in a few sentences, still we will try to address the key aspects briefly.

To begin with, a plasma cutter can easily cut any type of metallic material such as aluminum, steel, cast iron, and similar other materials. The idea of plasma cutting has been derived from welding technology.

Usually, the plasma technology cuts conductive materials using hot plasma. As the device is turned on the plasma torch works as the cutter. Starting from DIYer to technicians or mechanics use this device to create, repair or scrape types of tasks for small and big projects. More importantly, in recent types, the plasma cutter has been very popular in industrial CNCs as well due to its capability of fine cut in less time.

Types of the plasma cutter 

When you look up the internet searching for the plasma cutter, you will encounter different types. Which one should you go for? Well, to pick out the right one for you, you need to know what each type is suitable for. Below, we will introduce you with some of them briefly.

Mainly, there are two types of plasma cutters that can be found in the market. Mechanized and manual. Even though they cut metal with the same technology, there is a slight difference in application and set-up requirements.

Mechanized plasma cutter

This plasma cutter is used for industrial and manufacturing purposes. The mechanized cutters are computer operated and able to cut metal in a large sphere. Therefore, this plasma cutter is considered to be the best CNC plasma cutter for industrialists. It also comes with diverse features and is extensively powerful.

Manual plasma cutter​

Manual cutters are mostly used by DIYers and hobbyists for small projects or repair purposes. They are often found as a handheld cutter. So, if you need to cut light metals, steels or aluminum for repairing, home use, creative project, and maintenance purpose, you can use the manual cutter. The manual plasma cutters are handier and easy to use.

Now, based on the operational technology, there are mainly two types of torch commonly seen in plasma cutters in the market. And the difference is in the device’s cutting torches.

High-frequency torch

Basically, this type of plasma cutter produces high frequency as the device is started. As a result, it creates a spark using the high voltage transformer, and some other internal parts. So, the benefit of using this high-frequency torch type plasma cutter is, you can cut the metal at the targeted point directly. You don't need any additional types of equipment to work on your metal. However, you need to be careful from encountering any other electrical types of machinery.

Contact start torch

This type of plasma cutter comes with a nozzle. So, the electrical spark is created right at the pilot arc to cut the metal. It's very easy to use as soon as the device is turned on. And more importantly, this type of plasma cutter is not encountered with other electrical equipment.

So, these are the basic two types of plasma cutter torch. Besides, there are some other variations in plasma cutters in terms of features that you may find which are ideal for cutting different types of metal. Therefore, based on the user-friendliness mostly for DIY projects, below are some of the other types of plasma cutter available.

CNC plasma cutters

The CNC plasma cutters are quite popular these days due to its budget friendliness and easy application. A user can easily operate this device using a push button to cut any types of metal parts. However, you may also find two different types of CNC plasma cutter, one is Air Plasma Cutters, and another one is Mixed-Gas Plasma Cutters. So, depending on the thickness of the metal, either one of them is used.

Hand-held plasma cutter

As from the title, you may realize this plasma cutter is handheld. It means you can easily hold the cutter in your hand during use. Moreover, it's a portable plasma cutter that you may carry anywhere for any quick repairing, gouging paint or scraping work.

Semi-Portable Plasma Cutters

The semi-portable plasma cutter weighs less than 100 pounds. You can comfortably use this cutter for indoor and outdoor work. Like other great quality plasma cutters, you can easily cut metal with this device. However, it can cut up to 1-inch thick material.

Heavy Duty Plasma Cutter

Sometimes we need to cut a very thick material. Therefore, we need a strong and heavy duty plasma cutter. So, to work on such material which is more than 1-inch thick, you can use a plasma cutter with an acetylene torch.

How plasma cutter works

A lot of hobbyists' curious minds want to know how actually the plasma cutter works so amazingly. It's time to address it too. Actually, the technology is very simple.

Usually, a plasma cutter is constructed with plasma, cutting and shielding gas and torch electrode. And, most of the plasma cutters you find in the market are operated on compressed air. So, as you turn on the device an electric arc is sent through the opening.

This gas may vary from nitrogen, argon to oxygen. As a result of the electric arc, the gas temperature accelerates and raises it to the fourth stage. After passing through the stages the gas meets the plasma. Then, the plasma is transferred at high speed through a nozzle on the targeted metal to cut through.

So, overall this is the ideal technique of plasma cutter technology. There can be more process added for more benefits as the technical development emerges. But, this is basically how a plasma cutter works in most of the cutters.

How to use a plasma cutter? 

When you purchase a plasma cutter, you will definitely get a manual instruction inside the box. But, before you actually get such an item in your hand, you can prepare your brain beforehand for better understanding. Besides, if you have already seen or used a welding machine, you have nothing to worry about. The process of using a plasma cutter is pretty similar.

Below are the steps describing how to use a plasma cutter that you may follow-

Step 1: Choose a free and open space to work on metal. You need to ensure you can easily hold onto the metal safely during work.

Step 2: Turn off the unit and plug in the plasma cutter unit.

Step 3: Connect the Air compressor to the plasma cutter and attach the required fittings. 

Step 4: Turn on the air flow and secure the lever properly.

Step 5: Get a ground clamp and attach it near the work area.

Step 6: Turn on the machine.

Step 7: Set the current at the right frequency.

Step 8: Remove the safety and use the trigger to activate plasma.

Step 9: Put the torch or cutter close to the metal and allow it to cut. You can use a guide for a precision cut.

Step 10: Once the cutting is done, turn off the machine.

Step 11: Turn off the air using the liver.

Sep 12: Detach all the equipment and keep them in a safe place.

What are the accessories I need to have before using a plasma cutter?

When you purchase a plasma cutter, most of it comes with required accessories that you may need during application. Since different toolbox may come with different accessories, sometimes one or two items may not be included. Therefore, to help you use the device without missing any equipment, here we will take the opportunity to enlighten you what types of accessories are usually needed.

A machine cart or wheel kit

Well, this cart is not recommended for portable or small size plasma cutters. But, if you have a powerful cutter, then it may be of a bigger size and heavy. Therefore, to carry it easily you may need a machine cart or wheel kit.

A welding table

No matter what size of material you are going to cut, a welding table will help you keep the items in place. It will reduce the risk of losing items and also hold them securely for measurement or cut.

Head protector for the plasma cutter

When you use a plasma cutter, it becomes hot. Therefore, to protect it from overheating and catching the molten metal, the head protector will work as a shield. You need to attach the protector on the cutter torch.

Storage kit

In order to keep all the accessories and small items in place, you may need a storage kit.

Safety Tips for working with a plasma cutter 

We have already shared some tips you may consider to protect yourself from having an accident. And, to protect your important tool, plasma cutter, and metal from getting any damage. But, before you start working, you can go through the below tips for safety.

1. Wear protective clothing and headgear for protecting your eyes, face, head and the full body. Make sure the clothes are resistant to heat and fire. And for protecting your eyes, you may use goggles. Moreover, to protect your face, you are recommended to use a welding mask.

2. You are also recommended to use a welding helmet to secure your eyes from the bright light produced from the plasma cutter.

3. To protect your hand and feet, make sure you are wearing gloves, full trousers, and long sleeve clothes. Don't let your skin exposure to the plasma.

4. Before you start to work with a plasma cutter, make sure you are standing on a rubber mat.

5. Make sure the work location has a proper air ventilation system. Since plasma cutters work on gas, it may have health hazards during long use.

6. If you are using an electric plasma cutter, make sure there is no existence of water. Also, the work location is not wet. Therefore, always check the work location beforehand and make sure the place is dry.

What are the must-have things to consider to purchase the best plasma cutter?

So far, we have discussed all the background and basic information regarding a plasma cutter. If you have searched the internet, you will also find a wide variety of plasma cutters from renowned brands and extraordinary features and significantly with price variation. Now, does that make you confused how to find the best value plasma cutter from thousands?

Well, you may go through pages after pages searching for DIY plasma cutters or cheap plasma cutter reviews. However, you may still make the wrong decision if you don't know what features need to be there in your ideal plasma cutter. Therefore, to help you take the wise decision and evaluate your targeted plasma cutter before purchase, here we are going to present some of the key features for you to consider.

So, whether you purchase a plasma cutter from enlisted reviewed products or from outside, these features will certainly help you take the right decision. To know what feature we are talking about, keep reading!


Whether you are searching for the best cheap plasma cutter or the best 120v plasma cutter, the first and foremost thing you should check in a plasma cutter is the power. The price of such a tool varies due to the power specifications. Also, depending on the power performance, you will be able to know how thick metal it can cut and how fast. Therefore, when you are checking out your targeted plasma cutter, you must pay attention to its voltage and amperage.

So, if you are looking for a plasma cutter at a low price, you can choose one that comes with 110/120 volt and 40 to 50 amps. On the other hand, if you want a more powerful plasma cutter, you may choose 220/240 volt and up to 200 amps. Here, remember the later ones can cut very thick metal in less time, but they belong to the expensive category plasma cutter.

Built-in compressor

Another important feature you must not miss in your plasma cutter is having a built-in compressor. Because when you are using such a tool, you don't want an additional device for air or gas supply. It would be an added burden but nothing else. Therefore, to stay away from all the complexities, make sure the plasma cutter comes with a built-in compressor.

Metal Thickness

The next feature you should consider is the metal thickness the targeted tool can cut. So, if you need a budget-friendly cutter and you choose one with 40 to 50 amp, you can easily cut ¼ inch thick metal. Nevertheless, if you need a strong cutter to cut ¾ inch thick metal, then you should choose an 80 amp or more amperage plasma cutter. It means the more amperage and volt; the thicker metal it can cut. So, keep that factor in mind.

Cutting Speed

When you are using a plasma cutter, the quality of the cut also depends on the cutting speed. So, how do you know the cutting speed of your desired plasma cutter? Usually, it's not written on the toolbox. But, let me tell you a trick. Usually, the cutting speed depends on the amperage. It means you can easily understand how fast your device will cut comparing the amperage of the plasma cutter with one another.

Inches Per Minute

To understand how fast your targeted plasma cutter can cut through any thick metal, check out three things on the toolbox. Duty cycle, inches per minute and thickness of metal. For instance, if a device promises to cut a ½ inch thick metal with 10 IPM at 20% duty cycle, it means you can use the device to cut up to 20 inches without waiting for the device to cool down.

Indicators and Controls

Having indicators and control on a plasma cutter are very essential. Especially for the DIYers and hobbyists. In that case, you must check if the device comes with a power switch, an adjustable current setting, and indicators like LED and so on. So, look for such indicators in your plasma cutter and don't forget to check if they are user-friendly and positioned in the right place.

Automated Functions

When it comes to dealing with electronic tools and devices, who doesn't love comfort! Here, the automated functions on such devices ensure to assist the user. But, remember that the many automated functions are present in your device will increase the price of the device. Having said that, if the plasma cutter comes with an automated cooling fan or similar functions, it would be fun to use.


Since plasma cutters are used on metal and run on electric power, having the durability is a must. This durability is also related to construction material, design and usage time. So, when you are purchasing a plasma cutter, make sure to check every part of it properly.

Cut Quality and Performance

As already mentioned the cutting speed depends on the volt and amp. It also depends on how thick metal you are going to cut. So, to understand how finely and accurately the device can cut, don't just rely on the amp and volt. Rather, read through the specifications and reviews.

Inverter-based or not

All plasma cutters do not come with an inverter. Usually, the inverter-based plasma cutter is expensive. However, they can make the device lightweight and give protection against electrical fluctuations. So, if you are looking for a plasma cutter to use outdoors, you may choose an inverter-based plasma cutter.


If you decide to use your plasma cutter only for indoor projects, then you can ignore this feature. Also, if you purchase the best one for CNC (computer numerical control technology) for your professional use, this feature may not be needed for you.

But, some users tend to use the device indoors and outdoors. For them, portability is a major factor. Fortunately, you may find different sizes of plasma cutter in the market which will vary in weight as well. So, to have a portable plasma cutter, you can choose an inverter based cutter. Also, check if the device comes with a handle to carry easily.


Whether you are looking for a portable or indoor use plasma cutter, the device must be strong and durable for long term use. Therefore, you must check if the device is made of sturdy material.

Ease of use

If you are a DIYer or need a plasma cutter for home use, then this feature is important for you. If the device is complicated to use, it would be time-consuming and a hassle job. Therefore, to avoid all sorts of complications and risk of damage, check if the operating system of the plasma cutter is easy and user-friendly.


The versatility of the plasma cutter would depend on including the required and advanced features. If a device comes with all the automated functions, fast cutting speed, ability to cut metal or steel with any thickness would make it a versatile plasma cutter. So, check how versatile your plasma cutter is beforehand.


Since plasma cutters are operated with electric power or compressed, safety is a must. So, make sure the device is constructed ensuring safety for the users. Also, check if it's resistant to electric shock. Usually, plasma cutters use oxy-fuel, laser or water jet cutters to cut metal type materials. So, for safety, make sure your plasma cutter does not include any highly flammable gases.

Duty Cycle

The term “Duty Cycle” in a plasma cutter means how long it can run without any overheating. Usually, the duty cycle is mentioned in the toolbox. So, if you are looking for a plasma cutter for continuous use, make sure it comes with a higher percentage of the duty cycle. Because you don’t want to take frequent breaks while working with metal. Also, some cutters come with a cooling fan and thermal protection that also facilitate in having a good range of duty cycle.

Pilot Arc

Most DIYers love to use plasma cutters with the pilot arc. It's very easy to cut using the torch on the metal without actually touching it. Also, this torch helps to get a precise and clean cut on thin to thick materials. Even though such pilot arc oriented plasma cutters are expensive, this feature makes the product versatile, user-friendly and advanced quality.

Efficiency and accuracy 

Usually, the plasma cutters are designed and constructed in a manner to ensure accurate cut with proficiency. To get the best accuracy, you need to make a measurement beforehand. Compared to a laser-based plasma cutter, the air/gas based cutters make a more accurate cut without making any complicated adjustments. But, consider that lasers can make a more precise cut in less time.


By consumables we mean, when you use a plasma cutter, eventually some of its parts are damaged. And, they need to be replaced. Therefore, to ensure you don't need to purchase another plasma cutter, make sure it's parts are available in the market.


Whether you are searching for a cheap plasma cutter or best quality plasma cutter, the budget is very important. Usually, the price depends on the higher amps. But, if you are an amateur, yet looking for the best inexpensive plasma cutter, then you can search for such cutters within $220 to $500. Here, remember they may cut from ¼ inch to ½ inch thick metal.

But, if you need a powerful and heavy duty plasma cutter for a long time, then you may keep your budget from $1500 to $2000. These ranges of the device will help you cut 1-inch metal. However, we always recommend you to prioritize quality over price. So, it would be a good choice if you can be a bit flexible in terms of the budget while purchasing a plasma cutter.

What might happen if you don’t consider the must-have features 

No matter how much money you have in your budget to buy any product, we always want to get the best within that price. But, spending that money on the most popular product may not always be the best purchase. When it comes to purchasing tools like a plasma cutter, it's even riskier.

Because from the above discussion you already know there is a wide variety of plasma cutters in different features and prices. It's very difficult to identify the best among all when hundreds of the plasma cutters are available from renowned brands and highly popular. Therefore, no matter what your budget is, to pick the most suitable plasma cutter for your particular project, it's extensively important to pay attention to the must-have features. Otherwise, you would mistakenly take a decision prioritizing factors like budget, popularity or customer reviews.

Let me inform you, a 5 star in a product review may make the product a reliable one. But not considering the features may result in having a plasma cutter which does not have a long-lasting duty cycle or inverter. Moreover, if you need a plasma cutter for indoor use but due to the limited budget, you may purchase a portable plasma cutter without a built-in compressor.

And guess what! This would result in having an additional air compressor to supply air or gas to run the cutter. It also means having an added cost. Besides, you may check out features like IPM, duty cycle, cutting speed and power but did not think about durability or safety. Certainly, your investment in the plasma cutter may seem perfect initially. However, it may not last long or may cause damage to the material accidentally.

So, there are a lot of risks when you are intending to purchase a plasma cutter if you avoid the key features. Therefore, to make the best decision and a long term investment we are providing you the must-have features in detail. Hence, no matter whether you are searching for the best CNC plasma cutter for the money for industrial use or a handy plasma cutter for home use, these features will work as a guide for you to easily understand the product before and after you purchase.
