Science has discovered plasma in 1879. But who had known that this will be a tie-breaker between the stiffness of metals and effort of humans?
With the help of a plasma cutter, it’s possible to cut any metal like a knife cuts butter.
If you are a mechanical worker or interested in artistic metal works or has a small workshop, you can’t ignore the necessity of a plasma cutter.Having one of this will speed up your work to a great extent as well as give you release from the hassle of manual cutting.
But as you are now on this page, you may be determined to have one of them, but confused which one. Right?This is natural. Because you will find a plethora of them out there.
But the mammoth question is, which one worth the money?
That is why we are here to introduce you with the top ten plasma cutter by this time.All of them have proven record of professional performance. So, I hope by the end of this plasma cutter review, you will get a clear picture of them.
Things to Consider Before Buying the Best Plasma Cutter
We have researched for weeks to make our list of the best plasma cutting tool. All of the cutters of our list are best from a different point of view. So, not every cutter will be suitable for everybody. But if you answer the following questions, picking up the best one for you, will be much easier. So let’s discuss the criteria.
1. How Much Cutting Depth Do You Need?
This is the most important fact that you should consider first. So, are you a professional mechanical worker or mechanical works is just your hobby?
Let’s assume you are a professional worker. Then you are going to need a machine with more deep cutting capability. Because you will often require cutting deep holes or lines into plates.
Moreover, if you want to use the cutter in an industry, a cutter with less deep cutting capability may give rise of problems. So, at such condition, you should prefer a cutter that has minimum severance cutting capability of one and a half inch.
On the other hand, if you are just an artistic worker and works at home, without some uncommon cases, it won’t require having a cutter having more than 3/8 inch severance cutting range.
2. What Is The Rating Of Your Voltage Rating?
If you work at home, then you should choose a cutter according to the supply voltage that you have there.
But if you are in service, you may have a problem with a fixed voltage rating machine. So at such cases, you must have one that runs with both 110 V – and 220 voltage rating. Again, this type of dual voltage cutter works on both 50 and 60 Hz frequency. So, having this type of cutter will give you more flexibility.
For industrial work, you can choose according to the supply voltage of your industry.
Although most of the plasma cutter has variable voltage operation for those which don’t have this capability using a converter will solve this problem.Some of them have built in converter that automatically adjusts the voltage. So choosing these will be wiser.
3. Will It Be For Personal Or Professional Purposes?
The rating of the machine varies in case of personal and professional use.
When you want to use the machine for your personal purposes such as artistic works or repair work, you can take as much time as you need. So you needn’t worry about the cutting speed.
But when you are a professional worker, you must be more time efficient.
So in this case, choose that one which has more plasma flow rate. You can easily identify them from their air pressure. Generally having the air pressure of 75 Psi or more is considered to be suitable for speedy work.
4. Do You Need A Multipurpose Plasma Cutter?
Repair work sometimes doesn’t only requires cutting, but also need to be weld. So having a welding machine built with plasma cutter speeds up the work to a great extent.
Fortunately, some of the plasma cutters have this functionality integrated with them. So, if don’t want to spend money behind a welder separately, you can choose one of them.
5. What Are The Materials Type That You Will Work With?
Although all type of plasma cutter works fine with all type of metals, some of them have greater efficiency with a specific type of metals.
As for example, some cuts the alloy materials well, usually these type of plasma cutter has strong cutting power. On the other hand some works with no ferrous metals, like aluminum, cobalt, nickel, and copper.
So you need to choose according to the materials you have to deal with.

How Does a Plasma cutter Work
Plasma cutting technology was first invented in 1950 and the commercial application was first introduced in late of 1960. After that, it has gone through many evolutions. But the basic mechanism is the same.
A plasma torch has three main component. The torch electrode, cutting gas and the gas shield.
The gas can be oxygen, nitrogen or even clean air. The gas doesn’t have any major effect one the cutting performance.
The mechanics of a plasma cutter is simple. This one works like a cork borer. An arc of plasma acts like a borer and spins through the metal plate to cut it.
As mentioned before plasma cutter uses gas for operation. The gas transforms into plasma due to the high temperature.
The target metal plate that we want to cut act as an anode. And the plasma torch has a cathode inside it. So both of them are the parts of the circuit.
As plasma is nothing but the same amount of positive and negative ions, they are highly conductive of electricity.
When the restricted opening lets the pressurized gas to be out from the opening the plasma transfer the work to the metal plate as the electric circuit that is consist of the torch and the target metal plate full filled.
And as the plasma has very high temperature, the metal melts and the plasma borer easily penetrates the malted plates. There is also a flow of shield gas that protects the area you are cutting by the torch.
Some of the modern plasma cutter uses pilot arc torch. This torch uses ionized gases. This ionized gas provides a better shield to the cutting area.
For initializing the torch, at first, it needs to be tip to create the spark. Because of doing that, a high-frequency electric circuit starts. This works like a spark plug.
But some of the best plasma cutters for CNC machines doesn’t require this initialization. They did this automatically.
Plasma Cutter Safety Guide
Plasma cutters can be small in size but they have massive power. If you are reading this article from the beginning, you already know that some of the cutter uses 5.5 kW energy per hour. So, this thing is not a toy. You must follow some safety guide for your own wellbeing.
1. General Safety
Don’t allow anybody does stay close to the cutter, especially children’s and those don’t have knowledge of this machine.
When you began to work with a plasma cutter, let everybody around you know that you are starting. And look for if there is any explosive gas out there.
Always keep a fire extinguisher around you.
2. Personal Safety
You must wear necessary fire protective suits before working with a plasma cutter.
As plasma cutter creates highly intensive light, using them with the naked eye can harm your retina and has a higher chance of being blind. So always wear a helmet with proper eye protection or at least a glass.
But for the best, you can use an automated darkening plasma cutting helmet. Although it will cost you some money, for better protection taking this will be wiser.
3. Eye Protection Chart
|Ampere Rating||Minimum Shade Number|
Plasmas are highly heated gas that they create ions. As a result, the plasma torch becomes very much hot quickly. So always use gloves to protect your hands from burning.
As it needs to complete the circuit to work with a plasma cutter and the target plate is a part of the circuit. You must confirm that you are insulated from that.
4. Machine Safety
Always use clean air for cutting. Air having fumes or dust can cause a hazard. Never ever work in a damp weather. You may get an electric shock while doing that. Standing on a rubber platform, while working with a plasma cutter is recommended.
Always work proper ventilated places and while cutting the coated metals, remove the coating first. Finally, never use excessive pressure and use the machine longer than recommended time.
Finally, we are at the bottom of this long review. As you have read this far, now you know all the necessary information and key points that make a plasma cutter for your own purposes.
This is true that each of these machines has some handicap. But if we measure their performance, the handicaps are negligible. Again the main reason, that we have accommodated them in our top ten list is because of their proven performance.
This is obvious that not all of them will be suitable for everybody but for somebody. So, your task is to figure out the most suitable one for you using the guide that I have provided you at the very first of this review.
Hope this guide was helpful.
Thank you for reading with patience.
