Why Buy a Plasma Cutter?
As a motivation here are some reasons why you should buy a plasma cutter, if you don’t already have one
Wide range of Cutting materials
A plasma cutter is a tool designed to cut various metals. As long as you have a metal that needs cutting, the plasma cutter is the tool you need. You can cut nickel, steel, aluminum, brass, etc. with a plasma cutter. You get a wide range of cutting materials.
If you want to make all manners of accurate, perfect, and precision cuts in different positions, then you really need a plasma cutter. Do you want to cut sheet metal into different shapes? Then this is the tool for you.
Speed – Work Smatter
Are you tired of the time you spend on cutting metal? Try a plasma cutter. Its high-temperature ionized stream of gas used in cutting will greatly reduce the amount of time you spend in cutting metal.
Enough said, how does a plasma cutter work?
How Does a Plasma Cutter Work?
A plasma cutter sounds like the messiah of cutting metals, right? I know it does. Here’s how it works:
Basically, a plasma cutter works by sending an electric arc through gas as it passes through a small opening.
The gas used can be either air from an air compressor, oxygen, nitrogen, argon, etc.
Do you know there is a fourth state of matter? We all know about the three states of matter: gas, liquid, and solid. There is a fourth state called Plasma. This is what a plasma cutter uses.
The electric arc increases the temperature of the gas until it enters the fourth state, plasma. The electrical conductivity of the plasma causes the electric arc to transfer onto the metal workpiece.
The tiny opening (nozzle) the gas passes through forces it out at a very high speed. The high-velocity gas cuts through the molten metal. It is directed to the edge of the cutting area to protect the cut.
Types of Plasma Cutters
It’s always best to know about the various types of plasma products out there. It helps you in making the choice of what’s best for you.
Here are the types of plasma cutters you would see frequently when shopping for one:
Mechanized Plasma Cutter
This is also known as the CNC plasma system (CNC means computer numerical control). This plasma cutter is a machine that carries a plasma torch, a table and can move the torch in a direction directed by a computer.
The computer directs all the motions the machine makes based on a series of numerical codes in a program installed.
Most mechanized plasma cutters can be found in the manufacturing and fabricating industries.
These plasma cutters are not portable. Although they have the advantage of outperforming a handheld tool since the machine never gets tired.
Handheld Plasma Cutters
This is the plasma cutter most people are familiar with. These machines are connected with a nozzle that ends in a handheld trigger. Most handheld plasma cutters are portable. This means you will not be limited to job sites.
Hand-held plasma cutters are not as precise as their mechanized counterparts. But they can hold their own when it comes to cutting sheet metals of all kinds.
Artists, fabricators, DIYers, and contractors are generally the ones who favor this equipment.
For the purpose of this review, we will be focusing on the handheld plasma cutters.
And. here is one usual question I get from friends who wants to buy their first plasma cutter. This you would also find useful if it’s your first time!
Is an Air Compressor Necessary When Using A Plasma Cutter?
The answer to this question is yes! A lot of people don’t realize there is more to plasma cutting than just the machine.
An air compressor is an absolute must since it is cheaper to run your plasma cutter on compressed air.
It is worth mentioning that some light duty plasma cutters do not require an air compressor. But for many models on the market, a compressor is necessary to produce the pressurized air that will power the plasma cutter.
Before you buy an air compressor, you should select a plasma cutter first. Every plasma cutter has airflow and air pressure requirements in its specification sheets. You have to get an air compressor that meets these requirements for your plasma cutter.
If you do not match the compressor to the plasma cutter, you will not get the best performance out of your plasma cutter. Here is a guide for choosing the best portable air compressor.
Choosing the Best Plasma Cutter: What You Should Know!
Although you’ve learned so much about plasma cutters, you are not ready to buy one until you have considered the following factors:
The power specification of your plasma cutter is important. It determines the thickness of the metal your cutter can comfortably cut and how fast. The power depends largely on the voltage and amperage.
Most DIYers have cutters that are rated between 40-50 amps. These can typical handle most home repair tasks.
Professionals tend to have plasma cutters rated at higher amps. Depending on your needs, always remember the higher the amperage, the faster the cutter.
Also, you have to match the voltage rating on your plasma cutter to that in your work site. Most plasma cutters tend to have 110/120V ratings.
This is an important factor to consider. Due to nature and tasks your plasma cutter will be performing, an onboard cooling system is essential. This not only cools the internal components, but it also ensures that your machine lasts longer.
Check out for this when buying your plasma cutter.
Dual Voltage ability
Higher voltages usually require lower current to produce power. That is, 220V will require less current than 110V to produce the same amount of power.
Depending on the thickness of the metal you’re cutting, you might need to go up to 220V even though your home is wired for 110V. Or your home might have the 220V rating and you need to cut sheet metal. 220V becomes overkill.
This is where this dual voltage capacity in plasma cutters comes in. Many plasma cutters can work at both 110V and 220V. These machines are the best.
Buying a plasma cutter with this ability means you are not restricted by the voltage rating of your work site.
Type of Transistor
Plasma cutters will either have the Insulated Gated Bipolar Transistor (IGBT) or the Metal Oxide Semi-conductor field-effect transistor (MOSFET).
The choice of plasma cutter depends on the kind of transistor technology it has and how often you plan to use it. If you’re going to be bursting out your plasma cutter nearly every day, buy the cutters with IGBT. If not, then the MOSFET cutters are good enough.
Cutting Performance Parameters
This is perhaps one of the most important things to consider. Is the plasma cutter able to cut your desired thickness? How fast can it cut through the material? Most plasma cutters have the max thickness and max severance thickness listed.
Ensure that these figures match or are slightly above your cutting requirements. This will allow you to cut through your desired thickness faster.
Now you will find our plasma cutter reviews below. We give you 5 of the best plasma cutters out of the many we tested/Compared. Luckily for you, we considered all the factors above before rounding up this list.
