Buyer’s Guide: All You Need to Know About The Best Plasma Cutter

How Does A Plasma Cutter Work

How Does A Plasma Cutter Work

They work only by sending an electric arc through a gas that needs to pass through a very narrow and constricted opening. What happens is that when the gas is passing through such a narrow opening, its temperature significantly elevates, and it enters into the fourth state of matter.

Material scientists have named this fourth state of matter as the plasma state. It comes after the tri-state of solid, liquid, and gas.

Because the gas is squeezed through the narrowest opening, it comes out at a very high temperature (a whopping 45,000 F) and very high speeds (20,000 feet/s). This high-speed gas can cut through any molten metal. The metal is also a part of the circuit, and the electrical conductivity of the arc gets transferred to the work.

Cheap plasma cutter will have the gas-directed around the perimeter of the metal in order to shield its cutting area. But there are top-rated plasma cutter on the market today that sends a pilot arc between the electrode and the nozzle through which the gas escapes and that ionizes the gas. The result is that the plasma is generated much ahead of the arc transfer.

What Kind Of Gas Does A Plasma Cutter Use

People use a lot of gases for plasma cutting

What Kind Of Gas Does A Plasma Cutter Use
  • Shop air
  • Nitrogen is usually preferred for cutting through Stainless Steel and Aluminum
  • Argo and hydrogen in a mixture is used for cutting through the thicker Stainless steel and Aluminium
  • Hydrogen and Nitrogen mixture or Methane and a Nitrogen mixture are used for neat cutting thinner sheets of stainless steel.
  • Oxygen is most often used for cutting mild steel and carbon steel.

What Size Plasma Cutter Do I Need

Try asking yourself these two questions:

  • What is the maximum thickness of the metal that you will be cutting?
  • How fast do you want your cutting to be?

Just like welders, voltage and amperage are essential determinants in choosing the best desktop plasma cutter or even a handheld plasma cutter. An efficient tool needs high voltage and low amperage.

If you are looking to cut metals using the tool, then you must go in for a unit that is greater than 40 amperes. Use a regular tip with a built-in drag shield. If you intend using it for bevelling, cutting in corners, or a place where you need to see where the plasma is cutting, go for an extended tip in a unit that has less than 40 amperes.

How To Choose The Best Plasma Cutter

How To Choose The Best Plasma Cutter


The right size will depend on the material that you want to cut and the table where you will place it. A small CNC plasma cutter is as efficient as a big manual plasma cutter, so size is not so much important as its efficiency, but the power output is.


A lightweight plasma cutter is preferable if you want to carry it around the place. If you are going to use it on the garage table, it does not so much matter. According to conservative estimates, it should weigh in the bracket of 25 and 35 pounds. Anything more than this will be too bulky to carry around.

Power Source

Professional cutters will be with a maximum of 40 amperes and more, even the best MIG welder. However, if you are looking for your home or your passion, then a 12 to 25-ampere that operates within 110V and 240V is good, to begin with. A 30-ampere breaker can also give you an equal cutting capacity from the dual voltages. Check out the best 110V plasma cutters on our list.

Duty Cycle

The most ideal duty cycle is 10 minutes. It is usually expressed in percentage and tells you how long that machine will work without overheating.



Lightweight cutters are a boon. They can be carried everywhere. Home CNC plasma cutters with handles that are impact-resistant and those that come in a hard carry case are the best in terms of portability.

Cutting Ability

They can be used to cut all conductive metals and are not restricted to the common ones like stainless steel, copper, and aluminum. They can cut thin sheets gauge to thicker slabs with elan.

Cutting Performance

All of them, whether manual, handheld, or CNC, is equipped with cutting thin and thick metal slabs. They can make ½’ of clean-cut and a severance cut of ¾ inches. They can make neat cuts and are relatively safer than the erstwhile methods of cutting metals.


Most of them come with a sterling three-year warranty. The extended warranty speaks for itself. A manufacturer that is ready to take an undertaking for as long as three years is sure of the quality of the product that he is selling. Warranty is one of the factors you should look out for.


These are not exactly cheap. You can get some of the best models are in the range of $250 and $500. It is a good idea first to determine what kind it is that you are looking for. Doing your homework is recommended so that you can filter out the choice one by one.

Best Plasma Cutter Types

Manual Plasma Torch

Manual Plasma Torch

Several plasma cutter brands make handheld PAC systems that are incredibly lightweight and portable. They are quite powerful for their size and are capable of cutting anything from thin gauge wires to thicker metal plates of about 1 inch. The Manual plasma cutting torch is the fastest-growing segment in the cutting industry today. It is fast, efficient, and excessively affordable too.

They are usually high frequency starting circuits and come with a built-in power supply. They use higher voltage, and they have an on/off switch along with an amperage adjuster switch too.

Automatic Plasma

Automatic Plasma Torch

Computerized plasma cutter is a CNC (computer numerical control) plasma cutting torch that gives you greater flexibility at cutting a more diverse range of shapes. They are a notch above the manual ones. They execute the cutting by basing it on instructions that are pre-programmed by a computer.

The CNC machines figure on our list as some of the best plasma cutter 2021. They come in all sizes, very small to the professional ones, and even those that can be used around the house.

Using them is as easy as using a glue gun and as difficult as precision welding. Follow the steps carefully to ensure you get a clean cut devoid of any dross accumulating at the bottom of the metal cut

  • Place the frag shield on the edge of the base metal that needs to be cut
  • Adjust and hold the angle straight down and at the correct distance (usually 1/8th).
  • Try to direct the arc straight down without dragging initially
  • Raise the trigger lock and press it; the pilot arc should start immediately
  • Once you have the pilot arc starting, move the torch across the metal
  • Adjust the speed optimally. If you go too slow, the cut may have too much dross. If you go too fast, your cut may not be neat.
  • When you reach the end, angle the torch slightly in such a way that you can pause briefly before releasing the trigger and completely severing the metal.
  • When you off, post air will begin flowing to cool the torch. This will happen for 20-30 seconds. Do not press the trigger now, or else the arc will spark again.
They are the most effective way of cutting thin as well as thick metals. If we are talking about manual mini plasma cutter they can cut up to 38mm that is 1.5 inches thick steel plates. A stronger best plasma cutter for CNC can neatly and safely cut up to 150 mm or a whopping 6 inches thick steel plate.
In theory and practice, both the mobile plasma cutter and the tig plasma cutter are two different tools. While the TIG welder melts two metals together, the plasma cutter cuts neatly one slab of metal into two. However, there is a certain plasma cutter combo where the TIG welder can be altered to be used as a plasma cutter. The user should beware of open flames and must have protective equipment and always observe safety precautions, therefore we recommend that you buy along with this best work gloves. Not forgetting the safety, do not forget to also choose the best welding helmet for yourself.
Yes! It will do a neat job out of a rusted metal slab as well as a slab of stainless steel. It is good for dirty as well as painted surfaces!
