Plasma cutting: what is it?

Plasma cutting is a process of cutting electrically conductive metal using an accelerated hot jet of plasma. Plasma is ionized gas heated at high temperatures of up to 20,000 degrees celsius.

The three main plasma cutter types

Plasma cutters can be classified into three main types, pilot arc plasma cutters, high-frequency contact cutters, and computer numerical controlled cutters. Let’s take a look at each one of these three types of cutters and what they offer.

  • High-frequency cutters: These cutters use a high-frequency circuit to get the arc started. When using these cutters, the plasma cutter has to be in contact with the metal being cut.
  • Pilot arc cutters: These types of cutters require an electric source, and an electric current strikes the arc, typically Direct Current.
  • CNC cutters: These plasma cutters are used in industrial complexes and use a computer to make clean and precise cuts.

 What Can You Do With Your Plasma Cutter?

Plasma cutting is a process that is commonly used in metal workshops and out in the field. There are many things you can do with a plasma cutter. More importantly, there are many different types of cutters to choose from to suit your needs.

You will want something portable and has 15 inches to 20-inch leads for field use. This will allow you to reach your work and connect to an electricity source and air.

Below are some of the things you can do with a plasma cutter

  • House renovations that require cutting of metallic components such as removal of ductwork
  • Installation of art pieces, especially metallic art pieces
  • Overall machine maintenance and repair of automotive parts

Plasma cutters can also be paired with a CNC machine for intricate in-house projects. A CNC machine will allow you to produce cuts that are extremely precise and accurate.

Plasma Cutting Or Oxyacetylene : Which is better ?

Plasma cutting and oxyacetylene are used to cut through metals. So how do the two processes compare, and which is the better of the two? With regard to precision, plasma cutting takes the day.

Oxyacetylene involves melting the workpiece, which results in slag and will require some clean up afterward. Where oxyacetylene comes out on top is in the power department. While powerful plasma cutters can cut 2 inch thick metals, oxyacetylene can cut 24 inches thick.

The process you pick between the two will depend on your needs. If you need to cut 18 inch thick metals, oxyacetylene is the way to go. But if you want clean and precise cuts on different types of metal, go with plasma cutting.

What metals can You cut with a plasma cutter?

There are several different kinds of metals you can cut with a plasma cutter and these include

    • Aluminum
    • Stainless steel
    • Mild steel
    • Copper
    • Brass

What Other equipment do You need for Your plasma cutter?

While a plasma cutter alone can achieve its intended function, it is always good to pair it with other equipment for efficiency. The main equipment needed are;

  • Plasma cutting table: This table allows you to support your workpiece. It is also a better surface to cut on than on the floor or any other kind of surface.
  • Magnetic guide: this guide will come in handy when you want to make curved cuts. The magnetic guide will give you an accurate guide of a metal that you are cutting.
  • Eye protection: When plasma cutting, you need to wear a helmet or hood covering your eyes to protect them against sparks. Shaded welding goggles can be a great option for when cutting.
  • Flame resistant jacket: A flame-resistant jacket is another thing you will need when plasma cutting.

Steps on how to use a plasma cutter

Using a plasma cutter is fairly easy. There are no complications involved, especially if you are using a standard plasma cutter. Here is a step-by-step guide on how to use a plasma cutter.

Step one:

The first step is placing the metal to be cut on a safe surface. Ideally, you want a surface that allows for freedom of movement. A grate surface makes a great table to place the metal for cutting.

Step two;

The next step is plugging in the cutter to the power source. Before plugging it in, it is important to ensure that it is turned off.

Step three;

Step three entails connecting the plasma cutter to the air compressor. The purpose of this is to ensure the plasma jet maintains a high pressure. To connect the compressor, recede the outer flange of the female connection and insert the male connection. Then turn on the airflow.

Step four:

Next, attach the ground clamp near where you will be working.

Step five: 

Once this is done, turn on the machine by switching the on/off switch to on. Next, set the current level, depending on the thickness of the metal.

Step six;

Turn on the nozzle of the cutter using the trigger. It is important to note that you will have to lift the trigger’s safety before turning the nozzle on.

Safety hazards to be aware of !

  • Hot metal and sparks are blown out during the initial piercing of the metal.
  • The high temperatures produced heats up the workpiece and cutting torch.
  • The plasma arc is hot enough to burn through gloves and skin.
  • Sparks and heat generated can ignite any near flammable material.

Clean cut vs. severance cut; what is the difference?

When you cut a material smoothly and evenly, the resulting finish will be smooth and even on all sides. This is what is called a clean cut. A severance cut, on the other hand, produces a coarse finish that is uneven.

What Is The Plasma cutting consumables?

The consumable in a plasma cutter is made up of several components. They include the nozzle, electrode, swirl ring, retaining cap, and shield cap. Each of these five components has a part to play in the consumable’s function.

The swirl ring is found inside the torch, and its main purpose is to swirl the gas surrounding the plasma arc. The purpose of this is to ensure the arc is focused and directed to the workpiece for improved precision.

The electrode is a piece of copper that contains an electrically conductive element known as hafnium. The purpose of this component is to receive the electric current.

On the other hand, the nozzle is the part of the consumable the directs the gas and plasma arc for making a precise and clean cut.

The function of the retaining cap is to hold all the parts of the consumables together. On the other hand, the shield cap’s job is to protect the torch from sparks and molten metal.

How often should You replace the consumables?

The consumables of a plasma cutter wear out over time and need replacing as the nozzle, and the electrode is in direct contact with the hot plasma; they wear out quickly. When these two parts wear out, you will notice the hole in the nozzle becomes larger.

When you notice this hole has increased in size and your cuts’ quality has worsened, it is time to replace the consumable. How frequently it should be done depends on how often you use the cutter.

How much does a plasma cutter cost?

Plasma cutters can range from $50 to over $100,000. However, the average plasma cutter will cost anywhere between $100 and $1000. For most homes, the cost ranges from $300 to $500.

The best plasma cutter under $500 will typically have all the features needed to cut metals that are less than 1 inches thick. On the other hand, the best plasma cutter under $300 will be able to cut thinner metals.

Do You need a plasma cutter with a built-in air-compressor?

Plasma cutters need an air compressor. When the plasma cutter arc heats the metal, the plasma is forced out by compressed air to cut the metal. This is the reason you need an air compressor.

Buying a plasma cutter with a built-in air compressor will save you the time and hassle of having to buy a separate piece of equipment. It is worth noting that plasma cutters with built-in air compressors tend to be pricey.

Nevertheless, a built-in air compressor is a great feature to have in a plasma. After all, you still need to get an air compressor.

110v and 220v plasma cutters: what is the difference?

The main difference is in the amount of power a plasma cutter has. A 220v plasma cutter has a higher voltage and can thus output a higher amperage. On average, a 220v machine can output 30 amps and overpower. A 110v cutter is less powerful.

Tips on how to maintain your plasma cutter

  • Examine the torch and its parts by removing them and checking for any noticeable damage and also clean out the inside of the torch
  • Clean the power supply components using compressed air to ensure they are free of dirt and debris
  • Use a degreasing agent to clean the cutter’s components, including the rails, gears, and racks.


Plasma cutters are valuable tools to have around your workshop or even home. They can cut a wide variety of metals. The best thing is that you do not need to spend a fortune to enjoy the benefits of a plasma cutter.

The best cheap plasma cutters we have reviewed above will serve you well without breaking the bank.
