What Is Plasma Cutting?

It is the process of making use of electronically ionized gas, otherwise known as plasma, to cut through material that is electrically conductive. You may typically use this technique to cut through metals such as:

  • copper,
  • stainless steel,
  • aluminum,
  • brass and
  • iron.

This method of cutting through metal is incredibly effective, and many people across industrial and construction industries use it in carrying out their activities. As a small construction business owner or DIY enthusiast, you may also find it incredibly useful in your workshop.

If precision and speed are important to you, it will definitely be worth your while to consider adding a plasma cutter to your supply of tools and equipment. The running costs of using these products are incredibly low, making it a sound investment, especially if you are a professional. In many cases, you will be able to find a combination unit that you can use for welding as well.

This process involves creating an electrical beam of heated electronically ionized gas to complete an electric circuit through the material that you are cutting. The circuit is completed back to the unit itself by making use of a ground clamp. Depending on the material that you want to cut, the plasma is created by compressing gasses like oxygen, inert, air and more and blowing it through a concentrated nozzle.

As the plasma cutter blows the concentrated gasses to the metal surface, an electrical arc forms within the gas, connecting an electrode near the gas with the metal that you are cutting.

As the electrical arc ionizes the gas, plasma forms, which in turn delivers and focuses intense heat on the work object, causing it to melt. Because you blow this matter at a high velocity towards the work object, it blows the molten metal away and divides the piece. This process allows for making neat, angular, or curved cuts.

Plasma Cutting Process

What are consumables, and how do they ensure a neat and successful cut? A typical plasma cutter system makes use of five different consumables: the shield, retaining cap, swirls ring, nozzle, and electrode.

The shield’s job is to protect the rest of the consumables against molten metal and sparks. If you don’t have a lot of experience with these machines, opt for a  drag shield.

The retaining cap holds the consumable stack together, and the nozzle focuses the plasma arc. The size of the nozzle orifice is significant in constricting and focusing the arc. For fine cuts, a small orifice is better.

The electrode conducts the current from the torch to the plate and completes the electric circuit. It typically is a copper piece that contains hafnium or tungsten.

The swirl ring guides the gas in different directions from the machine and down the torch. This consumable is key to prevent burning the nozzle.

Generally speaking, the length of the duty cycle depends on how high the amperage rating is. The duty cycle refers to the plasma cutter’s ability to perform under a specific load for a period of time. To ensure that you buy a high-performing model, look at the average thickness that it can cut.

A solid unit will be able to make a ¼” cut. If this is the width that you will be able to cut, pushing for more can have a compromising effect on precision and the neatness of the separation.

A lower duty cycle means optimal performance for a limited duration. After this time period, performance levels may drop, and your project will take longer. For heavy-duty projects, a duty cycle of 50% – 60% will be sufficient.

When looking at the different specifications, it is important to prioritize the duty cycle as this can play a significant role during operation.

Plasma Cutter

When shopping for cheap plasma cutters, there are some things that you have to take into consideration. Knowing the requirements of a high-end product can help you get a reduced buying price as well as lower running costs.

Electrical Considerations

Before buying, make sure that your workshop has 110v or 220v outlets. You should also ensure that your breakers have sufficient amps to withstand the amperage of the unit and the compressors.


This consideration depends on your unique needs. If you plan on cutting regular metal sheets, a unit with a cutting thickness of ½” will be sufficient.

Other Considerations

Keep in mind that you want the most optimal duty cycle for your projects. Don’t spend too much on a plasma cutter that has the performance to spare, but don’t limit yourself in terms of future project needs.

Also, make sure that you will be able to use consumable economically to keep your running costs as low as possible. Low-quality models tend to deplete consumables at a faster rate.


Operation in different locations is sometimes necessary, especially if you are a professional. This means that mobility is a must-have feature that you are looking for in a plasma torch. There are some aspects that influence the portability of a unit.

The most important aspect is weight. For some people, 35 pounds may not be manageable, but for others it is. Make sure that the unit is not too heavy for you.

Built-in carrying features like handles or shoulder straps can also increase portability. Power output is another aspect that can diminish your ability to use the system in different locations and settings.

To ensure that you get the best value for money, it is important that you shop in the right place. We found that Amazon is the best place to search for a plasma cutter. There are many reasons for this.

In the first place, there is complete transparency. You can see exactly what buyers and existing owners think of the products through reviews, recommendations, and tips. Secondly, the cost of switching sellers is zero. You don’t have to spend time driving around store to store to find the best product at the lowest price.

If you don’t like what you see, you can simply click away. You also get access to an abundance of information and specifications for each model of plasma cutter on this platform, which makes comparing models with one another much easier. You can also choose from more units.

Finally, Amazon’s own customer service is excellent. If you buy from a prime seller, you will have your new plasma cutter within a day or two.

One of the biggest considerations when shopping for equipment is the price. The average cost of a plasma cutter unit on sale can range from $475 – $800. Although the price is not necessarily an indication of the product quality, you can expect to pay more for plasma cutters on the high end of the quality spectrum.

If you are a novice in metal construction, try to opt for durability and versatility instead of heavy-duty performance. This may help you to find a product that is suitable to your needs without you having to break the bank. It will also ensure that you get the best possible value for money.

For the casual welder, less expensive torches will get the job done on occasion. As a weekend DIY metal worker, it can be beneficial to go for more affordable models. You will be able to find a high-end design that, although limited in terms of thickness and speed, will provide you with quality cuts and a long lifespan.

Even if you have the means to buy a costlier model, it may be better to stick to a higher quality but affordable machine rather than overspending on something that you don’t need.

If you are a professional steelworker, you may have to pay more for industrial plasma cutters with longer duty cycles and bigger power outputs. This is especially important if you are in the business of mass production.

Although more affordable units don’t necessarily have compromised quality, chances are that you will see a reduced ability to perform high-speed and thicker cuts. If you need a plasma cutter for everyday use, you may not be able to get away with lower-priced systems.

Before buying a plasma cutter, it is important for you to be as informed as possible. You also have to make sure that you know exactly how you will use the plasma cutter. Take the cutting widths you want to make, types of metal you will be cutting, as well as regularity of use into account. Use reviews and tips to be sure you have the right model for you.

Additionally, you should also make sure that you get all the consumables and welding gear that you may need. The rate of consumable use is significant as it determines your machine’s running costs over time. It can also influence your initial costs to buy the unit.
