Keep reading to find out all of the advantages and disadvantages of CNC plasma cutting so that you can make the best decision for your business.

Advantages of plasma cutting machines

Utmost precision

Due to the plasma arc, plasma cutting machines offer the utmost precision, which makes them ideal for cutting intricate shapes. In fact, they can be guided with the same level of precision as drawing a line with a pencil.

High speed

Plasma cutters are able to cut very quickly, making them one of the most productive and efficient cutting methods. These fast process times also mean that there is less risk of metal abrasion and cutting errors.


Plasma cutting can be used on a wide variety of metals, including to cut steel, iron, copper and alloys due to the power of the pilot arc. Furthermore, they provide a high quality cut edge every time.

Computer controlled

If you are looking to maximise productivity, you should know that plasma cutting machines can be computer controlled. This means that you do not need as many workers to operate them and that you can continue to work outside of your current operational hours.

Cost effective

Plasma cutting equipment is widely recognised as great value for money. Plus, plasma torches rarely require maintenance, so you will not need to spend money on replacement parts.

Disadvantages of plasma cutting machines

Can only cut through materials of about 1 inch

While a plasma cutter can cut through pretty much any metal that conducts electricity, in terms of thickness, it can only accommodate around 1 inch.

The cutting process is noisy

Although you are probably used to a little, or a lot, of noise in your workshop, you should know that plasma cutters tend to be loud. Plus, generate a lot of fumes, so you need to make sure your workspace is well ventilated.

Eye protection is needed

The electrical arc creates very bright flashes during the cutting process, so you need to make sure that every one of your workers are supplied with protective goggles and offered safety training.
