How to Choose the Best Plasma Cutter on a Budget

There is a wealth of plasma cutters on the market at various price ranges. A larger variety means more to choose from for the average tradesman. However, if you’re not a tradesman or are just getting into the craft, this variety can prove to be a bane rather than a boon.

Getting a cheap plasma cutter will only be beneficial if the cutter fulfills your requirements and serves you well. Similarly, a more expensive cutter could be a huge waste of money if your requirements can be fulfilled by a more affordable alternative. We have crafted this concise but useful guide for first-time buyers. Taking the following factors into consideration, you can ensure that you buy only the right product for your needs.

Consider Your Budget

Apart from the performance considerations that we will go over below, this is probably the most important consideration when you are out looking for a plasma cutter. The market, as we mentioned, is filled to the brim with plasma cutters.

You’ll see cutters from some familiar power-tool manufacturers, and you will see some lesser-known names on the shelf as well. When you’re out shopping, it is easy to get carried away and stretch your budget or go over it if you see some truly exceptional hardware.

However, consider your requirements, then practically consider if you need a powerful and expensive plasma cutter. If you are just starting out, the chances are that you don’t need the most expensive cutter. Talk to experienced users and get expert advice on the amount of power you need for your tasks and spend accordingly.

Duty Cycle

This is an important factor that you need to consider for the plasma cutters that fall in your budget. The duty cycle is the measure of how long the device can function during a single session. If you will be undertaking tasks that require the use of the plasma cutter frequently but not continuously, consider the machine’s duty cycle. A machine with a lower amperage output will have a smaller duty cycle, and one with a higher output will have a longer duty cycle. This information is always present in the specifications of the particular plasma cutter that you are considering.

If you will be using the plasma cutter less frequently but for a longer period in a single session, then consider the machine’s maximum amperage output rather than the duty cycle. The more powerful a machine is, the thicker it will cut. For reference, a 30 Amp plasma cutter will produce clean cuts up to 0.38 inches; a 50 Amp cutter can go up to 0.5 inches.


This is another important consideration as it affects both performance and safety. If you are a new user, take some time to go over and understand this particular factor; overlook it at your own expense. All power cutters, regardless of their price, require a good amount of electricity to function.

If the device does not get the required amount of electricity from the power source, it won’t function. If it continues to demand more power than the source can provide, it can end up burning its internals and even the power source. To prevent this from happening, match the machine’s power requirement with the available power source.

Smaller machines that require a power input of 110V to 120V can be used with most indoor power sources. These devices are suitable for light usage by homeowners and DIYers for light repairs. More powerful machines that require a 220V power source should only be connected to generators. Dual-voltage cutters can be used with both power sources.

Speed and Thickness

While the thickness a plasma cutter can cut is determined by the amperage, how efficiently its cuts is determined by the speed. This is why we will be considering both these factors together. When purchasing a cutter, determine the thickness you will be cutting, then consider the maximum thickness at which the machine can deliver a fine cut.

The speed of the plasma cutter will determine the quality rating it comes with. This rating is often mentioned in the specifications. We’ll go over each of the three cut ratings so you know what they mean. Match these to your requirements, and you will have a cutter that serves you well.

Rated Cut

This is the finest cut rating, suitable for projects that require a certain level of finesse. Plasma cutters with this rating provide a fine cut at a fast speed, but can only cut through mild steels and thinner metal.

Quality Cut

This is a balanced rating. Cutters with this rating deliver a good quality cut on thicker metals. They do tend to take a bit longer though.

Sever Cut

Plasma cutters with this rating are the slowest, so expect your tasks to take longer. However, they cut deeper than other machines and are suitable for use on thicker metals. The deeper a machine cuts, the less refined the quality of the cut is.


We hope that this guide has made you more aware of the factors you need to consider in order to purchase the right plasma cutter. We find that the Lotos LTP5000D is the best plasma cutter under 500 dollars. It has proven itself time and again with its clean cut and its consistent performance. However, do keep in mind the considerations mentioned above to make your purchase in line with your needs.
