Buying Guide: Features to Consider in the Best Plasma Cutter Under $500

Duty Cycle

This term is very specific to plasma cutters and similar machines, so it’s understandable that some individuals may not be entirely aware of its meaning. With that being said, it represents how long a plasma cutter can be active without shutting itself down to cool down. Typically, it’s measured in percentage.

If you’re using the cutter for a very short period of time, then a high percentage of the duty cycle may not be a make-it-or-break-it factor. But generally, it’s preferred to look for plasma cutters, which have longer duty cycles. That means that you can operate longer with it before it needs to cool down. Models with higher amperage typically are known to provide longer duty cycles.

For professional purposes, a duty cycle of around fifty percent is deemed sufficient. If you need a plasma cutter for home usage, then something around thirty or thirty-five percent can do the work just fine.

What’s more, your budget, as well as the task you have to execute, can be important factors to consider when it comes to this feature, too.

Density of Metal

Not every plasma cutter can effortlessly cut every type of metal. You can’t expect a model for beginners to cut through a metal that’s half an inch thick. That’s why it’s important to match the metal you’re working on with the model you’re looking for.

In fact, a plasma cutter’s amperage can influence its ability to cut through dense metals. To illustrate, a plasma cutter that has twenty-five amps can easily go through metal with a thickness of a quarter of an inch. Double that and a fifty-amp model can easily cut half an inch of metal. Further, a model with eighty amps can be considered sufficient for metals with a density of even an inch.

Source of Power

Before setting on buying one particular model, you should be familiar with the cutter’s power source or the voltage on which it operates.

As a standard, it’s considered that the majority of homes have outlets of 110/220 Volts. These plasma cutters tend to be less expensive and a bit limited when compared to others in their performance. Moreover, these models aren’t essentially suitable for going through a quarter of an inch or half an inch gauge plate.

On the other hand, a plasma cutter with a power input of 220/240 Volts is capable of cutting through denser materials without any trouble.

Having said that, some machines have a dual voltage system. That means that they can work on both 110/220V and 220/240V depending on the power source you can provide. And if you need more power for a specific task, you can get it. These models are known for being versatile and easily adjustable, too.


This is always a nice characteristic to find, especially in a device that not everyone is skilled and experienced to use such as a plasma cutter. For starters, all models have an easily recognizable power switch or some other way of managing the power-related settings.

Additionally, models should have labels on the buttons and indicators so that users know what does what and what each is for. Some brands even go as far as putting LED indicators on the panel so that the signals are easier to read. However, be prepared to pay a bit more for these models that come with all of these small yet important details.


To come up with a cutting arc, a plasma cutter utilizes electricity. This cutting arc is often measured in amps. The model’s amperage is another feature that should be matched with the metal thickness that should be effortlessly cut through. For instance, twenty amps are frequently found and are very practical for cutting an eighth of an inch of metal. What’s more, the more amps the model can muster, the faster the cutting will be.


It isn’t seldom for users to travel around for a welding job. Not all of them are static. So, when you switching between welding sites, it’d be cool to easily transport your plasma cutter. That’s why portability is an important feature that many users factor in their decision.

Subsequently, the size as well as the weight can seriously determine how portable and compact the plasma cutter will be. Naturally, a smaller cutter that isn’t bulky can be packed in a couple of minutes and won’t weigh you down.

Another thing is the ruggedness of the design. If you plan to weld on the go, then this characteristic is desirable to have. It will protect the cutter and make it more durable.

While you’re transporting the cutter, you’ll need a suitable case. So, make sure that your portable cutter has a hard case for carrying it around that won’t damage it while you’re moving.

Cutting Speed

We briefly mentioned cutting speed before. Even though it may not seem like something you should pay attention to at first glance, sometimes it can be included in the making of the final decision.

For example, imagine two plasma cutters and both can successfully and effortlessly cut through half an inch of metal. The first one does it in a minute, whereas the other one you’re finished in four to five minutes. It doesn’t take much knowledge in plasma cutters to figure out that the latter plasma cutter would be a better investment.

What’s more, cutting speed is influenced by your workflow as well as your present welding needs.

Frequently Asked Questions (FAQs) Regarding the Best Plasma Cutter Under 500 Dollars

What can I use my plasma cutter for?

Answer: There is no limitation to what a quality plasma cutter can do. Beginning with its utilization around the home. Many users operate with them when they’re creating DIY crafts as well as in their workshops at home as a type of hobby. But the cutter’s original usage is far wider than home-usage. It spreads to industrial purposes, automotive cutting, professional artwork cuts, and similar.

Do I need other equipment and gear with plasma cutters?

That way you protect yourself from sparks, debris and dangerous other particles that may be a byproduct of the cutting.

What can a plasma cutter cut through?

Answer: The first thing when someone mentions a plasma cutter is a metal. That’s actually the short answer to the question. However, there’s a reason why a plasma cutter is used for cutting through a variety of metals like copper, stainless steel, aluminum, and such. Moreover, these materials are electrically conductive. And plasma cutters are utilized for precisely these types of material. That’s why you can’t cut through plastic or wood with a plasma cutter. Simply, they aren’t electrically conductive.

What are some tips for handling plasma cutters?

Answer: The most basic thing you should watch out for is reading the manual. It consists of all the necessary data regarding the cutter you’ve purchased. So, if you have any questions, they’ll most likely be answered by it. Then, make sure you’re using the right amperage settings that match the case outlined before you. Otherwise, you may end up messing things up and damaging the cutter. Also, you should keep an adequate distance between your body and the actual area where the cutting happens. This is a dangerous process and that’s why you should at all times wear protective gear like gloves, boots, eye protection, and more. What’s more, even testing the cutter can inflict damage if it isn’t handled properly. So, even before you start testing, you should have a general idea of the machine and how it works.
