Things to Consider

In this guide, we will give you more information that you’d need before and at the point of purchase. We will discuss the benefits of these devices, what you expect from models of under $300 price range, and also give you some criteria to consider while purchasing.

How does a plasma cutter work?

10 Quality Plasma Cutters under $300 – An Affordable Solution for Tough JobsThe plasma cutter has the following structure: a power source, a stable handpiece, a ground cable and a power supply, a compressed air supply and electrodes.

The device is connected to the power source by an electric cable. The connection to the device and a clamp for the material are usually attached to the earth cable.

The ignition process creates an electrically conductive gas – the plasma. Because of this type of generation, a plasma cutter has a temperature of 30,000 degrees celsius on the plasma. This is the only way to burn conductive metals with pinpoint accuracy.

Before the cutting process begins, you must first place the cathode on the material. Then the circuit is short-circuited.

With the help of the compressed air, the nozzles of the plasma cutter can rise slightly, creating an arc. The plasma cutter can now ignite and the cutting current increases. From now on, the plasma cutter begins to penetrate the material.

Tip: The material can be easily processed and cut using an electric arc.

The plasma cutters usually do not have an integrated compressor but the connections for it. For the plasma cutter, the compressed air must be fed in from an external compressor. If this is not possible for you, you should look for a plasma cutter with a compressor.

The eponymous plasma is the gas. Plasma is sometimes called the fourth state of matter (next to solid, gaseous and liquid). For example, in pure nature, lightning is a good example of plasma. Lightning is also just a discharge of electrical voltage through a gas.

Plasma is also a conductive gas, which means that it can conduct electricity. The arc is mostly kindled by ignition and tied through a nozzle made of copper.

In the arc itself, a jet of plasma is then formed from the compressed air gases. This causes the respective object to melt, but the energy of the beam immediately pushes the liquefied component of the object out of the cut area again.

Benefits of having a plasma cutter

10 Quality Plasma Cutters under $300 – An Affordable Solution for Tough JobsThere are numerous advantages of a plasma cutter over other cutting devices. Plasma cutters are mainly used in industry.

These special cutting devices cut metal and other hard and electrically conductive materials with a thickness of up to 40 millimeters. A plasma cutter has the advantage over other cutting tools such as laser cutters because it has a very high cutting quality.

A plasma cutter is essential for processing electrically conductive metals. It works so precisely and cleanly that post-processing of the workpiece is hardly necessary and efficient work is possible.

Plasma cutters are also known as plasma torches because they work with a hot gas that can reach temperatures of up to 30,000 degrees when cutting.

Pros of plasma cutters

  • Cutting with low heat input
  • Cutting electrically conductive materials
  • Cutting steel and aluminum in great thickness
  • High cutting speed
  • Good automation
  • Low noise level when cutting wet

Cons of plasma cutters

  • More expensive than autogenous cutting systems
  • Restriction in the material thickness
  • Relatively wide kerf
  • High power consumption
  • Noise from dry cutting

Plasma cutters under $300: What to expect?

The models in the under $300 range weigh around 22 pounds on average. They are easy to transport and usually come with a power source, an earth cable, a power supply, a compressed air supply, and electrodes.

You connect the plasma cutter to a power source via the electrical cable. The connection to the device and a clamp for the material are usually located on the earth cable.

The electrically conductive plasma is created during the ignition process. With a heat of up to 30,000 degrees, the plasma cutter can precisely process metal.

However, for models within the indicated price range, the cutting thickness on metal doesn’t usually go past 15 millimeters. For example, the hynade HYC-50D and the Mophorn CUT-50F have a thickness capacity of 14 millimeters. However, the more premium ones can easily reach 40 millimeters.

Features to consider before you buy a plasma cutter

To ensure that the plasma torch fulfills the purpose for which it is intended, the following points should be compared for the various models that interest you.

Purchase criteria such as the cutting thickness, the material, power consumption, possible uses, voltage, compressor connection, and the built-in technologies should play a role when buying. In the following, we explain what these aspects are all about and which model fits which needs, and which power connection.


10 Quality Plasma Cutters under $300 – An Affordable Solution for Tough JobsThere are two main categories of plasma cutters on the market:

  • Transmitting plasma cutter
  • Non-transmitting plasma cutter

Also, plasma torches can be divided into:

  • Hand-held plasma cutter
  • Machine-guided plasma cutter
  1. Transmitting Plasma Cutter: This type of plasma cutter is the most widely used. It transfers the pilot arc to the conductive materials through the gas flow. This process ignites the main arc. A transferring plasma cutter only processes electrically conductive materials. The cut quality is very high.
  2. Non-Transmitting Plasma Cutter: This type of cutter works on a wide variety of materials, including concrete or glass. The non-transmitting plasma cutter is characterized by the fact that a constant arc burns between the electrode and the nozzle. The nozzle delivers the hot plasma that melts the material when it is touched by the arc.
  3. Hand-held plasma cutter: Hand-held plasma cutters are well suited for rough work. They are often used on construction sites, for example, to break down coarse waste. A hand-held plasma cutter is light in weight but less powerful than a machine-operated device.
  4. Machine-operated plasma cutter: A machine-operated plasma cutter cuts very thick materials. The operating costs are comparatively low for the simple models. The disadvantage of machine-operated plasma torches is their high weight, which makes them unsuitable for transport and flexible use.


The mains voltage is the voltage with which a plasma cutter works. Most devices have an output of 110/220 volt. Others have up to 400 volts. A high voltage connection is required to work with 400 volts.

Plasma torches with an output of over 400 volts are more suitable for professionals. For DIY enthusiasts, a device with a voltage of around 220 volts like the PrimeWeld CUT50D is sufficient.

Cutting ability

10 Quality Plasma Cutters under $300 – An Affordable Solution for Tough JobsThe cutting thickness determines the cutting ability. The cutting ability of the plasma cutter depends on the type

and thickness of the material that the device is to process. The device requires more power for cutting steel than for processing sheet metal.

The cutting thickness of a plasma torch indicates the maximum thickness of the material to be cut. Devices with very high performance have a cutting thickness of 35 to 40 millimeters. On average, and for models under $300, plasma cutters can make around 15 to 20-millimeter cuts.

Due to the high operating temperature and the ability to process conductive metals with pinpoint accuracy, the plasma cutter is used in many areas of daily life. First and foremost, in the metal processing industry, but also in the field of rescue services, the plasma torch is indispensable today.

Classic areas of application are:

  • The metal processing industry.
  • Emergency services and civil protection

Rescuing the seriously injured, also with the help of hydraulic tongs and prying devices, often requires a plasma cutter to cut through body parts quickly and without any further risk of injury to the casualty.

But plasma cutting devices are also enjoying increasing popularity in the private sphere. The reasons for this are of course the falling prices for entry-level models in recent years and the many advantages that a plasma cutter has to offer in direct comparison with a so-called Flex.

Whether for the hobby workshop or various work in the garden, on the farm or during renovation. If conductive metals are to be processed with pinpoint accuracy and low accident rate, a plasma cutting device also offers numerous advantages in the private environment.

Duty cycle and cutting current

10 Quality Plasma Cutters under $300 – An Affordable Solution for Tough JobsFor the range of devices we looked into, 60 percent duty cycle is the best a device can have within this price range, and you can find this in the PrimeWeld CUT50D. Cutting current is basically the strength of the current, which in turn is used to cut. In this respect, you can assume that the cutting current tells you roughly how much current you need to cut the object you want.

Also, you can assume that every plasma cutter has something like an area in which it is specified how high the respective cutting current is. In this interval, it is then possible to set how high the cutting current should be. This means that the higher the cutting current is set, the higher your cutting strength.

Compression connection

The compressor is needed because it has to supply your plasma torch with enough compressed air for the entire duration of your work. What is meant by a compressor connection? This question is easy to answer, because the compressor is simply the part that can compress a gas (e.g. air).

Air is also the gas that is most commonly used in plasma cutters. Actually, the compressor does nothing more than compress the air in order to then output it again with increased pressure.

It should also be noted that there are plasma cutters with integrated compressors. However, most types of plasma torches do not have built-in compressors, so they require an external air supply.

Plasma cutters that have a compressor built in are often more expensive than devices that do not have an integrated compressor, even if you save yourself the search for a compressor and don’t have to lug it around.

However, keep in mind that this rarely affects the performance of the plasma cutter.

Power consumption

Some models use far more electricity than others. So that the plasma cutter does not turn out to be a power hog, a comparison of the average energy values ​​of the various devices should be made before buying.

Dimensions and weight

Will the plasma cutter always be used in the same place or rather flexibly? If it is to stay in place and there is no transport, the weight does not matter. With flexible use, how many pounds the device weighs should play a bigger role.

The most lightweight models like the Mophorn CUT-50F can weigh between 10 to 12 pounds while the models intended to be used in a fixed position, further adding to the built-in technology and features, can weigh as much as 25 to 30 lbs.

Additional accessories may be necessary, which are included in the scope of delivery in the best case. Regardless of where the plasma cutter is used, protective goggles and gloves are always necessary for protection. And you have to note that these will contribute to the weight.


The warranty is an assurance of the reliability and durability of the device. With plasma cutters within the under $300 price range, some brands don’t offer warranty coverage. But it is best to pick a model that has coverage. The ideal warranty coverage is between two to five years. As a reference, the PrimeWeld CUT50D comes with three years of warranty.

Other important features

10 Quality Plasma Cutters under $300 – An Affordable Solution for Tough JobsSome of the extra features to watch out for include the:

Input current

The input current is the highest level of current that your plasma torch can draw. The input current is measured in amperes (A) and, depending on the device, is a maximum of 20 to 40 A.


The airflow shows you the following: it shows you how many liters of air must be consumed by your plasma cutter in one minute. How much airflow your plasma cutter needs is of particular importance when purchasing a particular compressor.


The frequency describes the level of activity with which your plasma cutter works. There are plasma cutters that work with a high frequency and plasma cutters that work with a lower frequency. The frequency is measured in Hertz. Special ignition devices use a voltage of up to 10 kHz (kilograms of hearts).

The igniters that work at such a high frequency are used to ignite the pilot arc. However, you should make sure that there are no computers, laptops, or other high-quality electrical appliances nearby. Because if you ignite the pilot arc, the use of the high frequency can seriously affect these devices.


Your plasma cutter should be equipped with the so-called inverter technology as best as possible. The inverter is the part of your plasma cutter that is responsible for converting direct current into alternating current. This happens because the plasma cutter absolutely needs direct alternating voltage to generate the arc.


Yes, you do. There are plasma cutters with and without an integrated compressor. A compressor supplies the plasma torch with compressed air during cutting. If the device does not have a compressor in the package, a separate air pressure compressor must be purchased. The manufacturer’s information on the respective plasma cutter provides information on the power required by this compressor.

Yes, a plasma cutter uses gas known as compressed air. The plasma cutter is a cutting device that operates when a gas is supplied with so much energy that a large number of electrons leave the atomic shell. This results in positively charged ions surrounded by free electrons. This ionized gas is electrically conductive. This, thus, makes it possible for the device to cut through any metal that is conductive electrically.

Most plasma cutters can cut through copper, carbon steel, iron, aluminum, and stainless steel.
