5 Best Cheap Plasma Cutters That You Can Buy in 2021

Crafting things at home isn’t just about cutting paper, making leaflets or woodcraft, since sometimes you’ll have to work with much more heavy-duty materials, especially if the thing you’re working on is supposedly something durable.

Cheap Plasma Cutter

For example, although it may sound complicated at first, welding is also something that the average user can do by themselves, although having a plasma cutter can indeed come in handy.

Unfortunately, for all of their usefulness, plasma cutters tend to be on the expensive side, so if you’re on a tight budget, making sure that you benefit from the best cost-performance ratio suddenly becomes a priority, and that’s when you need a budget-friendly plasma cutter.

However, the Internet is vast, and even a product that may not seem so sought like a plasma cutter can still be found under hundreds of labels and thousands of model names, and this makes choosing the right one for you rather difficult.

Best cheap plasma cutter featured

Because of that, we’ve decided to do the grunt work for you and compiled a list of the best plasma cutters on the market today that can be deemed as being very budget-friendly, while still maintaining high-performance standards to get the job done right.

How Much Does a Plasma Cutter Cost?

The main reason you’re reading this article is probably that you’re looking for a plasma cutter and the price tag is your main criteria.

Well, a quick Internet browse will show you that a plasma cutter can cost anywhere between $250 and $1500, but of course, the prices can go even higher, but that’s purely the case with industrial cutters.

Presuming that you are a regular person that just wants to do some welding and metal cutting around the house, we advise that you go for plasma cutters that are durable, versatile, and have low maintenance and consumable costs.

Sure enough, you can opt for a plasma cutter with a lot of cutting power that is pricier, but if you’re only ever going to use it at its full potential just once (if ever), then that would be financial overkill.

That being the case, the products that we will be showcasing aren’t necessarily the cheapest, but rather the plasma cutters with the best price/performance ratio.

Where Can I Buy an Affordable Plasma Cutter?

Amazon

Whenever you’re considering buying a new product, plasma cutter or otherwise, the first place you should always look for is the manufacturer’s official website. Not only do they have the best prices (third party sellers will usually add a fee of their own), but their customer support is sometimes quicker to respond.

However, if you’re interested in the real-life specs of a machine, there’s no better place to buy a machine (especially a costly one like a plasma cutter) than Amazon.

Not only do you get to see the honest reviews of potentially thousands of users, but Amazon also features the occasional sales that can sometimes be bigger than on the manufacturer’s own website.

Besides, Amazon brings the added benefit of having thousands of products that you can compare, whereas a single manufacturer will have just a handful of products that are usually similar in both specs and prices.

The last reason to go ahead and consider buying from Amazon is that you don’t have to wait for too long in order for the product to be shipped to your home.

Sellers that are marked as Prime Sellers benefit from better delivery times and, depending on where you are, you may even get your product within a couple of days.

Expensive vs. Budget Plasma Cutters

This little debate is solely based on how you plan to use the plasma cutter once you buy it. You see, if you’re only ever going to be welding once in a while, a more affordable model will do just as good of a job as a more expensive one.

Sure, they won’t be able to cut just as deep, and the cutting speeds themselves will be lower, but at least the end results will be precise, and the machine will still last for a very long time.

Besides, what’s the use of buying a more powerful and expensive model (even if you have the money to spare) if you never even plan on using it to its full capacity?

However, those of you that do this for a living, such as professional steelworkers will greatly benefit from having a far more powerful plasma cutter, one that has a higher duty cycle ratio and a greater power output.

Sure enough, the initial investment will be high, but considering that the plasma cutter is the tool that brings you the money ( steelwork is incredibly profitable), your initial investment will be returned in no time at all.

However, unlike other types of products where lower prices are usually correlated with reduced quality, things are different with plasma cutters. While they don’t necessarily break easier or do a shoddy job, they just take longer to accomplish the same feats as their more affordable counterparts.

What Is Plasma Cutting?

Plasma cutting

If you’re looking for a budget-friendly plasma cutter, chances are that this may well be your very first plasma cutter (who would want to invest a lot in a machine they have little experience with?).

As such, we would like to start off by showcasing what exactly is plasma cutting, so that you can understand by these machines can be so useful, and why they tend to be so expensive in general.

Plasma cutting is the process of creating a jet of hot plasma as a means to cut through electrically conductive materials (usually metals).

This process is usually used when dealing with electrically conductive materials like:

  • Stainless steel
  • Aluminum
  • Copper
  • Brass
  • Steel, etc

Plasma cutting is usually used in fabrication shops, repairing and restoration vehicles, construction work, and other activities heavily industrialized activities where enormous quantities of metal may be involved.

However, since you don’t actually need any certification to use a plasma cutter (just protective equipment and common sense), the average user can take up this activity in their day to day life, as it can be incredibly useful around the house.

Because of this, if you like repairing and restoring things such as your own house or car, knowing how to plasma cut can be incredibly useful.

Besides, while the initial investment may be a bit large (unless you choose to follow the entries in this article, of course), operating a plasma cutter, as well as the consumables, can be very cost-effective, so those of you that will be using it consistently will see a return-on-investment in no time at all.

How Does Plasma Cutting Work?

The basic principle behind plasma cutting is creating a beam of superheated electrically ionized gas (a.k.a. plasma). The plasma is generated by the plasma cutter, and it is generated through the material that you are working with.

This process forms a complete electrical circuit back to the plasma cutter via a grounding clamp.

The gas itself is compressed and blown out through a nozzle aimed at the material that you will be cutting. Speaking of gas, the one that is used in plasma cutting can be one of many, with some gases being optimized for cutting certain materials:

  • Oxygen
  • Air
  • Inert, etc

An electrical arc is then formed within the gas between an electrode and the working material itself (that’s why the process only works on electrically conductive materials). The electrical arc’s purpose is to ionize some of the gas, which finally leads to the creation of the electrically conductive channel of plasma.

This jet of superheated plasma not only creates enough heat to melt your target material but the pressure from the high-velocity plasma and compressed gas blow the hot molten metal away, which helps with separating (cutting) the two melted pieces.

Besides, because the blown gas creates a very hot and very localized cutting cone, plasma cutting is ideal when you need to cut sheet metal in curved or angled shapes.

Plasma cutting diagram

Here’s how plasma cutting works step-by-step:

  1. An initial spark ionizes the gas inside the torch head.
    • This makes the gas to be conductive which in turn allows the initial arc to form.
  2. The initial arc then forms inside the torch head.
  3. The plasma’s current then flows from the electrode to the nozzle within the torch head.
    • The initial arc burns up the nozzle during this phase.
  4. The plasma is then blown out of the nozzle towards the working material due to the compressed gas.
    • This provides a current path from the electrode to the working material.
  5. When the plasma cutter’s control system senses current flowing between the electrode and the working material, it will cut the electrical connection to the nozzle.
  6. Current then travels from the electrode to the working material allowing the arc to form inside the nozzle.
  7. You can then start cutting without fearing that you will burn up the nozzle.

Note: Because of how this process works, the life of the nozzle is not dictated by the cutting time, but rather by the number of arc starts, therefore rendering nozzles consumables.

What Consumables Are Needed in Plasma Cutters

Speaking of consumables, before you go ahead and buy yourself a plasma cutter, you need to remember that other investments will be involved as well, not just the plasma cutter itself.

You see, in order to obtain an efficient and safe cut, there are certain consumables that you will need to use on a regular basis, so make sure that you have plenty before starting a cutting job.

Torch Body

The torch body is to be the working end of the plasma cutting system, serving the following purposes:

  • It’s the source of pre-flow, plasma gas, and shield gas for the other consumables
  • This is the piece that delivers the cutting current to the electrode
  • Fixates the other consumable parts in perfect alignment

Electrode

The electrode is probably the most noticeable consumable in a plasma cutter, as it is probably known even by people that have never even used a plasma cutter before themselves.

The main function of the electrode is to provide power to the plasma arc, acting as both the starting point and electrical contact point of the plasma arc. Typical electrodes are usually made of tungsten or hafnium, due to the material’s high melting point.

Nozzle

Due to the nozzle’s perfectly round orifice and the sharp inner and outer edges, it allows the plasma to flow in a way that will create cuts that are both sharp and precise.

As mentioned earlier, the nozzle’s lifespan is dictated by the number of arc starts, but it can also be affected by incompatibilities between the other consumables since they need to be a perfect match.

Note: In order to ensure the best cut quality, we recommend that every time you change the nozzle, you change the electrode as well.

Swirl Ring

The purpose of the swirl ring is to control the swirling movements of the plasma as it is blown out of the nozzle around the electrode, and acts as a key component that prevents the plasma to burn the nozzle after the initial arc start.

One way to increase the lifespan of not only the swirl ring but also the nozzle and the electrode is to make sure that the swirl holes are not clogged with dirt or other debris.

Note: With proper maintenance, swirl rings can even last through several electrode and nozzle changes.

Shield

Just as its name leads you to believe, the shield’s main purpose is to protect the other components of the plasma cutter, along with other features:

  • Increases cutting quality and allows for faster cutting speeds
  • It protects the nozzle from molten splatter material
  • It enables drag-cutting when using a hand torch
  • It allows the nozzle to keep cool

What to Look for in a Plasma Cutter

plasma cutter criteria

Now that you know how plasma cutting works and what materials you will have to use and replace over time, it’s time to talk about the actual specs that you will need to focus on when looking to buy a brand-new plasma cutter.

Duty Cycle

A plasma cutter’s duty cycle should be the first thing that you look at when browsing to buy on, as it is the criteria that has the most impact on how the cutter will perform.

When talking about plasma cutters, the duty cycle is its ability to work at a specified capacity for a set amount of time, and it is usually dictated by the device’s amperage rating and is usually displayed as a fraction or as a percentage.

The duty cycle in turn is directly correlated with the plasma cutter’s ability to cut sheet metal of a specific thickness, with higher duty cycle ratios allowing you to cut through thicker and thicker materials.

The process of plasma cutting can be used on materials of a variety of thicknesses, although the exact limit is dictated by the plasma cutter’s power. For example, small handheld plasma cutters can cut a 38 mm (1.5 in) thick steel plate, while the much stronger computer-controlled torches can cut steel up to 150 mm (6 in) thick.

Plasma cutters with a lower duty cycle provide optimal performance for a limited duration, after which performance levels start to drop, meaning that the cutting will take longer to finish.

For those of you that are mostly interested in heavy-duty projects, look for devices that have a listed duty cycle of around 50% – 60%, as they will be more than enough.

For the purpose of this article, the average plasma cutters you should look for should be able to handle cuts that are at least a quarter-inch thick. Sure enough, they can be used on much thicker materials, but the precision of the cut will be compromised.

Electrical Input and Output

Since plasma cutters can be dangerous, it’s wise that you only use and store them in designated spaces, usually crafting rooms. However, before you go ahead and buy the plasma cutter itself, make sure that your room is equipped with proper power outlets that will meet its needs (110V or 220V outlets will suffice).

More so, make sure that the circuit breakers in your crafting room can withstand the amperage of both the plasma cutters and the compressors.

Cutting Thickness

While it is true that you won’t always be cutting the same sheets of metal over and over, you probably know already what types of materials you will be working with most of the time.

That being said, the next criteria you should take into consideration when buying a new plasma cutter is the cutting thickness, so if you only ever plan on cutting through very thin materials, you can go ahead and go for the least powerful ones on the market.

Weight

If you’re a professional that does metal cutting for a living, a part of your job will involve travelling between work sites, which in turn means that you’ll be carrying the plasma cutter with you everywhere.

That being the case, compact size and reduced weight can be really helpful, so if you have no way of actually seeing the plasma torch to gauge its size and weight, pay very close attention to the product’s specs and reviews since you don’t want to buy a product that will cost you your back in just a few month’s time.

Costs

Since your main concern is how much does a plasma cutter cost, other criteria that you will need to pay attention to is the price. However, we are not talking about choosing the cheapest product around, since that would be easy, but rather the most cost-efficient product that fits your needs.

On one hand, there’s no need to pay too much on a high-performance plasma cutter if you’re only looking to do one job with it and then store it in the shed and let the dust settle on it.

On the other hand, if you plan on using the plasma cutter regularly, keep in mind that cheaper models tend to burn through the consumables a lot faster, turning your initially cheap investment into a costly one in the long run.

Best Cheap Plasma Cutters: Closing Thoughts

Now that you know what plasma cutting is, what it involves, and what you need to look for in a plasma cutter, we hope that you can make a much more informed decision when you decide to make your next big purchase.

However, keep in mind that there is no precise standard, and the choice is entirely up to you, as the best tool for the job depends entirely on what you need it for.

That being said, before you go ahead and spend money (even budget-friendly plasma cutters cost several hundred dollars), make sure you plan ahead and know exactly what kind of cuts you’re planning to make, what materials you will be using, and how thick they will be.

Besides, we recommend that you not only look at the pros of a product but also at the cons as well, especially when it comes to issues that deal with a plasma cutter’s performance.

Lastly, take into account that plasma cutters need consumables as well, so don’t go running off and buying the cheapest machine you see, since you might end up paying more in the long run.

All in all, the products that we’ve included on our list were chosen so that they met the needs of a wide variety of users, and that is why one of our entries isn’t exactly budget-friendly but showcases incredible cutting prowess.

Let us know if there’s any other plasma cutter that you think deserves a top spot on our list, we’ll review it, and then we will update the article accordingly.
