Plasma cutters are tools that are used in metal work to cut through metal of various thicknesses. They can cut through metal plates, bolts, pipes as well as metal sheets. Additionally, they make excellent tools for removing defective welds and for back-gouging weld joints. To accomplish this, plasma cutters use “plasma” i.e. superheated electrically ionized gas. This gas is produced by passing an electric current through a stream of inert gases which are propelled at a high velocity. The electrical current ionizes the molecules of these gases thus creating a jet of hot plasma that can slice through metal.
Plasma cutters are a superior option to hacksaws and other torches mainly because they don’t throw off as much metal fragments and debris during cutting. Instead, they provide cleaner cuts with much less debris. The cuts are also more precise. With plasma cutters it is much easier to create intricate shapes and textures in a variety of other materials apart from metal due to the greater precision of the cuts. For contractors working with thin metal, the plasma cutter can be used to cut out stencils along finely drawn lines or create templates without producing excessive heat like some torches do that warps the metal.
As you can deduce from the above intro a plasma cutter is an invaluable tool to have in your workspace especially if you deal with metal. You’ll save tremendous time and spend less energy in your activities.

Choosing the Right Model
There are many benefits to owning your own plasma cutter. Whether you enjoy working with metal as a hobby or you deal exclusively with metals in your job, owning your personal plasma cutter will accord you great convenience, lower your cutting costs and ultimately save you time as well.
If you’re a fan of oxyfuel cutting and are just learning about plasma cutting technology you should know that plasma cutting trumps oxyfuel cutting as far as speed and efficiency are concerned.
Plasma Cutting vs. Oxyfuel Cutting Differences?
A plasma cutter projects a jet of ionized gas in a high velocity from a constricted orifice. This ionized gas, which is simply known as plasma, conducts the electricity from the cutter’s torch projecting it to the work piece a.k.a metal causing instant severing of the bonds of the metal thus causing the material to melt. This results in a cut. A plasma cutter can be used on a wide variety of metals due to the very high temperatures that are produced through this method which does not rely on oxidation or burning.
Oxyfuel cutting, on the other hand, cuts metal through oxidation or burning. The downside of this technique is that some metals tend to form oxides in the process of cutting that render the method ineffective inhibiting further oxidation from the torch. Aluminum and Steel are examples of such metals. In this regard plasma cutting is much faster and more efficient.
The plasma cutter industry is continually evolving. More and more manufacturers are joining the market at a rapid rate and flooding it with their own cutter inventions and models; each boasting unique specifications and abilities, with the intention of grabbing the customers’ attention. With so many options available and increasing by the day the process of choosing a plasma cutter has become more complex than ever before. As a customer, you cannot afford to be complacent when it comes to selecting a cutter as this might work out against you in the short or long term depending on the model that you choose.
Here are a few tips (and questions you should ask yourself) to help you find the best model for you. The tips are random and not organized in hierarchy of importance.
Here are a few tips (and questions you should ask yourself) to help you find the best model for you. The tips are random and not organized in hierarchy of importance.
Size of The Metal
One criterion that is used to distinguish plasma cutters is the size/thickness of the metals that they are built to cut through. This is indicated in the description of all plasma cutters so be sure to look for it before making a purchase. Most plasma cutters have a thickness cutting range of between ¼” and ½”. The Super Deal Plasma Cutter 50 Amp CUT-50 Digital Inverter, for instance, can slice metal to a maximum of 1/2″. To determine the best cutter to purchase start by asking yourself what is the size of metal that you will be working on frequently. If you’ll be cutting a lot of ½” thick pieces then seriously consider buying a model that is built to cut through a slightly higher level of thickness. Purchasing one that has the exact specifications that you need may occasionally make poor cuts especially as it ages.
Power
In some instances the level of thickness may not be listed on a product but instead you may notice amps have been mentioned. The amps of a plasma cutter are directly related to the ability of that cutter to sever metal. That is, the higher the amps, the greater the thickness it can cut through. Typically, a machine that has 25 amps can slice through a ¼” metal while one that has between 50-60 amps is engineered to cut ½” metal. Additionally, a machine rated 80 amps can cut anywhere between ¾” and 1” of metal.
What Environment Will You Be Working In?
The type of environment that you will be working in- particularly if you use the machine on a day to day basis- plays a huge role in its effectiveness and the duration that it can serve you. If you plan on using it in an environment that is shared by other metal workers and is sure to be filled with metal shaving (from the excessive grinding) and dust then it is advisable to choose a machine that incorporates Fan-On-Demand™ or Wind Tunnel Technology™. A good example of this is the Hobart 500565 Airforce 27i Plasma Cutter. The technology will work to the machine’s protection to prevent any grinding dust from settling on the critical components of the cutter. The fan turns on only when the presence of dirt particles is detected in the cutter’s chamber. This technology makes the units more efficient than the traditional units with a fan that run constantly – consuming energy unnecessarily.
What’s The Cutting Speed You Prefer?
Speed is critical if you plan on using the cutter for your job activities that involves metal work. Speed can make a huge difference in the time it takes to complete a project and subsequently the amount that is earned. As you’ve probably noticed in the plasma cutter reviews above, cutters come in different amperes. We’ve already established that amperes influence the cutting capability of these machines but what you might not know is that the number of amperes also determines, to a great extent, the cutting speed. A good rule of thumb when choosing a cutter that can function at a faster speed is to buy one that exceeds the requirements of the metal that you plan to work on. For example, if you plan on using the cutter on ½” metal sheets then buy a cutter that can is designed for 3/4″ or 1″ jobs. While it is true that a machine with the exact specifications as that of your metal will work perfectly fine there is no guarantee that its speed will exceed that of a machine built for denser material.
Duty Cycle
If you’ve found plasma cutter reviews with the term “duty cycle” and you don’t know what that means, it’s simply a term used to denote the period a plasma cutter can be used continuously before it overheats and requires cooling. Normally, duty cycle is expressed in percentage form over a 10 minute span. For example, if a cutter is rated as having a 70% duty cycle at 50 amperes then it means that 50 amperes of current can be used continuously for 7 minutes out of 10 minutes before the machine requires rest. From this we can deduce that the higher the duty cycle associated with a particular plasma cutter the longer the duration it serves. If you’re a professional craftsman who deals with metal you need to factor in the duty cycle as this will affect the duration to complete certain projects which will in turn affect your level of income and productivity. Hobbyists can also consider the duty cycle if they prefer working on their projects with minimal downtime.
Consumables
Assuming you’ve already decided on a plasma cutter, one of the ongoing expenses you will incur as you use the cutter will be for consumables. Consumables involve electrodes, cutting tips, the shield, nozzle, retaining cap e.t.c. These parts often require frequent replacement or swapping as time goes on to enhance the performance of the cutter. The cost of consumables for plasma cutters varies from model to model and from brand to brand. The expenses incurred in some models over a given period of time may be more or less compared to other models based on the number of consumables that are present. If you’re looking for a cutter that is cheap to maintain then it is advisable to pick one that has a small number of consumables. This translates to more cost savings due to fewer parts that require replacement.
Other Equipment
In addition to consumables, you may also need to base your decision on other equipment that comes with the cutter. This refers to accessories such as gloves, eye shields, shoulder strap, e.t.c The greater the number of accessories that come packaged with the welder the more money you stand to save since you don’t have to buy these related items separately. When considering the accessories, it is important to also factor in the price of the plasma cutter. Sometimes it may be economical to buy a low priced cutter and buy the accessories separately than to purchase a cutter that is overpriced just to benefit from a few extra add-ons. Do due diligence to ensure you’re able to make the right choice based on the circumstances.
Desiccant Air Dryer & Filtration Systems
A desiccant air dryer in a plasma cutter is not an absolute essential but it ranks highly among the things to consider in a cutter before making a purchase. Its purpose is to remove water vapor and other hydrocarbons in the cutter that might interfere with the process of ionizing the compressed air. This results in more powerful plasma that can cut through metal with greater ease than a cutter without one.
Additionally, these dryers help to preserve the cutter. Moisture inside the system causes damage in subtle ways that chip away at the efficiency of the device and raise the maintenance costs. By eliminating the moisture the user is guaranteed to lower the operating costs significantly.
A good filtration system should be considered to keep away oil and other dirt particles from invading the innate chamber of the cutter and interfering with its functionality.
If you’re a user who is working in a plant where you have to constantly move around with your plasma cutter from site to site then portability is a factor that you should keep in mind when making your purchase decision. In such a case, look for a cutter that is lightweight such as the Lotos LTP5000D 50 Amp Plasma Cutter that weighs 26 pounds which you can use a shoulder strap with, or you can choose a heavier model that can function on a valet style undercarriage for enhanced movement.
Safety
Last but not least, always prioritize safety in any cutter that you buy. Plasma cutters require considerably high voltage to form the plasma. Sometimes this can be as high as 300 volts. Most machines come with a nozzle that safeguards the user from potential hazards of such high voltage. If a particular cutter does not have a nozzle as part of its package it paves room for serious accidents to occur. To be safe, purchase only welding machines that have a safety nozzle that prevents the welding arc from starting unless the nozzle is properly positioned in its place. And dont forget to follow health and safety standards; No protective welding gloves means no welding work!
Handheld Plasma Cutting
Most of the tips offered above also apply to handheld plasma cutters. That said; there are a few points users should keep in mind when performing handheld plasma cutting. These have to do with safety.
- Always wear a pair of gloves and eye shades to protect your eyes from the plasma arc. One of the best eye covers is a grade 5 green color shade. It offers protection similar to that of a welding mask but with more visibility.
- Use a quality face mask to protect yourself from the nasty fumes that will envelope your face as you go about welding. This is especially important when cutting stainless steel which produces toxic fumes. One of the gases – Chromium -has been linked to sinus, nasal and lung cancer among other cancers.
- Although many plasma cutting machines have fume extraction systems, never fully rely on this protection but instead take the aforementioned precautions to guarantee your safety. It is also important to master the proper cutting, gouging and piercing techniques to avoid any potential safety risks.
Conclusion
When searching for a plasma cutter don’t forget to inquire about the product warranty of a given model and the seller’s return policy. Some companies tend to overstate the functionality of their plasma cutters in a bid to boost sales. A good return policy will ensure that you are adequately compensated in case the unit you purchase does not live up to its marketing.
The above aforementioned plasma cutters are highly sufficient for most tasks in the home that require light metal cutting. Those that are specialized for denser metals/materials have been pointed out in the pros section. The main difference between these cutters rests in the design and performance. Take some time to go over the reviews to make an informed choice. Whichever option(s) you choose you are guaranteed a very positive experience.
Editor Notes:
Do I need a mask when using a plasma cutter?
Generally, you’ll need to have protective gear for safety. A normal mask isn’t a priority instead you can get a welding mask for good protection. Note that the cutting arcs are intense and can lead to blindness if not managed.
Where can I use a plasma cutter?
In most cases, the plasma cutters are used to cut metal and will be ideal for construction companies, automotive repair, and other large-scale projects.
How does a plasma cutting machine work?
The plasma cutter uses electricity and will send an electric arc through a gas going through a constricted opening which squeezes it at a high speed. The high speed enables the gas to cut through the metal with ease. Ensure you have the correct settings on your computer for accurate cuts.
What materials can plasma cut?
Materials that conduct electricity are good for plasma cutting. This means the cutter will not work well with plastic and wood material hence the need to avoid such materials.
What amount of air will a plasma cutter need?
This depends on the type of cutter you have, the thickness of the materials you are cutting, and the overall speeds of cutting the materials. You can get the best guidelines from the manufacturer’s manual in the package for the correct air requirements.
