What is plasma cutting?

Plasma cutting is a process that cuts through metal by using a combination of plasma and forced air. It works by electrically charging the air to an extremely high temperature. This ionizes the air to create a channel of plasma that, with the help of compressed oxygen, blasts the plasma through a focused nozzle at high speeds to cut the material.

To put it simply: the metal is heated to molten temperatures and then blown away with air.

Plasma cutting is becoming the preferred method of cutting because of its ease of use, low consumable costs and ability to produce clean cuts. If you’re serious about metalworking then you’ll need the best plasma cutter available.

How to Choose the Best Plasma Cutter?

Advantages

Wide Range of Materials and Thickness

When it comes to cutting metal nothing compares to the power and convenience of a plasma cutter. From stainless steel to aluminum the best plasma cutter can cut through almost anything less than an inch thick. It’s one of the only methods where you can make non-linear cuts with ease. Because of the wide range of materials that it can cut it is the preferred method if you want clean cuts done quickly.

High Cutting Speeds

Plasma cutting is by far the fastest way to cut metal which is why it is the go-to method for fast-paced production. Typically the higher the amperage the quicker and cleaner the cut, the more work you can get done. While speed isn’t so important to a hobbyist it’s still a factor that needs to be considered. Speed is measured in inches per minute (IPM) and is noted on the plasma cutter itself. A general rule of thumb to maximize productivity is to choose a unit that that can handle close to twice your normal cutting thickness. That way you’ll be able to slide through like a butter.

Compared to oxy-fuel or mechanical cutting, plasma cutting is like a Ferrari to a used Prius. If speed is a priority, plasma is the way to go.

Easy to Learn

Despite its seemingly complex process, plasma cutting is just as easy to learn as MIG welding. You just aim the torch, press the button and move it. Of course it’s a bit more complicated then that, but not by much:

Step 1 – Hold the torch above the metal by about 1/8 inch.

Step 2 – Press the trigger.

Step 3 – Once the arc starts cutting, slowly move the torch in the direction of the cut.

Step 4 – Adjust your speed so you see sparks going through the bottom.

Step 5 – At the end, angle the torch slightly towards the edge before finally severing it.

Low-cost Consumables

With plasma cutting the only gas you’ll ever need is air so the cost after the initial purchase is minimal.

You will however have to replace parts on the torch on a semi-regular basis. The shield, retaining cap, nozzle, electrode and swirl ring all need to be replaced eventually. Fortunately the shield protects almost everything so out of all that the shield is the only real cost for consumables, and even that doesn’t have to be replaced too often. Compared to other processes like MIG or TIG, plasma cutting is practically free. If you want to know more about consumable cost check out this article from The Fabricator.

Plenty of Accessories

Cuts often have to be done to exact specification which can be difficult if you’re just eyeing it up and trying to hold steady. Luckily there are a ton of accessories and tips to make the process a little bit easier.

Beveled Cut – Cutting to a specific angle is impossible without the use of a guide. Don’t even try, you’ll just mess it up.

Straight Cut – While possible without accessories, you’ll get a much nice cut if you use a roller to keep you on a straight path. If you but the roller up against something, you’ll get a perfectly straight cut each and every time.

Circle Cut – Forget trying to cut a circle without help. This tip is similar to the other two but it has only 1 wheel to guide it. The other part is firmly planted in the center of the circle to give you a nice clean cut.

No Preheating

Preheating is a process that is used to prevent the metal from cracking when welding or cutting. Fortunately unlike oxy-fuel you don’t have to waste time preheating the metal, making it a much quicker process. All you have to do is point and shoot and watch as the torch pierces through the metal. Furthermore, plasma cutting has a smaller heat-affected zone which prevents the metal from warping and damaging the surrounding area. This makes it the ideal method for cleanly cutting thin gauge metals with precision.

Minimal Clean Up

Besides some burrs and slag on the edges of the metal plasma cutting is a surprising clean process. Unlike oxy-fuel or mechanical cutting which gives off fumes and dust and forces metal chips everywhere, plasma cutting is much nicer. The metal is liquefied then blasted to the ground making clean up later a breeze. Just grab a broom and you’re done.

Relatively Safe

If done correctly plasma cutting is the most efficient cutting method available today.  If you wear the required safety gear and are properly trained, plasma cutting can be done safely and effectively.

That’s not to say their aren’t hazards but I’ll cover those below.

Non-linear cuts

If you need to do some non-linear cutting then the best plasma cutter is what you need. Because of the narrow kerf you are able to make cuts in whatever shape necessary. If you need any type of precision cutting done, plasma is the way to go.

Disadvantages

Expensive Start-up Costs

While owning and maintaining the best plasma cutter itself isn’t expensive, the initial cost of the machine is. A basic low-end plasma cutter from an unknown brand will cost you at least $250. Then you have to deal with all the issues that come from such a low-quality complicated machine: dealing with customer service, having to send parts half way around the world, constant breakdowns.

On the other side of things you have the high-end plasma cutters. These will run you anywhere from $800 to $3000 and beyond but will last you for years and years without issue.

If you invest just a little more money upfront you’ll save yourself a ton of headaches and money down the road.

Limited Cutting Thickness

Plasma cutting is by far the most efficient way to cut metal and for most hobbyists it will suffice. But what if you need to cut a thick piece of metal?

Unfortunately for anything more than 1 inch thick a plasma cutter just wont cut it.

For that you need either an oxy-fuel torch or a mechanical blade.

Safety Risks

As with anything that deals with fire and electricity there are plenty of inherent safety risks.

A few things to consider when determining the risk factor:

  • Toxic fumes
  • Arc burns
  • Eye and skin protection
  • Electrical shock
  • Proper grounding
  • Noise

If you take the proper precautions and observe the correct practices and wear all the required PPE (welding helmet, gloves, jacket, etc.) you’ll be fine.

What Will you be Cutting?

To avoid buying an unnecessarily overpowered or a machine that isn’t up to the task it’s critical that you know what you will be cutting beforehand. The last thing you want is to drop $1000 on the best plasma cutter only to find out it wont cut what you need.

Therefore one of the first things you need to consider is the thickness and type of metal you most often cut. Plasma cutting power sources are rated on their cutting ability and amperage so if you only need to cut 1/4″ thick metal then a machine with 25 amps is plenty. If you need to cut 1/2″ thick material then aim for a machine with higher amperage – around 50 – 60. For metal around 1/2″ – 1″ thick you need a rig with at least 80 amps.

While a smaller machine has the ability to cut through thicker materials, the cut will often be severed and low-quality. Generally you want a machine that falls within your budget with the maximum power output. See the chart below:

Plasma Cutting Chart

What you Need to Consider

Power

The most important factor you need to consider when buying the best plasma cutter is power output. Too low amperage and you wont make the cut, too powerful and you’ve just spent a bunch of money you didn’t need. Know your needs beforehand and it will save you time and money down the road.

Output – The single most important factor for selecting a plasma cutter is power output. Consumer cutters range from 10 – 80 amps and even higher if you count CNC machines. Higher amperage means you can cut thicker materials quickly. So if you have the money, by all means, go all out and get the most powerful one available. But if you’re like me, on a limited budget, then see the chart above for amperage to thickness ratio to avoid paying for something you don’t need.

Input – Now that you’ve figure out how much power you’ll need for cutting, you’ll need to figure out how much power it takes to run the machine. If you’re a hobbyists you’ll likely have 115 V running throughout your home and for most people that will be enough. You can run a 25 amp plasma cutter without having to upgrade. If you plan on getting something bigger than 25 amps you’ll need to upgrade your power supply to 230 V. That’s not to say a more powerful machine wont run on 115 V, but you wont get the maximum power output.

Duty Cycle

Another important factor is the length of duty cycle. The duty cycle refers to the amount of time you can operate the machine in a 10-minute window before having to take a break. For example: a plasma cutter with a duty cycle of 30% @ 45 A means you can work for 3 minutes at 45 amps before having to rest the machine for 7 minutes. This prevents overheating so you don’t accidentally turn your expensive tool into an expensive door stop.

The best plasma cutter will have a long duty cycle so you can keep working without having to take a break to twiddle your thumbs for 5 minutes.

Cutting Speeds

Plasma cutting is known for its speed and precision which is why it’s quickly overtaking other methods when it comes to production work where speed is key. While speed isn’t so important for hobbyists it’s still something to consider. You don’t want to spend all day with a cutting torch. Cutting speed is directly related to amperage and material thickness. High amperage on thin material will be sliced through like paper while low amperage on thick material will barely engrave the metal.

If speed is important to you, refer to the cutting speed chart above to help make your decision.

Material Thickness

You’ve already determined how thick of materials you’ll be cutting so I wont spend much time here. Just keep this in mind when making the decision:

< 1/4″ = < 25 amps

1/4″ – 1/2″ = 50 – 60 amps

1/2″ – 1″ = ~ 80 amps

Torch Type

Every plasma cutter will come with a standard torch but there are times when you need a specialty torch or tip. Torches are also the first consumable to break down so having an extra on hand is never a bad idea.

Look for a torch that includes a drag shield. This helps to keep a steady distance between the metal and the torch to give you a nicely uniform cut. It also helps protect the rest of the torch. I mentioned tips above but it’s important to note that not all torches are tip adaptable. If you think you might need tips eventually, make sure the torch is compatible.

Air Supply

Plasma cutting consists of two basic elements, fire and air. Fire to heat up the metal and air to blow it away.

Usually you have to supply your own air by means of an external air compressor. If you don’t already have one this can be an extra expense that’s not really necessary. The best plasma cutter will have a built-in air compressor so it’s one less expense to worry about. Today there are many options available if you don’t already have a compressor including the top rated Hobart Airforce 12ci.

A built-in air compressor is a necessity if you need to lug the machine around from job site to job site.

Starting Method

There are two main methods for starting the arc with a plasma cutter: high frequency and contact. Both have their advantages and disadvantages but the best plasma cutter will have the option for both.

High-frequency – This method works by creating such high voltage between the electrode and the metal that the arc jumps from the torch to the work piece without physical contact. This is the most common starting method but also the most dangerous in terms of electrical hazards. Furthermore high frequency can interfere with nearby computers or other electrical equipment causing irreparable damage. As a result, this method is not preferred.

Contact – Contact starting is exactly what it sounds like. The torch features a DC+ nozzle with a DC- electrode inside which are physically touching. To start the pilot arc you need to pull the trigger which forces the nozzle and electrode apart. You then lower the pilot arc close to the work piece where it establishes the cutting arc. It sounds complicated but all you need to know is this: pull the trigger to start the arc. Because there is no electrical ‘noise’ contact starting is the preferred starting method and is found mainly on high-end machines.

Portability

These days most plasma cutters are extremely light with convenient handles to make carrying it around a breeze. Look for a unit that’s less than 50 pounds, ideally less than 30, and you’ll have cutting power wherever you go.

The best plasma cutter, while more expensive, will have a built-in inverter to help generate power thus drastically reducing its size and weight.

Internal Cooling System

If there is no proper cooling system your plasma cutter will overheat quickly, costing you time and money and rendering your new cutter useless. That’s why it’s critical to get a machine with a robust cooling system with fail-safes to shut down if it’s not cooling properly.

Most consumer plasma cutters use forced air to cool down the torch. This is fine for machines up to 100 amps but when you get into the high-end commercial CNC plasma cutters special coolant is required.

Without a quality cooling system you’ll have to replace consumables at a much higher rate.

Extra Features

Try to look for a machine with as many extras as will fit your budget. Extras make your life easier and your work better. Many brands have their own patented systems with fancy names but it’s important to remember they all do pretty much the same thing.

Safety start sensor – With this feature the plasma cutter will not start unless the nozzle is in place.

Long pre-flow sequence – This allows for advanced warning before the arc starts so you can safely get out of the way.

Continuous output control – Automatically adjust the power output when cutting uneven surfaces so you don’t have apply constant precision pressure to the trigger. This helps to reduce hand fatigue.

Multi-voltage plug – Higher amperage plasma cutters use both 115v and 230v input so having an easily adaptable plug is ideal for switching back and forth.

Quick release torch – Different jobs require different torches. A quick release torch will save you time and money if you need to constantly change torches.

Warranty

Finally the best plasma cutter will have an outstanding warranty. The last thing you want is to have your machine break after a year only to find out the warranty is only good for 6 months and wont cover your issue anyway. It’s critical to read the warranty beforehand, especially if you’re buying a Chinese import brand.

Fortunately the big 3, Miller, Lincoln and Hobart, all stand by their products by first producing high-quality equipment and second by offering amazing warranties.

It’s reassuring to know that after you’ve spent a small fortune on a plasma cutter the company will stand behind it if anything goes wrong.

Plasma VS Oxy-Fuel Cutting

Cutting is an important process for many welding related jobs. The two main methods for cutting metal are plasma arc and oxy-fuel. Both have their pros and cons depending on the situation so it’s critical you know which tool is right for each job.

Plasma

How does plasma cutting work?

Plasma is created by ionization,  adding energy (electricity) to an electrically neutral gas (air). These elements are combined in the torch between an electrode and nozzle. This causes the gas to become unstable and thus creating plasma. Air is then forced through the tip of the nozzle at incredible speeds of up to 20,000 feet per second. For reference, a bullet shot from a handgun travels at about 2500 feet per second. As the metal heats up to molten levels by means of the electrically charged air, the air simultaneously blasts through the work piece creating a clean, smooth cut.

Pros:

  • Cuts non-ferrous metals
  • Speed and precision
  • Smooth cuts
  • No preheat
  • Cuts thin metal without warp
  • Make non-linear cuts

Cons:

  • Can only cut up to 1 inch thick
  • Limited portability
  • High start-up cost

Oxy-Fuel

How does oxy-fuel cutting work?

Oxy-fuel cutting begins by preheating the steel with a fuel gas flame to its ignition temperature. An extremely high-powered jet of oxygen is then directed at the steel. This creates a chemical reaction between the oxygen and the metal to form iron oxide or slag. The jet of oxygen blasts the slag away from the kerf allowing you to cut much thicker metals.

There are four main fuel gases: acetylene, propane, propylene and natural gas. Each one has different properties so it’s important to know which gas to use for each job. To select the right gas you should consider what you are cutting, cost, heat output and oxygen consumption.

Pros:

  • Cut up to 20 inch thick metal
  • Greater portability
  • Versatility – able to cut, weld, braze, bend etc.
  • Longer torches to keep a distance
  • Low cost

Cons:

  • Can only cut ferrous metals
  • Warps thin metal
  • Slow
  • Grinding required after

When determining which tool to use you need to ask yourself two questions:

  • What am I cutting on a regular basis?
  • How thick is the metal?

If you are cutting metals thicker than 1 inch on a regular basis oxy-fuel cutting is the go-to method. It saves you time and money in the long run by being able to quickly slice through the material. If, on the other hand, you are precision cutting stainless steel or aluminum, plasma cutting is preferred because of its narrow kerf and the fact that it wont warp the metal.

Tips for Choosing the Best Plasma Cutter

Do your Research

Ranging from $500 – $3500 a best plasma cutter will likely be one of the most expensive tools in your arsenal so you need to do proper research before committing.

Consider Buying Used

Scour Craigslist to find some amazing deals on plasma cutters. Often times people will buy a plasma cutter only to realize they don’t use it as often as they thought they would. This is a great opportunity to pick up a lightly used machine for a much lower cost.

Warning: If you are new and don’t really know what to look for, I’d advise you to either buy new or bring a friend along who can tell you if you’re getting ripped off or not.

Rent Beforehand

Because buying a plasma cutter is such an expensive purchase, if possible, you should try to test the one you want beforehand.

If you’re buying used ask whoever you’re buying it from to see first, if it works and second, if it will work for your needs. If you plan to buy new, most cities will have a place where you can rent tools by the day. Call them up and rent one for an afternoon to see if you like it.

The last thing you need is to buy a plasma cutter that isn’t suitable for the jobs you need it to perform.

Choose Quality over Cost

This one might be hard to justify if you’re on a strict budget but buying a cheap plasma cutter will only cost you in the long run. From repairs to low quality consumables to low duty cycles a cheap machine will not only cost you money but valuable time as well.

That’s why it’s critical that you spend as much as you can within your budget to get the best plasma cutter for the money. A good quality plasma cutter will run you at least $800 but if you are saving money in the long run, it’s worth it.

What Features to Look Before Buying

best plasma cutter for home use

Size

There are several types of cutting machines that are separately available both online and in the store. You will find small compact units that can be used for household purposes. They can be moved from point to point easily, as they are light.

Heavy-duty units are designed primarily for garages and commercial applications. These large units require a table with wheels or trucks so that it can be easily transported from one location to another. It is essential to buy the size of the machine that is going to meet your demands.

Consumables

When deciding which brand of plasma cutting machines you should buy, you should consider the parts that should be replaced for the life of the device.

Some manufacturers have more difficult to get parts than others. You have to discover a machine that has fewer parts to replace; this will cost you less money when it comes to maintenance costs for the device. Consumable parts contain things, such as a cathode or the tip of the burner.

Warranty

Warranty is an integral part of any quality hardware brand. You need to make sure that the warranty of the machine you are buying is not less than two years. Why? This is fundamental because these cutting devices can be highly expensive to repair.

Likewise, make sure to run with a brand that has been on the market for a while. A widely known brand implies easy access to its consumables.

Output Power

plasma cutter voltage output

The plasma cutter output power determines the thickness of metal it can cut. If the output power is high, thicker metals can be cut easily and quickly. It is essential to select the units indicated by the type of metals to be cut.

Duty Cycle

It is also important to consider the duty cycle of the unit before settling on a given brand. The duty cycle of the plasma cutter shows the highest performance of the unit.

Small devices take less time and power to work, while large jobs require high-end metal cutters.

Input Power

It is also essential to determine the total power required by the unit to cut metals. The thickness of the metal determines the amount of power needed for the machine. Leaner metals take less time and energy than the thicker metals.

Cutting Speed

The cutting speed of the unit is also another critical factor that must be considered before you obtain these cutting machines. The speed of the cutter is usually recorded as IPM or inches per minute. It’s imperative to choose machines with the right cutting speed for it to be profitable and comfortable to work with.

Types of Torch

plasma cutter torch types

There are for the most part two types of cutting torches used in the plasma cutter. The two assortments contain the burner with high recursion and the contact starter burner.

High-frequency cutting torch is reliable and safe. The Contact Start Torch is very useful as it instantly turns on.

Inverter Technology

All metal cutters do not accompany inverters, but those who by chance come with one accompanies a hefty sticker price. The inverter takes the direct current and passes it through a high-frequency transistor inverter ranging from 10 kHz to 200 kHz.

Voltage

Machines operating on 110/220 V power outlets are similarly less expensive and have limited applications. But those Plasma cutters at 220 / 240V are expensive and cut through thicker materials.

Voltage input determines the thickness of the metal, which can be cut easily with that given cutter.

Amperage

Plasma cutters make use of electric currents to create the cutting arc that is estimated up to the current level. Customers need to match the amps next to the thickness of the metal they want to cut and the source of the power they will use.

It is important to note that the current has a positive connection with the cutting speed. A plasma cutter that has more amperage offers a higher duty cycle that can meet your requirements if you want to work for longer periods of time.

Metal Thickness

25 amps will make the trickle metal 1/4 inch thick, while 50 amps will be needed to cut through ½ inch metals, and 80 amps can cut through 3/4 to 1 inch thick metals without lifting a finger barely.

Controls and Indicators

All plasma systems require a circuit breaker and another method of changing the current setting, depending on the type of metal being cut.

The current controller even has LED indicators on the front of the board, making it easy to read the inputs, even though they may cost more.

Casing

If you need to use your cutter indoor, then it must be well cased for safety. The safer housing units may cost more than the less safe units. But for the people working outside, the extra cost is worth it as still there are other elements not required to get in contact with the cutter.

Frequently Asked Questions

As it seems typical for any wide-minded person after reading such material to have a series of questions, below we cover some of the most asked questions by our users and readers.

Q. What are the differences between industrial and non-industrial plasma machines?

Non-Industrial Plasma

Industrial Plasma

Cheap unit

Expensive unit

Soft work

Heavy work

  • Q. Whys are industrial plasmas costly when compared to their counterpart; the non-industrial plasma?

As in most cases, we associate the value with the price, it is not different in this situation. Low prices imply that low productivity, reliability, and performance. Also, you can avoid common plasma cutting problems by avoiding lower budget machines.

  • Q. Is plasma cutting safer than welding?

The plasma cutting process can be very safe. By observing safety standards and correctly setting up and operating the system, plasma cutting is no more of a hazard than most welding processes.

  • Q. Why should I choose a plasma cutting machine and not OXY cutting machine?

Plasma cutting machines offer more possibilities than oxy-fuel cutting technology. With one of these machines, you experience high-quality cuts and higher speeds.

  • Q. In which cases should I consider a laser cutter over a plasma cutter?

When high precision is required. They are used in areas where you need high accuracy. For example, in case you want to cut a finely detailed saw blade.

These machines not only provide precision, but you can rely on them to do repeated cuts with the same high precision.

  • Q. How is the plasma cutting process?

Plasma cutting is a method of cutting metals that uses a sharp velocity beam of ionized gas usually produced from a narrow, restricting orifice to strike the metal.

The high-velocity ionizing gas or plasma, as is known, while it strikes the metal conducts electricity from the plasma cutter’s torch to the piece that is to be cut. The plasma heats the material, in this case, the metal to melt.

Then the molten metal is blown away mechanically by the high velocity ionized gas.

  • Q. What is the difference between plasma cutting and oxyfuel?

The simple fact is that plasma can be used for any conductive metal – be it mild steel, aluminum or stainless steel. As for oxyfuel, it will burn through oxidation, or in plain language, burn the metal that cuts it.

  • Q. I am getting problem cutting thick material, how can I go about?

A well-known secret for thicker materials is to turn the torch slightly to increase the orientation of the torch rather than pulling the angle as you cut through the last part of the material.

A critical instruction is never to finish a cut by flicking the last edge of the work with the torch.

Wrapping Up

For those considering purchasing a plasma system, it is essential to be aware of the performance of the system and whether this unit can meet all the requirements, and not just a single part of it.

It is also vital to ensure the efficiency of the machine before buying these cutters. The above ten machines are what most customers have reviewed, according to their performance and value. Buy one from the above best plasma cutters and come back with positive feedback. Cheers!
