What is a Plasma Cutter?

First, let’s look in a little more detail at precisely what a plasma cutter is and how it works. Essentially, plasma is the fourth form of matter (with solid, liquid and gas being the other three) and can be created by applying electricity to a gas. This is precisely what happens in a plasma cutter where an electric arc is applied to the gas in order to excite the gas particles and make them electrically conductive.

Depending on the unit you use, your plasma cutter will use oxygen, nitrogen or even environmental air as the gas and force this inside the torch. Meanwhile, electricity is generated from an external power supply and applied to the high pressure flow of gas. This creates a ‘plasma jet’ which has an incredibly high temperature up to 40,000 degrees F! This makes short work of most materials and allows for a very clean cut.

Types Of Plasma Cutter

Industrial vs Light Duty - One is for hobbyists who work on DIY projects and the other type is for professionals who need to produce precision cuts in less time and need more power and deeper cuts.

Manual and Automated - Automated plasma cutters are used with a CNC machine. If you go for automated plasma cutter, ensure that it doesn’t use a high frequency circuit as it can erase the stored configurations.

Now we’ll look into some of the best plasma cutters with built in compressors on the market and describe how to ensure you’re getting a good instrument to add to your tool box.

5. Hobart 500564 Airforce 12i Plasma Cutter

Finally, we have the Hobart 500564 Airforce, which is priced very similarly to the Forney and has similar specs on paper. This device is once again a plasma cutter with built in compressor and has some smart design features such as a smaller heat-affected zone to prevent warping. It also lets you use a no gas pressure mode for tuning the flame and ultimately allows you to achieve a more exact cut with a thinner kerf and less slag and mess to clean up after.

Weight wise, the Airforce comes in slap bang in the middle at 31 pounds – which is pretty light and portable all things considered. It also has very similar requirements and performance in terms of power. It is recommended for cutting 1/8 inch steel and goes up to ¼ inch. It also has a built in inverter power supply.

Pros

  • Built in air compressor
  • 20 Amp circuit, most powerful in its segment
  • Extra consumables
  • Post-flow air cooling
  • Lightweight and portable
  • LED indicators for pressure/temperature readings

Cons

  • Although 20A circuit is powerful, generally houses have a 15A circuit.

6. Forney 317 Plasma Cutter 115FI with Built-In Compressor, 120-Volt

Next up with have the Forney 317 Plasma Cutter. This device comes in several flavors but the one we’re looking at here is the most comparable unit at 120V. Again, it’s a portable but powerful device which is what has earned it its place in the top spot here alongside the Air Cut.

Looking at the specs, this device weighs in a little heavier at 38.9 pounds – something to consider if you intend on using it a lot by hand. The cord is also shorter at 7 foot – though this will be fine for most uses. This cutter once again runs on 15 amps and is similarly powerful. Portability is enhanced by the in built inverter power supply.

The product describes the recommended cut as 1/8th thickness though says it can ‘severe ¼’’’. One quarter is larger than three sixteenths (the maximum capability of the Air Cut), however it’s worth noting that the wording suggests that perhaps the performance suffers at these higher thicknesses. Suffice to say that the performance between these two is comparable and it’s not immediately obvious which comes out on top! What we also get here is the cut speeds which are 20 inches per minute.​

There are also some additional perks to this device. ‘Drag torch’ technology for example means that the torch can be dragged directly across metal surfaces for precise cuts and it also has thermal overload protection and smart heat management.

Of course if you’re looking for a little more power then you can upgrade to the 230V option which has dual inputs and a removable torch and ground cable. This has a greater maximum thickness but of course this is reflected in both the price and the weight. There’s also a lower powered option for more portability.

What might clinch it for some readers though is that the Forney is somewhat cheaper at 120V than the Air Cut.​

However, both have their pros and cons and both will make a great tool for cutting metals. Customer reviews are again largely positive but limited.

Pros

  • Drag cutting technology makes cut more precise
  • Built in compressor
  • Might be good for beginners

Cons

  • Slower than others in terms of cutting speed
  • Higher weight than other products in this segment

7. Thermal Arc 1-1110-1 Air Cut 15C Plasma System

This is a portable, light and powerful little performer. At just 29 pounds and with a convenient handle, you can easily bring this with you on a job and it won’t take up too much space in the van. What’s more is that it also offers a lot of cutting power and great cutting speed as well.

The recommended cut for this device is 3 millimeters or 1/8’’. However, the maximum capability is 5 millimeters or 3/16 inches. This runs on 120 volts with a 15 amp plug as standard. The company (Thermadyne) claims that this gives the device a 25% edge over the competition in terms of performance (these things are always rather hard to quantify but it certainly sounds good on paper).

There are a couple more thoughtful features here too, which also put the product in a good position. For starters, the cord is an impressive 20 foot long, which is very handy for a range of different applications. The trigger is easily accessible when gripping the torch and the device claims to be suitable for rust and paint as well.

With all this in mind, you have here a very capable plasma torch that should be suitable for all hobbyist uses and most commercial applications. It packs a lot of punch for its small size and is generally a well thought out product – though you do pay for it as this is the most expensive item that we’ll be looking at here.

Pros

  • Pilot Arc - No other plasma cutter has this feature in this segment, Can cut rusty/painted metals
  • Built in compressor
  • Highest cut thickness in segment
  • Great performance - Even cuts through 3/8” at good speed
  • Lightweight (29 lbs.), PortableLong cables

Cons

  • No extra consumables

How Does a Plasma Cutter Work?​

A plasma cutter sends an electric arc through a high-speed inert gas stream (nitrogen, oxygen, compressed air, etc.) that passes through a narrow opening. During the process, the temperature of the gas is elevated to an extent that it goes into a 4th state of matter, known as “plasma”. The plasma’s hot state enables the user to cut metal. The plasma’s electrical activity makes the arc transfer the work while the metal is being cut.

The nozzle causes the gas to pass by at high speed to facilitate the cut. The gas also occupies the cutting area’s perimeter, enabling the plasma cutter to shield the cut. A pilot arc between the nozzle and the electrode is integrated in top quality plasma cutter models for gas ionization and plasma generation before the arc transfer.

Compared to saws, which tend to leave fragments and bits of metals after the cut, the ideal plasma cutter goes through the cutting process cleanly with few debris. What’s left can be removed easily. Also, plasma cutters allow for great detail because they enable users to cut through fine lines along thin metal without releasing excess heat.

What to Look for Before Going to Buy a Plasma Cutter

When choosing your plasma cutters to use at home or in shop, there are a few important things to consider that will help you choose the perfect model. The task of selecting the right plasma cutter for your needs can be bewildering, particularly for first-time buyers. 

For starters, you should narrow your search to plasma cutters with built in compressor. What this means is that the air/gas compressor will be built into the unit itself, making it a self-contained and fully functional tool rather than something that requires an additional, external gas supply. If you’re not running a manufacturing factory yourself, then this is the type of plasma cutter you should look for.

The unfamiliar device has several makers to choose from. As a result, you should approach the purchase in a logical manner. The selection of an ideal plasma cutter requires these considerations.

Input Voltage & Duty Cycle

Depending on which plasma cutter you select, the wiring needs to be configured. Most plasma cutters can be wired at 110, 120 or 220 volts. However, your garage or home might not have a 220 voltage outlet, so keep this in mind. If you have a high voltage outlet, then choose a plasma cutter that can handle high voltages.​

Most plasma cutters will offer 30 amp, 110 volts or 50 amp, 220 volts. Also, the user may have to screw the wires into the cutter’s body. For convenience, the manufacturer might screw in the machine. Some plasma cutters also have a dual meter at the front that enables users to adjust the amps depending on their needs.​

Then duty cycle is another important consideration. A plasma cutter with more amperage output will have a longer duty cycle than a plasma cutter with less amperage output. A longer duty cycle is preferred for longer shifts.

Cutting Thickness

Never neglect this aspect when you’re reading reviews of the plasma cutter. The majority of plasma cutters perform a 1” or 5/8 severance cut and a clean cut of ½”. The former requires a steady hand, along with patience. The latter can be done quickly without any issues. A good plasma cutter performs better than oxyfuel when it comes to less than 2” metal thickness. They produce faster, cleaner cuts.

The greater the thickness a plasma cutter is capable of going through, the higher will be its price. Therefore, it’s viable to know what you’ll cut before you start your plasma cutter buying hunt. In addition to its capability of going through a certain thickness, a plasma cutter may also have additional features to support the cut.

Arc & Torch

Modern plasma cutters have a pilot arc which prevents direct contact between the material that the device will cut and the torch. This prolongs the life of the nozzle. Some plasma cutting devices also come with starter sets, which allow users to position the torch and see the arc accurately.​

An ideal plasma cutter is also equipped with a new torch. The torches are customized in some branded models, and their trigger can be moved according to the user’s liking. The head of the torch may be low profile to go through tight spaces. The user can use the trigger in both finger and thumb positions in most offerings.

Portability & Cooling

Plasma cutter is used for a variety of cutting purposes and users often have to move the device around a location, from site to site or even around a plant. Acknowledging this, owning a portable brand and having additional features for transportation – such as a handle – would work in your favor. Some models also come with built-in storage for consumables and other essentials.

In addition to portability, the plasma cutter will also have some technology or feature that gives cool air flow to prevent the unit from heating up. The machine’s center is the area where heat can get trapped, so having a top-notch cooling mechanism will prolong the duty cycle of your plasma cutter. The cooling system also prevents any dust or dirt from damaging the components of the device.

Inverter

A good plasma cutter has a built-in inverter to facilitate users at remote sites, where there’s no power outlet. They rely on DC power to feed the power via a transistor-inverter of high frequency from 10 KHz to 200 KHz approximately. The inverter adds to the cost, but offers additional functionality and portability.

Digital inverter technology saves space, meaning manufacturers house modern units in compact designs with semiconductor units. Also, the inverter technology facilities high cutting frequency. In simple words, the built-in inverter enables the plasma cutter to be efficient and fast.

Price

Of course all these things also affect the price. If you have plasma cutter with built in compressor and inverter and it has an impressive duty cycle, then you can bet it will cost more than something will less impressive specs. Here you need to make the choice between a device that does only what you need it to as cheaply as possible, versus a device that will last a long time and offer the highest performance – possibly being the better investment if you do a lot of cutting.

Extras:

Remember as well to pick up some extras along with your purchase. Good accessories and supplies include:

These extras will help your device to last longer and will ensure that it doesn’t give out just when you need to use it!

  • Spare electrodes – These require occasional replacing
  • Consumables – The housing which can eventually wear out over time due to the heats being used
  • Shield cup Silicone grease
  • Air dryer/regulator – Useful for reducing slag
