9 Best Plasma Cutters of 2022

1. Hypertherm Powermax 45 – Top Pick

Click Here for Price

The Hypertherm Powermax45 is the best plasma cutter you can buy.

Hypertherm has been building high quality equipment for decades. Their reputation rests solidly on their product’s ability to do exactly what they say it will. In that regard the Hypertherm Powermax45 is an absolute beast.

This guy can make precise cuts through 1/2″ steel at 20 inches per minute all day long.

And while it carries a hefty price tag, it’s easy on consumables (186% more efficient than some models) which means it’s easier on your checkbook over the long haul.

As an added perk, Hypetherm’s plasma cutter consumables are less expensive than those of many other manufacturers. This is something that should NOT be overlooked if you’re operating a business where maintaining profit margins is important.

This type of machine was designed to be the backbone of a serious operation. It offers impressive performance, extremely high quality parts, low consumable use and is backed by Hypertherm’s incredible customer support network.

This is a machine that has 90 engineers and 15 PHD’s standing behind it. The user manuals reads like a book and offer instruction for EVERY possible situation from standard cuts to CNC control and operation.

If you have a business that requires 100% uptime this is the unit for you.

The controls on the Powermax45 are very straightforward. There’s a mode switch that toggles between three primary modes:

  • ​Continuous pilot arc – this mode allows you to easily cut perforated metal such as grating.
  • Non-continuous pilot arc – this is the standard setting used for cutting metal plate of varying thickness.
  • Gouging – for punching holes in plate metal (use specific gouging consumables for best results)

The amperage knob allows for quick adjustments to power output. This should be adjusted based on the thickness of the material you intend to cut as well as the ideal distance of the tip from the metal.

The arc-torch is comfortable to grip and easy to operate. This should not be overlooked as it makes extended cuts relatively easy on the hands.

This plasma cutter was designed from the get-go to be portable. While it is the heaviest unit in this comparison, it still only tips the scales at 37lbs. Connecting the gas and torch are quick and easy, meaning you can setup and break down in very little time.

While it’s tough to gauge reliability in a test, the Powermax series of cutters are popular with professionals for a reason. They are made with quality components and the company backs up their product with impressive customer support. This combined with the unit’s overall performance made it a lock for our #1 position.

The warranty on the Powermax 45 is a limited 3 year. The torch has a 1 year warranty.​

If you’re going to drop a couple thousand on a tool you should be able to expect a certain level of performance and reliability. The Hypertherm Powermax45 was designed from the ground up to be rock-solid.

And it says something that Miller uses some of Hypertherm’s technology and parts in their cutters.

It has ample power, operates efficiently, and offers inexpensive consumables. Cutting 1/2″ material at 20 inches per minute, it outperforms all but the higher priced Miller.

2. Miller Spectrum 625 Extreme – Best Small Plasma Cutter

Click Here for Price

Miller is another powerhouse when it comes to plasma cutting systems. Like Hypertherm they have built a reputation on solid construction, reliability, and incredible customer service. They also offer wide variety of welding equipment in addition to cutters.

The Miller Spectrum 625 X-treme is a workhorse of a plasma cutter. It’s actually rated to cut 5/8″ mild steel vs the 1/2″ max for the Hypertherm.

In terms of build construction and quality it is essentially an industrial quality tool (in fact many of it’s internal components are manufactured by Hypertherm). It even offers both 110V and 220v power so you can use it just about anywhere.

Obviously you’re limited on thickness when using with 110V.​

In performance it matches the Hypertherm Powermax45 in almost every aspect. But it tends to chew through consumables at a much faster rate. Unfortunately, the Miller plasma cutter consumables are higher priced than those for the Hypertherm unit as well.​

It offers much of the same functionality of the Powermax45 including an auto re-fire capability that allows for cutting materials like grates and other perforated metals. It also offers quick and secure attachments for the torch, gas, and power.

To be totally honest the comparison eventually came down to price. The consumables for the Miller Spectrum 625 X are slightly more expensive and the unit itself costs a bit more as well. Other than that, it would make a solid addition to any shop.

One very surprising aspect of the 625 is its’ size and weight. At only 21 pounds, it is a full 16lbs lighter than the Powermax45. This is largely due to the inverter technology utilized in the 625. If you’re looking for a unit that is extremely portable this is a huge plus.

The controls and operation of the 625 X-treme are simple and straightforward. It comes with the XT-40 handheld torch, which has been redesigned to be more efficient than previous models with consumables.

All in all this little unit packs a powerful punch.​

Miller is another company that has built their reputation on quality. The Extreme-625 is designed to be the workhorse plasma cutter in any shop or factory. They use the highest quality components and have thousands of loyal customers.

The warranty on the Miller Spectrum 625 is a limited 3 year. The torch has a 1 year warranty.​

The Miller Spectrum 625 from is a high quality plasma cutter. In terms of power, flexibility and portability this little unit holds it’s own against much bigger and heavier units. It packs a powerful punch with a consistent clean cut on 5/8″ materials. If you’re looking for a high performance machine it’s tough to beat. And if you’re looking for something lightweight, this is the best plasma cutter out there under 25lbs.

The main reason it takes second place is that they use many of Hypertherm’s internal components. If another company relies on Hypertherm’s parts, why wouldn’t you just buy the Hypertherm?


  • Impressive power for its size
  • Best cutting speed of the group
  • Half the weight of the Hypertherm

3. Hobart AirForce 40i – Best Home Plasma Cutter

Click Here for Price

Hobart has been in the business of producing quality products for nearly 100 years. Their line of plasma cutters are considered to be some of the best in the industry.

​The AirForce 40i is a highly economical and works on all conductive metals. It is based around inverter technology that is both reliable and efficient. The end result is a highly capable plasma cutting machine in a relatively portable package.

Capable of cutting up to 5/8″ steel cleanly, this bad boy can tackle just about anything you throw at it. It can even sever up to 7/8″ steel. The duty cycle while cutting 5/8″ material is 50% at 40A, 240V. So as long as you supply it with enough power, it will go all day.

Designed for heavy workloads, this is a true commercial grade cutter. The specs say it is rated to cut 7/8″ steel, but it is capable of cutting even thicker sheets if necessary. The newly designed power inverter saves space, meaning this unit is actually smaller than other units with similar capabilities.​

The Hobart 40i is simple to setup and simple to use. The unit is essentially the same as the Airforce 700i but with the improved XT40R torch. The upgraded torch is easier on consumables and has a more flexible cable. This has a dramatic impact on comfort while making longer cuts. (It’s also easier to store)

Power adjustments are quick and easy with the simple dial on the control panel. The auto-refire technology allows for easy cutting of painted or perforated materials without having to constantly manually refire the torch.​

It requires a 50A 240V outlet and 4.8 scfm @ 90 to 120 psi of compressed air. When supplied with everything it wants this guy will cut through 5/8″ all day and can even cut through 7/8″ material quickly and relatively cleanly. ​

The Hobart name is synonymous with quality. Like the Hypertherm and the Miller the 40i is designed to be the workhorse in any shop or factory. They use only the highest quality components and have thousands of loyal customers.

The warranty on the 40i is a limited 3 year. The torch has a 1 year warranty.​

With slightly less flexibility, the 40i comes in just behind the Miller. It’s slightly larger and requires 240V whereas the Miller can operate on 120V or 220V. Their duty cycles are identical, so if you don’t need that flexibility the Hobart will give you basically the same performance at a lower price range. They also utilize the same torch so consumables for both will be more expensive than the Hypertherm.


  • Hobart quality and build construction
  • Designed for commercial use and loads
  • Cleanly cuts 5/8″ and severs 7/8″
  • Impressive 50% Duty Cycle
  • Easy on consumables
  • Great for home or hobby use

4. Hypertherm Powermax 30 AIR – Best Portable Plasma Cutter

Click Here for Price

But the Powermax30 AIR from Hypertherm manages to offer both a highly portable, lightweight design, AND performance that nearly matches competitive models requiring an external air compressor.

With a max cutting thickness of 3/8″ and a duty cycle of 35% the Powermax30 AIR took the top spot in our portable plasma cutter comparison.

It’s capable of cutting a wide variety of metals including stainless steel, aluminum, mild steel, copper and their alloys. The pilot-arc ignition even allows it to cut painted materials.

It’s rated to cut 3/8″ steel at 10 inches per minute and can sever 5/8″ at 5 inches per minute. It’s inverter power supply is efficient enough to allow it to do all of this at 120V.

Hypertherm’s Auto-Voltage sensing technology allows it to operate at both 120V (20A) and 240V. And while it’s performance at 120V is impressive, it gets even better when supplied with more power.

At 240V it’s duty cycle jumps to 35% for rated cuts (as compared to 20% duty cycle at 120V). This makes the Powermax30 AIR the far and away best in terms of portability and performance.

The Powermax30 AIR uses Hypertherms IGBT inverter based power supply. It offers tons of power even with less voltage. Hypertherm actually makes parts for other manufacturers (like Miller) so you can rest assured that this product will be reliable. You can also find plenty of outlets around the US to have it serviced should the need arise.

All of the Hypertherm Powermax products have a built in filter/coalescing moisture trap/auto drain system to help extend consumable life. Hypertherm torches are also designed to be less susceptible to issues such as short consumable life and poor cut quality which is often associated with elevated moisture levels in air system of a plasma cutter. The Powermax30 AIR has a built in air compressor and a built in air “precooler” heat exchanger and moisture drain to further reduce the effects of moisture.​

If you’re looking for a highly portable plasma cutting machine you can’t beat the Powermax30 AIR from Hypertherm. It offers production grade cuts in a totable unit. It’s duty cycle (35%) is less than it’s big brother, but it will still cut cleanly through up to 3/8″ steel.


  • Impressive power AND portability
  • Comparable price range to the Powermax45
  • Auto input voltage technology allows for 110V or 220V operation
  • built-in air compressor for maximum portability
  • Pilot-arc ignition allows cutting of painted metals
  • Lower long-term costs with efficient consumable usage.


  • Not as powerful as the other plasma cutters in the top 4.
  • More portable, but less powerful


  • Duty Cycle: 35% at 50A @ 240V
  • Input Voltage: 120V – 240V
  • AC Power: Single Phase
  • Power Supply: Inverter – IGBT
  • Rated Cut: 5/16″ – 3/8″

5. PrimeWeld Cut50 Plasma Cutter – Best Plasma Cutter for Home Use

Click Here for Price

For the money, the Cut50 from PrimeWeld is the best plasma cutter under $1,000 on the market. This inverter-based model offers performance beyond even the Powermax45 and at a FRACTION of the price.

Got to be a catch right? Not really.

PrimeWeld uses the same inverter technology that ​Hypertherm first developed for their cutting systems back in the 1980s. It’s capable of consistently cutting 1/2″ stainless and 5/8″ mild steel and weighs in at only 22.5 lbs.

Given it’s price point it offers great flexibility as well. There are plenty of powerful plasma cutters out there capable of making short work of thick steel, but not all of them offer the fine level of control to work with thinner materials as well.

The PrimeWeld does both.​

This makes a great unit for the home shop, farm, or hobbiest. It offers lots of power for thicker materials and the flexibility to work accurately on thinner metals as well.

While it offers VERY impressive performance this is not the machine we recommend for someone running a business that requires high performance day-in-day-out. It doesn’t offer CNC control, or pilot-arc capability.

If pilot-arc is something you need you should check out the PrimeWeld Cut60.

​Let’s take a look at it’s capabilities.

The setup and controls of the Cut50 are pretty standard. You’ll want a reasonably good air compressor to ensure proper operation. Don’t skimp as it can impact cutting performance.

Once you’ve made all your connections set your amperage based on the material you’re going to cut and a way you go.

1/2″ mild steel was absolutely no problem for this unit. At 220V it cut through like butter. We didn’t change out the power adapter to test 110V performance, but I’d assume you would see a drop off in terms of duty-cycle and you’ll most likely need to drop your speed.

​This unit DOES NOT offer pilot-arc technology so you’ll need to make contact with the material to start and restart. If you’re planning on working with painted, rusted, or perforated metals you’ll want to consider a different model that includes pilot arc.

While it’s tough to gauge reliability in a test, PrimeWeld has a good reputation for a quality product. They offer a very reasonable return/replacement program and are generally very responsive to customer problems or inquiries.

The warranty on the Cut50 is a limited 3 year. The torch has a 1 year warranty.​

If you’re in the market for a high-performance plasma cutting system, but don’t need a commercial grade product, the Cut50 offers comparable performance to the biggest names in the industry. It’s got tons of power, works on both 220V and 110V outlets, and works well on a wide variety of materials.

It’s not engineered to the same specs as names like Hypertherm, but given it’s price point it easily takes first place in terms of value.


  • Lightweight
  • Low retail price range
  • Powerful with a solid 60% Duty Cycle
  • Consistently cuts 5/8″ mild steel
  • works well with thick and thin materials


  • Questionable long-term durability
  • Performance doesn’t match Hypertherm plasma cutters
  • Warranty & repair work requires shipping

6. Ramsond Cut 50DX Plasma Cutter

Click Here for Price

If you’re looking for a unit that offers the most bang for the least amount of cash the Ramsond Cut 50DX is the best budget plasma cutter.

We were skeptical when this model came out a few years ago as to how such an inexpensive unit would perform. On top of that there were some initial quality control issues.

This is the 4th generation of that product and many of these issues have been eliminated by upgrading the internal components.

The result is a much more solid and reliable plasma cutting system. In fact of all the inexpensive models currently on the market, the Cut 50DX is the clear winner of best cheap plasma cutter.

That’s not to say it is on par with ANY of the other units in this comparison. If you need a machine to build your business around, you’re better off forking over the extra dough for any of the three listed above. But if you just need something for odd jobs around the house or farm, it’s worth giving the Ramsond a shot.

The Cut 50DX is simple to setup and operate. The torch is not pilot arc compatible so you’ll either need to consistently maintain the appropriate distance or purchase a guide.

Cuts on materials up to 3/8″ were very clean and quick. At 1/2″ we saw noticeable degradation in the cleanliness of cuts. Anything beyond 1/2″ and you’re probably just looking at a sever cut at best.

The unit can be switched between 120V and 220V. We didn’t test 120V but would have to assume that cuts made with less power would suffer.

The unit uses digital inverter technology and as a result is very lightweight. It tips the scales at only 19lbs.

Although they use Toshiba for many of their internal parts, the unit doesn’t show any sign of being as reliable as the others in this competition. But for about a 1/3 of the price of the Miller or Hypertherm what else could you expect.

The warranty on the Cut50 DX is 1 year.

If you’re looking for a cheap plasma cutter the Cut 50DX is worth consideration. This is NOT in the same ballpark as the Hobart, Miller, or Hypertherm and should not be considered for heavy workloads. Cuts at 3/8″ and below are clean, but anything thicker and you’ll be pushing your luck.

If it’s for the home or farm this unit has a lot to offer, but for businesses that need a reliable workhorse, it’s probably best to go with one of the more robust units.


  • Great for home or farm or other occasional use (non-production)
  • Low retail price range
  • Clean cuts on up to 1/2″ mild steel
  • Simple setup and operation


  • Questionable long-term durability
  • Performance doesn’t match Hypertherm plasma cutters
  • Warranty & repair requires shipping
  • Not CNC compatible

7. Lotos CT520D Plasma Cutter

Click Here for Price

The Lotos CT520D has a lot going for it. It is a 3 in 1 unit that is capable of cutting, tig welding, and stick welding.

The unit is substantially larger than the Ramsond weighing in at almost 32 pounds. But with the extra capability this unit provides it can pretty much eliminate 2 tools from your shop.

While the maximum cut thickness of 1/2″ isn’t quite as high as that of the Ramsond, the unit is dual input voltage so it can be used with both 110v or 220v. It also incorporates the ability to perform TIG welding which makes it a powerful budget priced tool.

The CT520D does require an external air compressor. There is also an available foot petal that can be purchased separately for welding applications.

While the performance doesn’t match the Ramsond, the fact that it is such a flexible tool definitely justifies the higher price tag. When you take into consideration the fact that it eliminates the need for a tig and stick welder (if you need those) then it is VERY reasonably priced.

All of the connections on the unit are quick and straightforward. A longer ground cable would be beneficial and you may wish to consider purchasing this along with the unit. If you’re planning on using for welding you’ll most likely want to purchase a foot pedal as well.

This inverter plasma cutter is dual input voltage but you have to change the plug to change the voltage. The unit ships with a 220V adapter but you’ll need to purchase the 120V should you need it.

The cutting performance of this unit is impressive for it’s price. We were able to get very clean 1/2″ cuts with no difficulty at all. Pilot arc would be a nice feature, but would most likely bump up the price of the unit.

TIG welding performance was surprisingly good. The high frequency start works extremely well and the arc is extremely stable. The torch could be a bit better in terms of flexibility, but this is a budget unit after all. If you’re going to do DC only welding, this is a great unit.

For aluminum you’ll need AC and a unit like the AHP will offer more functionality. Lotos makes several different models of plasma cutter. Another popular model is the Lotos ltp5000d plasma cutter. You can read our Lotos LTP5000D plasma cutter review here.

As with many of the other products in the budget category you tend to get what you pay for. The CT520D is reliable, but the internal components aren’t as well made as those from Miller, Hobart or Hypertherm. This translates to some variance in performance, product life and consumable use.

Here is the user manual.

If you’re in the market for an inexpensive plasma cutting tool the CT520 offers great flexibility.. As with the Ramsond, it’s not in the same league as the Millers and Hobarts. But cuts at 1/2″ and below are clean and quick. In this regard it falls a bit behind the Ramsond. On the flip side this unit also offers DC only TIG welding capability. For the price range, that combination offers great value.


  • TIG Weld Capable
  • Cut up to 1/2″ mild steel
  • 110V or 220V operation
  • A solid home or non-production plasma cutter
  • Great budget plasma cutting system

8. Amico Cut-50 50-Amp Professional Plasma Cutter

Click Here for Price

The Amico CUT-50 is another solid inverter plasma cutter that offers quite a bit of power and a REALLY low retail price. a lot going for it.

The maximum cut thickness of 1/2″ at 12.5 inches per minute is pretty impressive for a machine that typically retails for less that $500.  It can also handle sever cuts up to 1″.  Again, pretty impressive for the price point.

It offers a high-frequency start, can cut aluminum, steel, mild steel, stainless steel, and just about any other material that conducts. It even performs well on rusty or perforated materials.

All of the connections on the unit are self explanatory. The AG 60 plasma torch is comfortable and consumables are relatively inexpensive. The torch lead is plenty long.

The unit is dual input voltage and does NOT require that you change the plug to change the voltage.

The metal cutting performance of this inverter plasma cutter is impressive for it’s price. We were able to get very clean 1/2″ cuts with no difficulty at all. Pilot arc would be a nice feature, but would most likely bump up the price of the unit.

Amico isn’t exactly a household name. They manufacture quite a few different electrical components and plasma cutters are only a small part of their operation. But the CUT-50 is a solid plasma cutting system. We wouldn’t recommend it for the backbone of an operation, but for work around the house or farm it’s certainly capable of getting the job done.

Here is the manufacturer website.

9. Hobart 12ci Plasma Cutter

Click Here for Price

While the cutters listed above are great additions to any shop, sometimes you want something that is more portable.

And while all of the models listed above are relatively lightweight and easy to carry around, the Hobart 12ci is the perfect unit when you need something that is both lightweight, compact, and portable.

One of the best features of this small plasma cutter is that it does NOT require an air compressor.

It only operates on 110V so don’t expect it to cut through anything thicker that 1/4″ (and even that will be slower than the models listed above) but it’s a great unit to have if you need something portable.​

The 12ci plasma cutter utilizes inverter technology to get the maximum amount of power from it’s small footprint. Although it is heavier than the Extreme-625 the built-in air compressor means there is one less piece of equipment you’ll be forced to carry around for smaller jobs.

It operates on 120V 20A so it will work on any outlet in your home or shop that can supply 20A. The duty cycle is 35% @ 12A and 110 VDC.

Here’s a quick look at what the Hobart 12ci is capable of cutting.

While the XT12R torch isn’t as nice as the XT40R that comes with the big Hobart it is comfortable and more than up to the capabilities of this unit. You can find the torch for sale online if you’re looking to upgrade.

Choosing the Right Plasma Cutter: Performance vs Price

There’s no sugar-coating that a plasma cutter is an expensive tool, but a higher up-front cost will often translate into better performance and lower cost of operation over the long haul.

This is especially important if you rely on your plasma cutter as an asset for your business. Here’s a quick look at the models we’ll be comparing.

When investing this amount of money in a tool it’s important to know that it can perform what you’ll be asking of it. There are literally dozens of manufacturers and the features and quality of their products vary significantly. Here are a few of the most important features you should consider. Let’s run through them in order of importance.

We understand that not everyone is looking for a production grade unit. If you’re looking for more budget friendly models, check out our inexpensive plasma cutter reviews. Here you’ll find products like the Forney plasma cutter.

These metal cutting systems give you the flexibility to work in any capacity from industrial use to an in-home shop or on the farm. They offer features such as continuous pilot arc, high duty cycles, chew up less consumables, and are more durable than more inexpensive brands.

​Each of the models that made our top 3 can handle a heavy workload, cut cleanly through at least 1/2″ of steel, and offer reliable performance day in and day out.

How Much Power Do You Need?

The easiest way to answer this is to ask yourself what type of metal you’ll be cutting and how thick it will be. One of the most important considerations when purchasing a plasma cutter is it’s power output. This will ultimately determine how thick of a cut it can make, how long it’s duty cycle is, and how quick and clean the cuts will be.

Power output is directly proportional to input voltage.

Some plasma cutters will work on standard 120V 15Amp outlets (standard in most homes).

Others plasma cutters require at least 20Amps. And the really powerful units will require 220V and upwards of 50Amps.

Before making your selection it’s important to know what type of power you currently have in your home or shop. ​ You may need to budget for hiring an electrician to get you the necessary power and outlets.

Here are some basic guidelines for choosing how powerful your plasma cutter should be. If you’re regularly working with materials that are 1/4″ thick or less then input voltage of 120v and 25 amp unit should suffice.

If you need to cut metals up to 1/2″ thick then you’re going to want a plasma cutter with at least 40 amps and an input voltage of 220V. And if you regularly work with materials that are up to 1″ thick you’ll want a unit with at least 80 Amps.

What is Duty Cycle?​

The duty cycle of a particular plasma cutter is the amount of time in an hour the cutter can safely operate. This is generally expressed as a percentage and is determined by how much amperage the unit draws. Let’s look a the Hypertherm Powermax45 as an example:

Duty CycleLoad
50%45 A, 200 – 240 V
60%41 A, 200 – 240 V
100%32 A, 200 – 240 V

So when making a 1/2″ cut that requires 45 amps of power the Hypertherm Powermax45 can run for 30 minutes every hour without overheating. Similarly it can make cuts requiring 41 amps for 36 minutes out of every hour. Cuts requiring 32 amps or less require no cooling time.

Duty cycle is less important if you’re using your plasma cutter for shorter periods of time. While a shop might require a plasma cutter with a duty cycle of 50% or higher for production purposes, a home user might easily get by with a model that has a 35% duty cycle at the same rated output.
Typically a higher duty cycle comes with larger the power requirements and a larger the price.​

What Are Consumables?

Consumables are the part of a plasma cutting system that will wear out due to use. The two that wear the most quickly are the electrode and the nozzle.

The temperature of the plasma arc in the torch is roughly 25,000 degrees Fahrenheit. The nozzle is made of copper due to it’s superior properties of heat transfer. However, copper melts at 1,100 degrees Fahrenheit.

So compressed air is circulated within the nozzle in a way that creates a barrier between the heat of the plasma and the copper, keeping it from melting.

The electrode contains hafnium which is extremely efficient at emitting electrons. The high temperatures within the torch eventually cause the hafnium to evaporate. As this happens the torch begins to misfire and the cuts will become less accurate. Handheld torches can be adjusted by the user to make up for this to a certain degree, but CNC consumables must be replaced more quickly to ensure continued accuracy.

Here’s a great article detailing all of the necessary consumables in a plasma cutter torch and the role each plays.

It’s important to consider consumables in your buying decision as they wear out regularly. If one plasma cutter is cheaper than another, but requires more regular consumable replacement (or higher priced consumables), you’ll end up spending more over the long run. As with the cutting systems themselves, you’ll find consumables for sale on Amazon.

A great comparison would be the Hypertherm Powermax45 vs the budget-priced Ramsond Cut 50DX. While the retail price of the Powermax is more than twice that of the Ramsond, it’s efficient use of consumables over the life of using the unit will most likely even out the cost.

What Other Equipment Will You Need?

Most plasma cutting systems come with everything you need minus one component. Pressurized air.

With the exception of the models that include their own air compressor, most plasma cutters rely on shop air. The amount of air pressure needed varies based on the manufacturer and model.

It’s important to understand that air flow is a crucial part of how a plasma cutter works. Clean, high pressure air moving through the nozzle of the torch helps improve the accuracy of the cut and extends the life of the consumables. This Dewalt is a great model as it is 2 stage and can provide 175PSI.

Oil, moisture and dust are the enemies in a compressed air system, and this is no different with plasma cutters. Filtration systems are typically built into the cutter, but the quality of your air compressor still plays an important role. Humidity in the air is another issue since this condenses into moisture when pressurized. It then further condenses as it is released from the compressor.

Without getting too technical, just make sure your air compressor meets or exceeds the recommendation of the manufacturer. Otherwise your cuts won’t be as clean AND you’ll be burning through consumables more quickly.

Desiccant Air Dryer & Filtration Systems

One sure fire way of making sure the air that’s feeding into your plasma cutter torch is clean and dry is to use a desiccant filter system. These remove moisture and any particulate from the air BEFORE it makes it’s way into the torch lead.

These systems are not inexpensive but can pay for themselves relatively quickly because of the money you’ll save on consumables. They can also improve the overall accuracy of the cuts. This is crucial in many CNC applications, but obviously makes sense for any type of application where clean and accurate cuts are required.

Here is the system we recommend based on our testing. It’s a great value for the money.

Where to Buy?

You can find plasma cutters and other welding equipment for sale at local welding shops, but one of the best places to look is on Amazon. They have a huge variety of products and you can read reviews that will go into great detail about the capabilities of each unit.

Budget Priced Options

While the quality of the Miller, Hypertherm and Hobart are tough to beat, sometimes you just don’t need a tool that expensive. In the past few years several lower priced competitors have entered the market. They offer impressive performance and require a SIGNIFICANTLY smaller upfront investment.

It’s important to understand that these units are not going to offer the same day-in day-out reliability and performance of the higher grade products above, but for smaller jobs and less frequent use they can be an exceptional value.

Here are a couple things you should be aware of before purchasing one of these budget models.

  • Service & Support – many of these models are made overseas and will offer little in the way of support. Many WILL replace parts or the entire unit, but they won’t offer much help with questions about issues that come up.
  • Lower Quality Components – while many of these units offer similar performance specs as the more expensive models they often include cheaper power supplies, torches, grounding wires, and fan systems. This can lead to performance issues and a shorter overall life.
  • Higher Consumable Use – All plasma cutters chew up consumables, but the less expensive models tend to use them faster. Over several years of heavy use this can even offset the initial savings of buying a cheaper model. If you’re using it infrequently this should never be an issue.
  • Businesses Come and Go – Some of the companies making these units haven’t been around that long. It’s possible they could disappear and you’re left with a product that no one will support. This is much more unlikely with Miller, Hypertherm, or Hobart as they have been around for decades.
