Best Plasma Cutters Reviews

1. YesWelder CUT-55DS 55Amp Non-Touch Pilot Arc Plasma Cutter

image of YesWelder CUT-55DS

I love this plasma cutter and for the money, it’s absolutely the best small plasma cutter you can buy. It is relatively low-cost (it’s not the cheapest plasma cutter for sale on the market but it’s not far off) and it has a lot to like about it.

It has built-in non-touch technology that will make it so easy to cut through rough or painted surfaces without producing massive amounts of recrement. It also preserves the nozzle tip for longer, which costs you less in maintenance fees.

The dual-voltage capacity is a good function and it means you can get great cutting performance on nearly any metal and it’s even well suited for light industrial use when you switch to the 220v plasma cutter mode.

The 30-day money-back guarantee is really impressive too, give it a try and if you’re not happy with your YesWelder then send it back for a refund, they want to make sure that you’re happy.

It’s the best value plasma cutter in my tests, build in parts are durable and solid, and the customer service they back is responsive and ready to back you up.

2. Hypertherm Powermax-30 088079Plasma Cutter

1 Hypertherm plasma cutters are high quality heavy-duty machines and thus Hypertherm Powermax-30’s price reflects that. However, it has some features that cheaper models just don’t have to justify the price point which makes it one of the favorites.

This cutter has a dual input voltage as you would expect. Powermax 30XP is exceedingly lightweight and it comes with a very long torch lead of 15 feet. The power supply provides excellent cutting capacity for 1/4″ steel plate and you get very good quality cuts from it. You also get very good cutting speeds as it cuts 1/2in at 10 ipm.

If you want a handheld plasma cutter that can support delicate work and sculpture then look no further, this is the best choice in my cutter reviews in terms of quality. You get what you pay for and the plasma cutter price is fair here because the quality is outstanding.

However, it won’t gouge unlike some of the other Powermax models and some may find the fact that it’s not a 50 amp plasma cutter somewhat limiting, you can’t tackle the thickest of materials with this plasma cuter but its efficiency is still great and a top pick.

3. Hobart 500566 Airforce 40i 240 V Plasma Cutter

Hobart is one of the big players in the market of plasma cutters and the Hobart 40i Plasma Cutter’s price range reflects this. However, it cuts mild steel at 7/8″ at 50% duty cycle at a speed faster than an oxy torch! Among plasma cutters, this is a serious tool worth your consideration.

Annoyingly the Airforce 40i’s a 240V cutter rather than a 110v 220v dual voltage plasma cutter and that means you’re going to have to get a special input voltage source installed which is expensive. The ground cable on the power cord works in the same way though.

The Hobart Airforce 40i is one of the best plasma cutters that I’ve tested and I really like the fact that the airflow is designed to conserve air as much as possible, this aspect allows for a lot more flexibility than most air plasma cutter tools allow for. The duty cycle is decent too.

You almost certainly don’t need this cutter for home use but if you need to slice through the hot metal piece in the way that a knife slices through butter and you need to do it a lot in your workspace – this is the area where it excells.

Hobart 500566 Airforce 40i Plasma Cutter 240V
  • Maximum cutting of mild steel is 7/8 in at 50% duty cycle. Cuts faster than oxy fuel
  • Auto-Refire Technology - Allows operator to cut expanded/perforated metals, as well as painted or coated surfaces.
  • Operates off 240 V input power. Fan-On-Demand: The fan only runs when needed, reducing the dust and debris that is pulled into your machine.

4. Miller Electric, 907579, Plasma Cutter, Spectrum 625, 90 PSI, 12ft.

You will need to bring your own air compressor which might surprise you when you check out what price range this plasma cutter is in. However, it is a superb machine and the Miller Spectrum 625 might just be the best cutting machine of them all.

The quality is outstanding on the Miller Spectrum. The output range is among the highest of any plasma cutters I’ve tested. If you’re involved in metal fabrication on an industrial scale, you’re going to love the Miller Spectrum 625. It has an excellent duty cycle.

The Miller Spectrum’s air hose is a 12-foot lead which is enough torch line to reach cutting surfaces anywhere in a workshop. The cutting ability of this plasma cutter is second to none and without error and if you’re used to working with a grinder, you’re going to love how much easier this is to work with.

The Miller Spectrum 625 is the best value machine in my plasma cutter reviews but only if you’re going to be working with one all the time, it’s not for home use and thats the difference.

5. Forney Easy Weld 251 20 P Plasma Cutter

The Forney Plasma Cutter is a step above the entry-level. It will cut mild steel to about 1/4″ and this 120v plasma cutter is reasonably portable too (though not so light that you want to be moving it around all the time, mind you).

It has special technology for drag cutting which makes feature cutting super easy. Thanks to this reason you’ll spend less on torch expendable materials in the long run and that’s always great news.

There’s a solid warranty on this and when I spoke to their servicing department I was impressed to be dealing with real professionals, it’s clear that the customer experience matters here. Replacement parts when you need them are very easy to get access to.

The only thing missing for this mid-range machine is dual voltage capability which would be nice to have. This is the best machine at this lvl. I could find.

  • CUTS- Mild steel, aluminum and stainless steel from thin material to 1/4"* (6.35 millimeters) with ease! *(Mild Steel)
  • EASY TO USE- All you need is 120 volt power source and 1.5 CFM of compressed air. Built in regulator and air dryer make operation a breeze

  • Short power cord

6. Hypertherm Powermax 45 XP Hand System w/c CPC – 20′ Leads Plasma Cutter

This is a super portable and lightweight professional cutting machine and the Powermax 45 has a price tag to prove it. The drag cutting design is an absolute joy to use and it slices through metal so easily that even a complete beginner should get the hang of it in minutes. Just don’t forget to attach the work clamp ground clamp whatever you want to call it.

Metal fabricators, on the other side, will love the air pressure “smart sense” unit which means they never have to watch the air pressure gauge. This is a recommendation for them.

You can reach gouging amps very easily and that’s not something you can do on cheaper machines. It also has a great duty sycle.

One thing I noticed is you never get fatigue using this machine despite the super clean cuts. The Powermax 45 is excellent and for the value it brings, it’s also reasonably priced. Easily the best plasma cutter when it comes to quality.

Hypertherm Powermax45 XP Hand System w/o CPC - 20' Leads
  • Small size and light weight provide exceptional portability for a 16 mm (5/8") rated cutting system
  • Patented drag-cutting technology makes the Powermax45 XP easy to use even for first-time operators

Cons:

  • Price
  • No 120v support

7. Hobart 500564 Airforce 12ci Plasma Cutter With Built-In Air Compressor 120 V

If you want a machine with a built-in Air Filter and air compressor then the Hobart 12ci is worth paying attention to. There’s no need to mess around with pressure settings on this machine, it does it all for you.

You get a very precise cut and though the Input Voltage is a little lower than we’d like, the power output is respectable and you get a very thin kerf with little slag that needs attending to. The ground clamp is easy to attach too.

The downsides are that this is a touch model and it can be hard to get used to working with. It’s also not going to handle very thick metal task – it wasn’t designed like that. The duty cycle is fine, though.

However, the Hobart 12ci certainly represents the brand in a useful fashion though you might want to consider spending just a little bit more to get more from this plasma c. with built-in Air Filter and And Regulator

Hobart 500564 Airforce 12ci Plasma Cutter with Built-In Air Compressor 120V

8. SUPER DEAL Inverter Plasma Cutter Welding Machine 110v 220v

Need a 110 volt plasma machine that can also deliver 220 volt support? Want it at a super price? Then this 110v 220v Super Deal Direct Current machine may be exactly what you are looking for. One thing I should note that is this not a machine for welders & plasma cutters as the name suggests, in fact, it only supports metal cutting. Though a welder can use it to cut, I suppose.

For this price, I wasn’t expecting very much but I was pleasantly surprised. The build is not bad and it’s much better than most budget models of kit that I’ve tested in the past. The duty cycle is acceptable for a model this cheap too, plasma cutting doesn’t have to be expensive.

The documentation could use more thinking through thought and much of it came in Chinese figures rather than imperial measurements but really, that’s a minor complaint.

If you want a machine for occasional use that provides a decent cut as maximum duty cycle with dual voltage support at next to no money? This is my top pick. I wouldn’t choose it for heavy work but otherwise, it’s excellent.

9. PRIMEWELD Premium & Rugged 50A Air Inverter Plasma Cutter 110v 220v

Whether you need a 110v plasma cutter or a 220v model, this has got you covered. If you are a buyer that wants to get working with a plasma torch without breaking the bank then the PRIMEWELD Cut50 is a solid choice as a decision.

You can choose from a range of duty cycles which is great and it will cut cleanly through up to 1/2 inch sizes without any problem. However, it does seem to eat up consumables at a much faster rate than the other machines in my tests so their life span is not great which you should take into account.

The PRIMEWELD Cut50 customer support is excellent too if you find yourself struggling with the training guides in the box (though they’re very well put together too).

However, the cord is a bit short of this plasma machine and you’re going to want to replace it to ensure you get your amps safely. The portability of this equipment isn’t great either but given that it’s aimed at the diyers, hobbyist market, that’s probably not a big deal for this too. The cost makes it a very attractive option for buyers without a doubt.

10. Ramsond CUT 50DX 50 Amp Digital Inverter Portable Air Plasma Cutter Dual Voltage

The Ramsond Cut 50 plasma cutter is a cutter best suited to medium levels of use though it’s also pitched at the fully professional market, I felt that the “touch and cut” philosophy underpinning the design is not going to win over those owners with the most demanding household applications for a machine like this.

The build-quality is OK but I do have to note that some users report serious problems straight out of the box with this model and I would strongly advise buying it through Amazon to ensure that you get some support in the aftermath (though it’s worth noting that Ramsond’s customer service is highly praised).

It does run with compressed air which keeps the overall cost of ownership down. I also found that it delivers a nice neat cut too when it comes to the metal cutting results. Keep in mind that this plasma cutter can’t do stick welding or any other welding process it is soly for cutting metal.

Best Plasma Cutter – Buying Guide

These machines are evolving constantly. The manufacturers are working to improve and develop the functionality and user experience of plasma cutters all the time.

That means you have plenty of options to choose from but, at the same time, you may be trapped with the paradox of choice – you can’t work out exactly what differences set them apart and why some cutters are so much more expensive than others.

So, this buyer’s guide is designed to separate out the most important factors to help you find the machine that meets your needs.

Learn how hot is plasma cutter here.

Power Source

You need two power sources to run a plasma cutter. A pneumatic power source to provide air pressure(1) and an electrical one to supply current. There are some plasma cutters that use a range of gases but the most common ones are pneumatic.(2)

Pneumatic

If you want to create a plasma, you need a source of gas, for most plasma cutters that role plays the gas which is air (compressed air) and the pneumatic power source is there to create enough pressure to get that air flowing to form a viable plasma for metal cutting.

If you have a separate air compressor, then you can save a fair amount of $$ on buying a machine as those with integrated air compressors are more expensive but also save on storgage space.

Electrical

You also need to pay some attention to the form of electrical input that your plasma cutter will need. The top of the line, heavy-duty machine models sometimes use three-phase 240-volt supplies but the most affordable plasma cutters and most suitable for most purposes will use 110/120-volt, 220/240-volt, or a dual supply which allows both types of input.

The only place you’re likely to find a three-phase machine is in an industrial setting. In most instances, it’s more useful to have a dual supply of 110/120 volt and 220/240 volt.

110/120 Volts

This is the standard supply that most people have at home or in a garage. Thus, if you can use your plasma cutter at 110-120 Volt, you can use it at home. Unfortunately, this isn’t a high enough voltage to allow the machine to operate at maximum power and temperature and chances are that you may struggle to cut metal thicker than 1/4″ which means that you may need more power.

220/240 Volts

If you need this voltage, you’re going to have to install a power-point designed for this type of supply. That means spending more, if you want to cut through thicker materials though, you’re going to have to invest in this supply. You will of course also find that you cut faster and of a much higher quality with your plasma torch than on 110/120 Volt.

Plate Gauge To Cut

You will find that most plasma cutters can cut through almost any kind of metal surfaces. However, it’s the thickness of the plate that they can cut that should determine the plasma cutter that you buy.

The rule is simple: the thicker the plate you want to cut, the more amps you will need. This determines your power needs.

You can cut through different gauges of plates based on the amp and the type of metal with your plasma torch. So, let’s say your plasma cutters can only cut 3/8″ of alu plate, it will be able to cut through 1/2 inch of stainless steel and up to 5/8″ of Metal sections.

In my experience, it’s always best to factor in some room between the machine’s maximum stated cutting capability limit and the plate thickness you need to cut. In most cases, you won’t get a tidy cut if you try it at the maximum level and you won’t get the job done if you need to cut through something thicker.

Cut Finish

If you’re looking for a clean-cut then you should remember that each machine will produce a different standard of finish.

A cheap machine may be able to cut a thick plate but you’ll find a more expensive top plasma machine that will usually provide a better cut quality without failures and those are usually the best plasma cutters.

If your cuts aren’t for decorative purpose, you won’t care very much but don’t forget that a neat cut is desirable because it saves on the effort to clean things up after cutting. This is true even for fabrication job that will have the cut edges eventually welded.

You should think hard on the quality of finish you need, it’s often what helps you pinpoint how much you should spend on your plasma cutter selection.

Types of Torches To Consider:

The Lead:

The lead, that your torch is attached to the machine with, is a vital part of using a plasma cutter. You want a long lead if you have to move around a project without moving your plasma cutter around. Bear in mind that there is a variety of different torch styles that have a little bit different uses and characteristics.

If, on the other side, you expect your plasma cutter to sit on a bench in your working space for instance, and you bring the materials to be cut to the bench, you can opt for a shorter lead.

In addition, you should opt for the best quality of lead that you can buy too, low-quality leads will easily get damaged and have a short lifespan (i.e. from molten metal, sparks, etc.) and can wreck the cutting action or even render working with the torch completely unsafe.

High-Frequency Non-Touch Torch:

When you use a plasma cutter, how it works is normally to create a pilot arc which when it comes into contact with the metal forms the main arc. This can make it harder to control the cut than it needs to be.

A high-frequency non-touch torch will create the main plasma arc prior to the nozzle making contact with the project. It uses a “standoff” to keep the torch as a constant distance over the cut.

You get a very tidy cut this way and it’s a very precise way to work. If you want consistency while you cut and to keep the nozzle clean because it doesn’t touch the surface of the metal then this is the best way to go.

Drag Technology:

If, on the other side, you want to opt for a machine where the nozzle does make contact with the workpiece, you should consider drag technology. This allows the torch to cut smoothly while in contact with the work.

Without drag technology, you can end up with the nozzle adhering to the surface of the work which creates a “double arc fault”. That can bring the cut to a complete halt or worse, it creates a sort of jumping motion that distorts the cut.

In turn, it ruins the nozzle tip and leaves ugly arc markings over the work.

If you operate on artistic projects where you need to cut intricate patterns that aren’t on a straight edge – then this is the best choice for you in the long haul.

Touch Start:

A touch start model is a plasma arc cutter that only starts when the nozzle makes contact with the metal to start the cutting arc. In this regard, you have to lift it slightly above the project and, free-hand, ensure that it stays in the same position as you finish the cut.

This is an awkward process and you need super steady hands to make it work for you. No matter how good you are, you won’t get the kind of accuracy you get with a non-touch start or a drag technology electric plasma cutter.

The only exception and real advantage of this kind of plasma burner is that it’s going to be cheap. Even then, I’m not sure they’re worth it.

What Can I Do With My Plasma Cutter?

So, what is a plasma cutter for? They are super-versatile metal working tools that can tackle a huge number of tasks and ought to repay your investment, with interest, very quickly, indeed.

If you operate on build and repair projects that involve metal, you need a plasma cutter even a cheap plasma cutter will be better than nothing depending on your work environment.

Let’s overview some example projects you can work on with plasma cutters:

  • You can cut metal sections that help repair a cracked trailer frames of metal plate
  • You can cut thick metal items (just like a band saw does) to length or cut sheet metal
  • You can cut steel plate for any project you need to without suffering a hand fatigue 
  • You can dismantle a mobile car with plasma cutters
  • You can build a BBQ to order
  • You can chop metal pieces to create a welding bench
  • You can make metal fencing with plasma cutters

Frequently Asked Questions (FAQs)

How Do I Choose A Plasma Cutter?

You can determine the best plasma cutter for the money you wish to spend by taking some time to consider aspects like the power source (particularly the electrical inputs – will they be enough to support the right cutting thickness of the metal and still provide clean cuts).

As well as the finish that you need, the kind of lead you want for the torch (your projects should dictate a long or short lead), and the specific torch technology that you think will make it easiest for you to get the precise cutting that you as a metal fabricator will need on the Jobsite.

How Much Air Pressure Is Needed For A Plasma Cutter?

There is a rule of thumb that you should buy a compressor that provides around 1.5 times the (cubic feet per minute) CFM required by the plasma cutter and that this is then delivered at the PSI (pounds per square inch) required by the cutting tool.

Most plasma cutters will operate in a range of 60-120 PSI depending on the output range of the individual machine.

Why Does My Plasma Cutter Cut On An Angle?

A plasma metal cutter can end up plasma cutting at an odd angle for several reasons these can include: the torch nozzle has become worn, there is not enough power to the arc, you’re cutting too quickly for the power rating, there’s not enough gas flowing to the nozzle or you’re working at too slow a speed.

However, it’s worth noting that most plasma cutters will have a slight “bevel” (the angle to the cut) of about 1-3 degrees, this is simply due to the shape of the gas jet as it comes through the nozzle – you can reduce this but you can’t make it go away entirely.

Conclusion

For verdict, I say that my favorite plasma cutter is the YesWelder CUT-55DS. It’s a great place to get started with cutting as it is a budget plasma cutter. It’s not expensive and it packs a lot of bang for the buck into the package but it will struggle with some heavier jobs. Either way, in my opinion, it is the best plasma cutter for its price range.

The Miller Electric Spectrum 625 and the Hobart 40i are going to be the plasma cutters choices for many workshops that have a high demand for this kind of cutting, the extra cost in prices is surely going to be easy to justify.

Finally, if portability features are your top priority then the Powermax45 is a really excellent pick and among the best in the top picks above.

None of the cutters in this roundup will let you down, though, they’re all solid choices depending on your specific needs.
