Plasma Cutter Buyer’s Guide

Buying the best plasma cutter for any given situation isn’t always easy since it’s not like buying a regular saw – plasma cutters are very intricate tools that are just as dangerous as they are effective. Getting something wrong can lead to the tool not working at best, and the entire thing breaking at worst, so it’s good to know what you’re getting into.

Torch Types

Plasma cutters are tools designed to slice through things like mild steel sheet metal, using hot plasma as the blade. This is often done using air that’s been heavily compressed and electrically conductive materials to create the plasma, which comes out of the torch (the handle). The key thing to understand about plasma cutters is that they aren’t all identical in terms of results.

The torch used on your plasma cutter can make a big difference. First of all, think about the torch leads (the cables that connect them to the plasma cutters): a longer lead gives you more freedom of movement but also means that you’re stretching a cable across a workspace or an open area. A shorter lead is harder to cut accidentally, but it won’t go as far. Obviously, if you don’t need to go very far, there’s not always a reason to go for a bigger lead.

Quality matters here, too. The weaker a lead is, the more likely it’ll be to get damaged, which can stop your plasma cutters from working properly. Plasma cutting tools need to avoid damage as much as possible, especially while they’re actively being used for plasma cutting jobs. This also goes for the air they use, since damaging an air lead or air tank can lead to something going wrong during the cutting stage.

Input Voltage and Power

If your plasma cutters require a certain level of power, you need to give it to them. Too little power will stop the plasma cutters from working since the pilot arc might not work as it’s supposed to. Too much power can overload the technology on the inside of the plasma cutter, breaking it or even making it explode depending on how extreme the new amount of power is.

Not all plasma cutters are able to operate for the same amount of time as one another, either. Cutting one sheet of metal is fine, but if you need to cut 50, plasma cutter models that aren’t designed for long-term use might overheat. Having the right technology makes a significant difference.

The Pilot Arc

Not all plasma cutters use a pilot arc, but the ones that do are often able to start quickly and maintain better cutting speeds without having to “warm-up” first. This can make it far better at cutting through multiple separate surfaces on short notice, or dealing with tasks that need to be completed as fast as possible, but it can also take more maintenance. Not only that, but plasma cutters that use them require fuel for them, which can cost more in the long run.

It’s up to you whether or not you get models that have them. You can often turn them off or remove them, but this isn’t always an option, so do your research ahead of time and make sure you know exactly what you’re buying. A pilot arc may not cause any problems, but having one that you don’t need can add to the cutter’s weight and leave you stuck with more cables you don’t want.

Reviews

As strange as it might sound, visiting the right reviews makes a big difference. Some people run sites to earn advertising fees by advertising and linking to Amazon pages of certain items, usually because they’re a participant in the Amazon Services LLC associates program: an affiliate advertising program designed to provide money and other benefits to people who promote products. This can lead to bias, especially if it’s not a technology-focused site that might not have the best level of expertise on how a plasma cutter works.

If any independent reviews mention a certain plasma cutter for sale, remember that they might be getting paid for the review. This doesn’t mean that it’s not the best plasma cutter for you, but you’ll want to avoid going in blindly and buying it “just because,” especially if you’re looking for certain types of technology.

What is the Best Plasma Cutter for the Money?

The best plasma cutter for you in your price range is whichever one can do the job best. No two plasma cutter machines are identical, and it comes down to what they can offer you – if they’re only designed to sever small pieces of metal from one another, they might not work well for larger tasks. On the other hand, if they’re rated with a low cutting inches per minute, they might not be good for jobs that have to be done quickly. Always choose something that works for you, and make sure you consider whether it actually meets your needs.

What is a Good Inexpensive Plasma Cutter?

Plasma cutter price ranges matter more than you might think. Most of the time, a higher price means better technology and safety features, at least up to a certain level. Going for the cheapest possible option can actually be dangerous, and you can’t always just install a new power supply or stick to a 50% duty cycle and hope that it fixes the problem.

What is the Best Plasma Cutter under $500?

$500 isn’t a bad price range for a plasma cutter, especially a brand new one. In fact, it might be higher than many of the best models you could find – just be aware that price isn’t the most important thing: quality and suitability are. If the ideal plasma cutter you need is slightly above your budget, it’s generally worth getting it, rather than settling for one that’s inferior just to stick within the limits you’ve set for yourself.

Expert Tip

If you have to assemble your plasma torch, make sure you do it properly. Not only does it have to manage the electricity, but it’s also a place where gas and coolant can flow: do things wrong, and there’s a chance of causing a small explosion or overheating the entire unit.

Did You Know?

Some units can reach over 45,000 degrees Fahrenheit, which is almost 25,000 degrees Celsius – that’s just under 250 times the boiling point of water.
