Buyer's Guide

We hope that our comprehensive review of the top four plasma cutters and the best flux core welder on the market helped you in making your decision. However, we firmly believe that a decision should be based on more than just a review, even if the review comes from a reliable source.

The importance of choosing carefully

Your future plasma cutter or flux core welder is going to serve you for years. We can advise you on the best products on the market, but we can't know what you are specifically interested in. That's why, in order to pick the best of the best for you, you will have to ask yourself a few questions.

What do I need my new machine to do? How powerful does it need to be? Am I going to use it at work or at home? Do I need it to be very light and portable, or will I mostly keep it in one place?

These are just some of the questions you should consider prior to making your purchase. However, even knowing exactly what you need may not suffice - this is where we come in.

When choosing your new machine, be it a plasma cutter or a welder, you will need to consider a whole array of factors. It's important not to rush this process, to carefully review all the products you're interested in, and make an informed decision.

We want you to make a decision that you will be happy with for years. For this reason, we ask that you consult our comprehensive buyer's guide.

What to pay attention to when choosing your new plasma cutter?

As said above, a plasma cutter is a purchase that is made once and held on to for many years. Many factors come into play when you choose the best plasma cutter. Here are the most important ones.

Cutting speed

Cutting speed


This is an obvious one. Different projects require different speeds, so first, ask yourself what kind of things you will be making. Your goal is to get the machine that is most tailored to your needs.

Before making your purchase, you will need to determine the thickness of the metal, as well as how fast you want to cut it. Some plasma cutters provide cutting qualities such as a quality cut, rated cut, and severe cut. But what do those mean?

Quality cut gives excellent quality cutting of thick materials. However, it also takes up a little more time.

Rated cut is the best of all three - it is known to provide the best and highest quality cut. In this situation, the plasma cutter will be used for cutting through mild and less thick steel. This will be done at the maximum cutting speed. Due to the relatively light metal, the cut will come out smooth and clean.

Severe cut is the slowest of all three, but it is capable of cutting through the thickest of materials. This is a heavy-duty type of cut that will withstand almost anything. The speed, slow at first, increases as your machine cuts through the metal. It's worth noting that this cut requires the most clean-up of the three.

While most plasma cutters can handle all of the above, some are better suited for a specific type of metal. This is why, before you make your choice, try to decide on which metals you will be using the most of all.

Duty cycle

This is yet another crucial feature that you must consider before making your decision. Some may even call it the most important of all. What exactly do you need to consider?

This all depends on how often you will be using your new plasma cutter. If you are a hobbyist, it's likely that you won't use it as much as a person working in an industrial setting would. This means less general wear-and-tear, but it also affects the duty cycle.

The plasma cutter that has a higher maximum amperage output will generally have a longer duty cycle. Those with lower amperage, on the other hand, will have a smaller duty cycle. If you plan on using your plasma cutter consistently during long shifts at work, you definitely need a one with a high maximum amperage rating.

Input power

This is a factor that is often overlooked when purchasing a new plasma cutter, but it definitely shouldn't be. That's why it's quite high up on our list.

Almost every plasma cutter requires high amounts of electricity to be used. That's just how it is - they are powerful, industrial machines that will rack up a bit of a power bill. Fortunately, in a home setting, you won't notice it as badly due to the lower use. In an industrial setting, the power bills are equivalent to the amount of work being done and aren't a major issue.

plasma cutter requires high amounts of electricity


Plasma cutters are generally designed to operate at 110 volts or 220 volts. As said above, they all have amperage ratings. You have to make your decision based on the minimum amperage requirement of the plasma cutter. It has to match the electrical outlet that you will be using - the outlet has to be able to handle the plasma cutter.

A handy tip is to dedicate an entire separate outlet for the plasma cutter. Why? Because if you also plug in other appliances, they will be taking power away directly from the plasma cutter. This can be problematic, so ideally, you will want to have a dedicated outlet.

Air supply

The vast majority of handheld plasma cutters use normal air for the cutting process. Some users, especially in industrial settings, may opt for using bottled nitrogen as opposed to bottled air. The reason for that is bottled nitrogen is less expensive, but that's not all. Nitrogen is believed to be drier than compressed air, which makes it suited for stainless steel cutting projects. It's also assumed to produce less oxidation.

If you intend for your plasma cutter to be portable, it might be troublesome to have to also carry a bottle of gas along with the machine. In those situations, if you're cutting thinner materials, you may consider getting a plasma cutter that comes with a built-in air compressor. This feature makes the plasma cutter light and portable, and also saves some money.


Plasma cutters usually have two kinds of start-ups: contact start and high-frequency start which initiates the pilot arc. Why is this important? Because if you are planning on using the plasma cutter near any electronic devices (such as a telephone, computer, television), a high-frequency machine may cause several disruptions and interferences on those appliances.

A plasma cutter with contact start technology does not cause any interferences. It also grants you a visible pilot arc, which helps you position the torch.

If you don't plan to use your plasma cutter around any type of electronic devices, you can freely pick a high-frequency cutter. Otherwise, consider one that uses the contact start technology.


The environment and the surroundings are two key factors in choosing the right plasma cutter for you or your business. A dirty environment will provide dirty air supply to the plasma cutter, which affects a plethora of factors.

As an example, a lot of dust and dirt will affect both the cutting accuracy and how clean the cut is, but also the durability of your device. How to prevent that?

There are specialty plasma cutters on the market, built for environments with heavy dust and metal shavings. They come with a built-in fan or wind tunnel technology which works to prevent issues and increase accuracy even in dire circumstances.

When it comes to the wind tunnel design, the cooling air is flown through the device without blowing over any electrical components. It blocks the dust and dirt from settling on the PC board of your plasma cutter.

With the fan-on-demand design, the cooling fan only runs when necessary, once again preventing dirt from entering your machine. If you work in a dirty environment, such as a workshop full of heavy metal shavings, consider purchasing a plasma cutter that uses these technologies.


Although portability may not be the most important factor, it is still something to consider. How often you may need to move around with your machine will affect the type of plasma cutter you might want to purchase. Some plasma cutters can weigh a lot more than others. The lightest cutter on our list weighs a mere 16 lbs, making it suited for those that are often on the move.

Whether you move around a lot largely depends on not just the setting that you work in, but also the type of material you will be dealing with. If you can see yourself often needing to walk from one job to another, consider buying a plasma cutter that is on the lighter side.


This is a quick one, but definitely worth considering. Your plasma cutter will come with a few consumables already included, but there will come a time when you need to restock. Before you order your new machine, make sure that the consumables are readily available too.

What to consider when buying a flux core welder?

What to consider when buying a flux core welder


While we have one flux core welder on our list, we still want to make sure that you are familiar with the things you should consider prior to making your purchase. Much like a plasma cutter, the welder is a machine that you will not be buying again for many years. This is why it's so important to pick one that you will be happy with.

Below you will find a quick list of things to consider when picking up your new flux core welder.

Input power

A typical welding machine can run on 110V or 220V circuits. A lot of welders - including the one you found on our list - offer a dual voltage capability, which greatly increases welding flexibility. This is definitely something you will want in a new welder.

Material type

If you are going to be welding thicker material, input power once again plays a key role here. For thicker material, we recommend picking a 220V capable machine with a high maximum amp rating. Keep in mind that higher voltage doesn't necessarily mean more power.

Amp rating

When it comes to welding machines, the amp rating will give you a good idea about the potential of the welder. It shows how thick or thin the material has to be. If you know you will be working with thick materials, consider a machine with high maximum amp rating.

Duty cycle

Just like with plasma cutters, the duty cycle for flux core welders measures how long within a 10 minute period the welder can produce a welder current. If you need a machine that can continuously operate for longer periods of time, you should take a good look at the duty cycle.

Heat protection

This is a fantastic feature that is definitely worth keeping in mind. Welding machines operate under extreme conditions sometimes, and heat overload is not that rare. A machine with a built-in heat overload protection system will make sure that the MIG machine is shut off if it overheats.

Heat protection systems defend both the machine and your workplace. If possible, especially for the welders that are going to be used frequently, consider this feature.

Other factors

Other minor factors that we highly recommend you consider are:

Wire size & type



Whether it's a plasma cutter that you need or a flux core welder, our aim with this article was to properly acquaint you with both of those machines. We know that workshop environments aren't easy - whether you cut or weld for a living or as a hobby. Choosing the right machine is more crucial than ever in such places.
