Buyer’s Guide (Tips & Tricks)
The ten products above are the best plasma cutters you can buy today. You might wonder about the parameters that we used in choosing them. Well, this section discusses these parameters and their importance.
Which is more important: Performance or Price?
It can be a dilemma choosing between the cost of a plasma cutter and the price. On one hand, you want to spend the least amount of money possible; on the other hand, you want a unit that gives you the best performance.
When faced with such a problem, here is what we advise;
First, be clear about the purpose of the unit. Once you identify what you need the plasma cutter for, then look for the available models that can help you achieve the task.
After this, compare the models you have drawn up; checking for any bells and whistles that add to the price without adding any value to your work.
After doing this, you will likely choose the best product that offers a perfect balance between price and performance.
It is essential that you remember that the initial cost of buying the unit isn’t the only factor that affects the price. Consumables are also important. This leads us to our second important factor.
What are consumables? Simply put, these are the parts of the plasma cutter that wear out over time. In most units, they include: electrode, retaining cap, shield, swirl ring, and the nozzle.
As the name implies, the shield helps to protect the unit and other consumables from sparks. Nozzle and electrode are the consumables you will spend the most amount of money on because they are “consumed” quickly.
With this in mind, before choosing a plasma cutter, consider the type of consumables it uses, how quickly it ‘eats’ through them, and the cost of getting new consumables.
In simple terms, a pilot arc plasma cutter completes a circuit without touching the material you are cutting.
On the other hand, regular plasma cutters need to have contact with the metal being cut before a circuit is completed.
The advantage of a pilot arc model is that you can cut through different metal surfaces (rusted, dirty or painted) without any hassle.
Plasma cutters come with different power requirements. Some are 120V, others are 240V, while others are dual-voltage units. 120V units are great for folks just starting to learn while the 230V are more suitable for advanced welders.
In our opinion, the best options are the dual-voltage units as they can switch depending on the amount of power required.
Type of Cut
There are three main types of cutting quality that you will get from a plasma cutter. These are: rated cut, quality cut, and severe cut.
The rated cut is the fastest and is primarily for cutting relatively thin steel. It is the best cut and delivers pretty clean results.
Quality cut is good for cutting thicker metals. It is not as fast as the rated cut.
Sever cut is the slowest type of cut, although the speed picks up when you cut through thin metals. Although it can cut through thick metals, it often leaves a messy residue and poor finish.
This important factor is defined as the time you can cut your metal before it starts to overheat and needs to be cooled. The duty cycle is represented as a percentage. For instance, if your unit has a duty cycle of 40% at 40 amps that means that you can cut with 40 Amps output power for 4 minutes in a 10-minute duration.
The best options on the market often come with higher duty cycle ratings.
Maximum Clean Cut and Rough Cut
There is a maximum thickness of metal that your plasma cutter can cut through without producing slag. This is referred to as the maximum clean cut.
The rough cut is the thickest level the plasma cutter can ever cut through. At this stage, expect plenty of slag, cleanup, and ugly finished edge.
Before choosing a unit, check out the manufacturer’s thickness rating of these cuts.
When buying a plasma cutter, the type of cutter you buy will be affected by the type of work you plan to do. Plasma cutters are not like oxy-fueled cutters since they are far more versatile and can cut through different types of metals.
For welders that usually cut ¼” thick metals, it is smarter to invest in a lower amperage unit. If you cut thicker metals, then you will require a unit with a higher amperage rating.
It is important to specify the purpose because if the plasma cutter is always working at the limit of its current capacity, the chances of creating poor quality cuts is quite high. You will likely end up with shoddy cuts that will ruin the quality of your work.
From our research and testing, we observed that most ¼” plasma cutters have about 25A output, ½” units have around 60A output, while ¾” units have up to 80A output.
Speed of Cutting
The next feature you should consider when choosing a plasma cutter is the cutting speed. Since projects are different, you will require different speeds. The options we have reviewed have IPM specifications, i.e. (inches per minute). The IPM is the cutting speed of the unit. If you mostly cut ¼”, you will need a unit with high amps rating because the higher the amperage, the faster the cutting speed.
The Start Method of the Unit
It is essential to consider the starting method of your plasma cutter before you buy it. Plasma cutting usually requires ionized air to get the current flow required to form the plasma. Several of the options on the market are equipped with a pilot arc that conducts electricity via high frequency. This method of starting makes it very easy to start the unit, but it comes with a problem. The high frequency can affect other electrical equipment in the vicinity.
If you are working in such an environment, it might be better for you to find a plasma cutter that utilizes the lift arc method. The lift arc method eliminates the problem of high frequency.
Portability is quite important when choosing your unit. A lightweight, compact, and portable unit can make your work easier. Look out for units that come with carrying cases, ergonomic handles, and other features that will make it easier to move the unit around. A compact unit is also important if you are working in tight spaces.
If you are working in an environment that exposes your equipment to several dangers, then you need to get a model that comes with features that will help it last for a long time. Some units are designed with a protective cage around sensitive parts, for example, the air filter.
Ease of Use
It doesn’t make sense to buy a unit that you can barely use. That is why it is essential to look for a product that is quite easy to use. Look for options that come with a panel that is easy to read. It should be designed properly and should be usable even by folks with little experience welding.
The plasma cutter, when used wrongly, can be a dangerous machine. That is why safeguards need to be put in place to ensure safe use. Some safety features you should consider include safety sensors and pre-flow sequence.
Air Compressor and Desiccant Air Dryer
The plasma cutter requires air to create the plasma, which is why it needs the air compressor.
Furthermore, using the right air dryer will lengthen the lifespan of your consumables and help you achieve cleaner cutting results.
Some units have an in-built air compressor, while others do not. Those with an in-built compressor are more convenient to use since you don’t have to carry two different tools separately. However, they are more expensive to acquire.
From the review above, it is quite clear that there are some really good plasma cutters on the market. From the reviews, our number one choice is the Hypertherm Powermax30 XP. This excellent product balances cost, design, and features to be one of the best plasma cutters you can buy right now. It is a dual-voltage unit and is made of high-quality materials.
We hope that this post will assist you in making the right buying choice.
