Looking for a cutting machine loaded with power and precision? Maybe you need a plasma cutting machine for repair work, or are looking for a cutter that can cut intricate designs in high quantity? Whatever your need, there is no doubt that the impressive plasma cutting machine packs quite the punch. From art galleries to automotive shops, plasma cutters are skyrocketing in popularity, likely due to their outstanding features. With their ability to cut intricate designs at mass volumes and slice through steel, aluminium, brass and copper in top-notch speed, plasma cutters are no longer just a staple on job sites. More and more are purchasing them for their personal use. Efficient, fast, and capable of highly advanced craftsmanship, there is little not to recommend. That being said, it can be overwhelming trying to decide on the perfect plasma cutter designed to fit your needs. Not all plasma cutters are made equal, so before committing to purchasing one, there are some questions you will first want to address.
What Will You Be Using It For?
The first question you should ask yourself is “What will I be using this for?”. As many plasma cutters serve different purposes, it is important to recognise which one would most suit your needs. For example, some cut circular, others only linear. What type of metal you will be cutting will also dictate which machine will best serve you. Additionally, you will want to ask yourself:
- How thick is the metal I will be cutting?
- How quickly do I need to cut?
- Metal Density
It is critical that you know the overall thickness of the material you will be cutting. Contrary to welding machines, plasma cutters require high voltage and low amperage levels. However, it is important that you do not decide on which cutter to purchase simply because of the amperage rate alone. The thicker the material the higher the amperage, but the less dense the material the lower the amperage. Therefore, if you are cutting material that is half an inch thick, you want to be on the lookout for a higher amperage cutter. Although a cutter with lower amperage may be capable of cutting, the cuts itself will not be of high quality. Each plasma cutter has a range of thickness they recommend in producing the best results, so make certain that it is on par with what you will be using it for. For example, a machine that has 80 amps of outlet will be roughly at its top performance quality when cutting between ¾ – 1”, whereas a ¼ machine will require roughly 25 amps of output.
The rate at which you will be cutting is entirely up to you. If you are using it in a manufacturing capacity where producing in mass quantities is required, you will want a plasma cutter that cuts quickly. The speed will not be a vital factor to one using the cutter on a less frequent basis. When purchasing a cutter, look for the cutting speeds for the metal density measured in inches per minute, also known as IPM. For example, if you are searching for a machine to cut a metal that is ¼ inches thick, then a higher amperage will cut through much more quickly than lower one. It will be useful to remember the best choice would be to select a machine robust enough to withstand about two times your regular cutting thickness. For example, a ¼ inch piece of steel is probably best suited to the class above, the 60 amp cutter. What this will ensure is that not only will the cutter be able to withstand your desired speed, but it will also produce high-quality results.
As with most things in life, when we decide we must purchase something, we tend to search for lower costs available. Although you may not require the most state of the art plasma cutter at your disposal, you also don’t want to choose solely based on a low cost. It is also worth noting that a high-quality machine does not have to be high cost. If you are on a budget, there will be specific types much more costly. For example, a CNC plasma cutter (regardless of the brand name) will be a costly, although worthy, expenditure. Before you make a decision, it will be helpful to look more closely into some of the features of the machine itself.
There are various metals which make up the plasma cutter itself. If the plasma cutter table is made of steel, it will certainly have stability and firmness not as present in aluminium, though that does not mean aluminium is not a solid choice. Both are durable metals, and both have their advantages. Is the machine something that must be easily transportable? If so, you may be interested in steel plasma cutters as aluminium, though stronger, will be bulkier whereas steel is easier to manage.
The table itself is also incredibly important, as it dictates the quality of the work. A larger sized gantry can be a bit harder to manage due to its heaviness; therefore accuracy and efficiency may be sacrificed. A torch that is light, however, will offer more flexibility and ease, thus more exact cutting results.
Servo vs Stepper Motors
There are two types of motor options for plasma cutting machines, a servo motor and a stepper motor. Servo motors are of a higher calibre than a stepper motor. A servo motor has an outstanding range of motion and can shift into many positions. It also can inform the controller of its exact location. More restricted in its range of abilities, a stepper motor has a restricted range of motion and fewer position options. Whereas the servo responds to the commands of the controller, there is no way, in fact, to know if a stepper motor has succeeded in what the user requested. Servo motors are traditionally more expensive, and you may not require that level of advancement. The most important thing to remember, regardless of the motor, is which plasma cutting machine will be most beneficial for you and produce high-quality cuts.
It can be overwhelming trying to sift through what makes one cutter costlier than another. One thing to be aware of is that different plasma cutters have different torches. These torches may require maintenance and replacement due to constant wear. The plasma cutting torches have several parts, known as consumables which will break down over time. It is to your benefit to look into a plasma cutting machine which has the fewest number of replacement parts. Fewer consumables mean less cost put towards repairs.
Inquiring about the longevity of these replacement parts will be beneficial. Choosing a plasma cutter with long-lasting parts will be a wise investment. Although it may seem costly up front, it will be worth it financially speaking in the long run. When deciding between machines, take note that some companies will rate replacement parts by some cuts, while others use a different way of measuring.
Other things you will want to consider before purchasing:
Portability – Will this be a machine you need to take on the move? If so, keep in mind that a lightweight machine will make transportation less burdensome. Additionally, a machine with plenty of storage available for your torch and other consumables will make moving from site to site much easier.
Safety – There is truly nothing more vital than your safety, so be sure to find a machine that has an actual safety sensor, which will prevent the machine from moving an arc until the nozzle is in place. A shield cup can be useful, although not entirely reliable. There are also machines that will offer a warning before the arc begins moving. There are plasma cutting machines that provide a three second or so notice before initiating, allowing the user to cut with safety.
Warranty – Anything can happen, even with the most top of the line machines. Therefore, always make sure to check how long the warranty is, with more extended warranty obviously being the better option. Also, consider how long the warranty is. Does it include all parts and replaceable, or just a select number and type? Is there a warranty extension? How much are the parts past the warranty dates? These are all things which you may want to consider.
Whatever your need is, there is one thing that is certain- a plasma cutter is a useful and powerful machine. Keeping all these factors in mind will hopefully help you in deciding which is the best plasma cutter to suit your needs.
