Types of Plasma Cutters

The following are the types of plasma cutters typically available these days:

  • Manual

This type of cutter comes with smaller power supply compared to the mechanized one, and also features hand-held torch (plasma) for cutting through metal pieces. A handheld plasma cutter is usually versatile and easily maneuverable, offering you a wide range of applications in terms of metal cutting.

The amperage of a manual gas plasma cutter ranges between 30 and 100 Amperes, but can sometimes go as high as 200 Amp. Generally, manual cutters can cut through metals with a thickness ranging between 3/16 inch and 11/4 inch.

  • Mechanized

A CNC plasma cutter is essentially a mechanized cutter and is generally larger in size than a manual cutter. Mechanized cutters also come with THC or torch height control that can be used for height sensing as well as voltage control.

A mechanized plasma cutter table can be as large as 48 ft X 120 ft or as small as 4 ft X 8 ft, which affects the maneuvering of these machines during operation. However, these days you can also find mechanized portable plasma cutter in the market.

  • Multifunctional

As mentioned earlier, plasma cutter and welder combination is very popular these days and can prove to be highly cost-effective. You can look for plasma cutter 3 in 1 that comes with TIG welding, stick welding as well as metal cutting options so that you can get all three jobs done by a single unit. Some of the best multifunctional cutters have been reviewed earlier in this article.

How To Choose A Plasma Cutter – Buyer’s Guide

The top cutters available today have already been listed out for you, but how do you know which one of these you should buy?

Your plasma cutter purchase decision should be based on several important factors mentioned in the lines below:

The very first consideration that you need to make is to decide the amount of metal thickness you will need to cut most of the time. Majority of the cutters get rated on the amperage and cutting ability they possess.

This means that if you are looking for a cutter with the ability to swiftly cut through metals that have ¼ inch thickness, you need to opt for a cutter with lower amperage, and if you want to cut through thicker, you need to go for a cutter with higher amperage.

  • Conduct Proper Test

The best way to select a cutter is by testing cut ability of various machines, and by testing the speed rate of these machines when cutting through metals with the same thickness. Comparing the cuts should be based on the precision of the cut as well as an examination of the slag/dross left behind in the bottom side.

You also need to find out if the gap that is left after the cut (kerf angle) is angular or perpendicular. Opt for a cutter with focused and tight arc so that the cuts are fine and polished. Also, find out how far the cutter can be moved while maintaining the arc; if the arc is longer than the machine can easily cut through thicker metal plates.

As you may require the cutter for several different cutting applications, you will have to move around the machine as frequently as possible across long distances.

A lightweight and portable machine will ease your transportation issue. Most of the products mentioned in the review come with portable handles and ergonomic design, so selecting a cutter from the above-mentioned list should not be a problem.

  • Easy Operation

You will also need to find out how easily you can operate the machine and how comfortable you feel using the unit. Make sure that the instruction manual of the cutter you choose is user-friendly and easy-to-read.

This will help you when the machine is new, and you still need to learn how to use it. It will also help you understand better how to handle troubleshooting issues and assemblage of the machine when required for operation.

The better the ergonomics of the machine, the more comfortable you will feel when using it. So, make sure that you invest in a unit that comes with great, comfy design.

  • Safety Features Is A Must

It would be foolish of you to invest in a cutter whose safety features are vague. Make sure that the unit you buy comes with inbuilt safety features like overheat protection, which will keep you and the machine safe when operating on metals for a longer time span.

How to Use The Machine

In order to learn how to use this metal cutting machine, you need to find out how you should set up the machine properly for operation. The following lines highlight the way you need to set up the machine for use:

Voltage Setting

Due to the fact that plasma cutters are not always automatic, you need to make adjustments in the output setting of these machines. It will do you good to keep the voltage at the highest setting initially to cut through metals swiftly and precisely.

The products reviewed earlier in this article mostly come with dual voltage option, which means that you can either provide a power supply of 110V or 220V for using these machines. This is an added advantage for you as you have the freedom of using these cutters wherever you get a power supply so that you can continue your metal cutting work no matter where you are.

Accessories For The Machine

Another factor that you need to consider while using the plasma cutter is how to accessorize this machine. Today’s cutters come with accessories that can be easily assembled and used for better results. Using a drag cup can help you when trying to cut a flat large metal piece like floor pans and quarter panels.

Also, it is a good idea to invest in extra consumables as there are times when you will need them while operating the machine.

Parts Check

Don’t forget to check the electrode and tip as regularly as possible, as worn out parts can affect the end result dramatically. Similarly, conduct a thorough check of the air compressor and other essential parts before you start using the unit, as improper air pressure or contamination in the cutter can cost you heavily as soon as you turn on the machine.

Cutter Parts

Generally, a plasma cutter comes with the following parts:

ASC or Arc Starting Console – This part is required for producing spark within the cutter for creating the arc that will cut the metal piece. The voltage requirement of the ASC is generally 5000V with 2 MHz frequency (AC).

The Cutter – The cutter works to align the different consumable parts of the unit and to cool them accordingly. The plasma cutter tip, electrode and swirl ring are usually required for generating the arc and are aligned with the cutter. The retaining caps (outer and inner) of the cutter act as shields and hold the parts together in place.

Materials You Can Work With

The materials that can be cut using a plasma cutter generally include stainless steel, carbon steel mild steel, alloy steel and other varieties of steel.

These days, however, plasma cutter for aluminum, copper, cobalt, magnesium and other metals are also easily available, some of which have been mentioned in the above review. While plasma cutter for glass is rare, you can conduct some research to find a good one online or offline.

Plasma Cutter Accessories

Accessories like the plasma cutter drag shield and protective cage are also available in some of the best models in today’s market.

The drag cap works to keep the nozzle safe while in use, while the protective cage ensures the safety of the sensitive inner parts during operation.

You may also require protective gear while using this metal cutting machine, which is why investing in plasma cutter glasses can prove to be a good idea.

Power Supply

The power supply of a cutter generally comes at 40 amp, 80 amp or 100 amp, but there are ones with higher or lower amperage requirement.

Depending on how heavy your usage is going to be, and on the kind of metals you will need to cut, you should choose a cutter with the right amperage. If you will need the cutter for light work, then opt for low amperage, but if you have to cut through thick metals, it is best to opt for a cutter with higher amperage.

Voltage Required

Generally, the voltage requirement for a plasma cutter is either 110v or 220V. There are some machines that come with 120v power supply. The need for proper voltage supply for a cutter has been clearly described below.

However, these days units with dual voltage option are easily available, which enables you to use such machines whether the voltage supply is 110v or 220V. Your choice of cutter should be based on the amount of voltage supply you get in your workplace.

Advantages Of Using A Plasma Cutter

The reason why plasma cutters are so popular is that of the several benefits associated with using these machines. Here are some major advantages of using this metal cutting tool:

Cuts All Metal Types

The traditional metal cutters cannot cut through all metal types, but the plasma cutter can easily cut through various metals including stainless steel, titanium, carbon steel, nickel alloys, copper, cobalt, magnesium, cast iron and aluminum. If a plasma cutter can conduct a metal, it can cut the metal easily, making it convenient for you to cut different kinds of metals with this machine.

Portability

In general, the majority of metal cutting machines are pretty heavy so carrying them around can be quite tough, especially at the workplace. These machines come with high power and need to be stabilized at a specific permanent position before you start using them. But that is not the case with the newer versions of the plasma cutter.

Today’s models feature portable as well as lightweight size, and their design includes handle for carrying these machines around during work. With the decrease in weight and increase in efficiency, opting for the latest models including the ones listed above can prove profitable to any professional or hobbyist.

Depth Or Speed

The cutters available today come loaded with technology that enhances their performance in comparison to other metal cutting machines. The high amount of heat generated from an ionized gas stream, forming an arc, improve the metal cutting ability of the machines. This way the speed of the machines also increases, and they can deliver perfectly-cut metal pieces in no time.

The present-day cutters are therefore more effective and precise when cutting through different metal types with different surfaces.

Precision In Cuts

The advanced method used in today’s cutters includes the use of high temperature based gas stream (ionized), which forms plasm arc to cut through metals. This arc formation ensures that the metal piece is cut with great precision every time the machine is used.

Not only can today’s cutters work effectively on thick metal pieces, but they can also efficiently give the desired shape to metal sheets. This is a huge advantage for artists and professionals who, earlier had to use cutter along with other tools to get desired shapes or sizes for their metal sheets.

Safety Tips

While using this metal cutting unit, you need to take a few safety measures, especially if you are new to cutting metals.

Prior to starting your metal cutting operation, conduct the following check:

  • Make sure that the compressed air is clean and free of oil or water, as the presence of any of these can wear out the consumable parts, and eventually other parts as well.
  • Check the air pressure and ensure that it is accurate.
  • Make sure that the connection is proper, as it will ensure better performance of the machine.
  • Ensure that the electrode and nozzle are in their proper place before starting your operation.
  • Handle Nozzle Carefully- Don’t allow the nozzle of the machine to touch your workpiece, especially if you are working on a current level that is 45 Amperes and above. If you allow this to happen, then the lifespan of the nozzle will be reduced due to double arcing. Another reason why double arcing occurs is because the unit is dragged against a metal template. As a result, the nozzle is also dragged, causing it to wear out prematurely.
  • Use Of Safety Gear- You need to follow the instruction manual carefully in order to understand how the machine works. Don’t forget to wear gloves and long sleeves before using the machine as molten metal produced during the process can injure your body. Also, make sure that you protect your eyes with welding shield or dark googles (with darkness shade ranging between #7 and #9) prior to beginning the process of metal cutting. And follow all the safety guideline and tips provided in the instruction manual.
  • Maximum Current- When you are setting up the machine, make sure that the current is kept at maximum output initially. You can turn down the current later on as required, but initially maximum current will help you get best results.
  • Direction To Maintain- In case you want to make a circular metal cut to get a round piece, you need to move in clockwise direction. Again, in case you don’t want to waste the remaining metal piece (From the circular cut), you need to move in a counter-clockwise direction. In order to get more precise and fine cut, you need to push your machine away from your body.
  • Ensuring Work Distance- While working with this machine, you need to keep a distance of 1/8 to 3/16 inch from the unit’s nozzle. Also, don’t move the cutter in upward-downward fashion and it will hinder the effort you put in to cut the metal.

Size And Noise

Most of today’s cutters are way more powerful than their predecessors, despite their small, compact size. They can be used to cut all kinds of materials and metals, right from 1inch metal plate to thin gauge sheets. While the traditional systems can cut through metals as thick as 2 inch or more, the ones mentioned in this review can efficiently deliver cuts on metals with a thickness under 2 inch.

The ergonomic design of the plasma cutters reviewed above ensure smaller but more portable size, which can effectively help you carry these heavy-duty machines all around your workplace conveniently and comfortably.

A big problem with such metal cutting machines is that they produce noise, not only physical but also electrical, the latter being caused by radiation of high frequency from within the system that interferes with the machine’s sensitive equipment.

However, we have listed out only the best cutters in the market that are mostly silent during operation, i.e. they don’t create any physical noise, and come with reduced electrical noise caused by high frequency. Therefore, you can rest assured that no matter what product you choose from our list of best plasma cutters, it will come in portable size and will be noise-free.

Design

The use of MOSFET and IGBT technologies ensure that the power supply remains constant and efficient during their operation so that the metal cuts are fine as well as precise. Also, the advanced Pilot Arc Technology ensures that metals with any kind of surface can be easily cut to get desired shape or size.

They are easily portable as well as lightweight. Ergonomic design and lightweight materials used in these metal cutting tools offer you the benefit of easily carrying around the unit wherever required.

They are extremely safe. The use of latest coolant system and in-built protection to prevent overheating contribute towards a safer and more secure operation.

Care And Maintenance

The only way to ensure great performance for a long time period you need to take care and maintain this advanced metal cutting machine.

Here are some effective ways to maintain and care for a plasma cutter:

  • Don’t Ignore Replacing Consumable Parts– It is crucial that you replace the cutter’s consumable parts as regularly as possible, or if absolutely required. This will prevent the other parts from being damaged because of the consumable parts.
  • Regular Cleaning- It is a must to clean the unit as frequently as possible. Make sure that you get rid of all signs of contamination and pollution as immediately as possible. The threads, both inside and outside, of the unit also must be cleaned (reserved crystal). You can use hydrogen peroxide to keep your unit dirt-free.
  • Ensure Proper Assembly- Another important point to note is that the only way to ensure a longer lifespan of the cutting machine is by assembling it properly. Also, follow the manufacturer’s guidelines for cleaning and maintaining the unit.
  • The Coolant And Gas Flow Should Be Appropriate– Make it your daily job to check the flow of gas and cooler pressure. Insufficient gas or coolant flow will lower the consumables’ lifespan, and will also affect the functioning of these parts. On the other hand, excessive gas pressure can result in hard starting.
  • Make Sure You Use Appropriate Parts– In case you use a wrong consumable part, chances are that the cut quality and performance of the cutter will suffer. Eventually, the unit’s lifespan will also lessen over time. That’s why you need to choose and use only the right parts for your cutter.

Warranty

When shopping for a plasma cutter you need to ensure that it comes with an outstanding warranty. There is no point in investing in a metal cutting machine that breaks within the first year of use but comes with only 6 months of warranty without covering your problem. Make sure that you read the product warranty thoroughly before purchasing it. Any model that comes with 3-year or longer period of warranty is worth your money.

FAQs

Why is it important to initiate an arc with sufficient air pressure?

The need for air pressure in plasma cutter is to ensure that the consumables are kept cool. If the arc is initiated without sufficient air pressure, it may cause the electrode to overheat, resulting in burning up of the tungsten in no time and eventually damaging the electrode.

Is it wise to keep the travel speed extremely slow during operation?

No, because if the travel speed is slow then the consumables can overheat, causing the parts to wear out prematurely. Make sure that the tool is moved at a proper speed, especially if the amperage is high.

How to prevent water from accumulating in the cutter’s air stream?

The presence of water in the unit’s air stream will suppress the electrical arc and the heat in the cutter. If you notice that the arc is unstable or erratic, then check for the presence of water in the system’s air stream. An effective way to dispose water off the system is by installing a proper desiccant system on your compressor, or by running a small-sized water separator (in-line disposable).
