What Is Plasma Cutter?
Essentially, plasma cutter is an advanced metal cutting tool that can cut through steel as well as other metals and materials. This cutting tool incorporates the use of inert gas that gets blown out from the cutter’s nozzle at extremely high speed for cutting the metal. Simultaneously, an arc (electrical) is also applied to this blown out inert gas, which converts the inert gas into plasm to form an extremely hot torch for cutting through any metal very conveniently and comfortably. Today’s plasma cutter ideas include several technologically advanced parts to ensure that you get the best results when cutting metals with these tools.

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
- 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
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:
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.

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:
Safety Tips
While using this metal cutting unit, you need to take a few safety measures, especially if you are new to cutting metals.
- 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
The two important aspects of a plasma cutter that affect their overall performance are: 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
As far as the design of this advanced metal cutting machine is concerned, it should be clear from the reviews that most of today’s plasma cutter designs include the following common aspects: 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.
- 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.
