If you do not do any welding work before, you may not be familiar with a plasma cutter. So, before using it, you need to know what is a plasma cutter. Then you may want the details of this tool. However, It’s a fantastic tool to cut various types of metal that are electro-conductive.
From this brief, you may imagine which purposes plasma cutters are used. Basically, a plasma cutter creates ionized gas to cut the materials at high temperatures. The working mechanism of it is not so complicated. Before trying one, it is an excellent decision to learn all about this machine.
What is a plasma cutter
A plasma cutter is a beneficial tool for welding work. It helps you to cut metals like steel, copper, aluminum and some other electro-conductive metals. Generally, it works on ionized gas called plasma. It is for that this gas produces high-temperature with an arc. However, in the market, you will find many options for a plasma cutter.
Different types are for various purposes such as big or small projects, handheld cutters, small size cutters, etc. But for a home hobbyist or a small professional one, a handheld plasma cutter is good. Besides, automated cutters are for industrial uses. Moreover, some plasma cutters work through a robot or robotic arms to cut finely and small things. To get a handheld plasma cutter, you can visit handyman shops.
Why you need a plasma cutter?
We know that working with metals is not an easy job. If you need to make a hole or cut metal, you cannot do it with common tools. In this case, you need a special one. It is a unique tool for you to make your work easier. It helps you to do a quick and clean job.
So, for proper welding work, you obviously need a plasma cutter. But all are not the same at type and work. But to work with metal such as your steel fence, you need a cutter to cut down the bars. Though plasma cutter costs you, you should have one to finish your work with less effort but do it finely.
Benefits of using a plasma cutter
Plasma cutting or plasma cutter does a lot for us. For a welder or a hobbyist, it is a great tool. However, let’s know about some advantages of that.
You can use it easily
Plasma cutters are tools that are easy to use. They are so portable that you can quickly move them with hands. You can easily handle and work with this machine without any help from others. To know more click here.
Plasma cutters are versatile
You can use a plasma cutter on different metals. But only conductive metals are suitable for cutting with it such as steel, copper, aluminum, iron, etc. However, these metals are hard to cut with some other tools. With a plasma cutter, you also work with faster speed.
The cutting speed of a plasma cutter is better than some other cutting tools. So, when you compare it with others, you will see that a plasma cutter wins. It saves time and energy. So, when you compare with other cutting tools in the case of time, it will succeed. Obviously you can take a plasma cutter to save your time.
Great cutting quality
If an experienced one uses a plasma cutter with his steady hand, he can make a high clean cut. So, you can say accurate cutting with a plasma cutter is the most crucial advantage in the case of cutting angles, and various shapes with steel metal.
You can say that a plasma cutter is safe than any other cutting tool. The flame that comes out from the machine is not highly flammable. So, you can consider it more reliable.
How a plasma cutter works
Plasma cutters work with an electric arc that goes through gas and provides the hot temperature. This hot plasma can cut down the electrically conductive materials.
However, you will see the use of plasma cutters in automotive repair, salvage, welding work, industrial construction, etc. It is so popular due to its speed and accuracy of cut. The gas of the plasma cutter can make the temperature up to 30,000-degrees Celcius. So, it makes the plasma cutter special.
Basically, a plasma cutter creates electrical superheated ionized gas that cuts the metal body. It comes from compressed gas such as oxygen, inert gas, and some other gases. However, the machine blows the gas with high speed on the metal with a nozzle. Then an arc comes between the electrode near the metal piece and the nozzle. Thus, the gas gets ionized by the arc and melts the metal piece with high temperature.
However, you can effectively cut both thin and thick metals with a plasma cutter of different powers and speeds.
How to choose a plasma cutter
It is essential to consider some matters before choosing and buying anything. It is the same for a plasma cutter. There are many types of portable machines available in the market. So, before purchasing a plasma cutter, you need to be serious. Plasma cutter is beneficial in many ways such as easy to use, saves our time, cutting quality is excellent, etc. However, you should be careful about the matters below when you decide to purchase a plasma cutter.
Think about the thickness of your metal
Different plasma cutters come with different power. So, the source of the power of a plasma cutter decides its ability and efficiency. If your metal is ¼ inch thick, you can take a plasma cutter of lower amperage. And when you need to cut the material of ½ inch thick, you need a powerful one. If you use a plasma cutter of lower capacity to cut thicker metal, you will get poor cutting quality.
The duty cycle of the plasma cutter
The duty cycle means the time of a cutter that it can operate within a particular amount of time before cool off. So, a five-minute duty cycle means that this cutter can work continuously for five minutes before cool off. A lower-powered plasma cutter has an extended duty cycle. So, if you need a long or deep cut, the longer duty cycle is better for you.
The torch of a plasma cutter is another essential part. You should find two types of light of plasma cutters. Among the two, high-frequency torch is mostly used. This type of torch can create an arc with a high voltage transformer or capacitors. The main benefit of this torch is that you can work with it without moving any parts. Besides, it does not require regular maintenance.
The other option is contact start torch. It works based on the electrode of the nozzle to create a spark. Besides, you should look that your plasma cutter torch has a drag shield.
Make your budget
Before investing money to buy anything, it is essential to make a budget. It is right for your plasma cutter too. So, at first, select what type of plasma cutter is right for your work and then make a budget. It will help you to find out your desired one quickly.
Try your cutter before you buy it
Before purchasing a cutter, it is a good idea to try it. You can test some cuts with some of the cutters of the same rate and speed on the same thickness metals. Thus you can select which one is working well. For this, compare the cut quality and cutting time.
Besides, you can lift the plasma torch from the metal plate while cutting it. Notice from how far the torch works on the metal piece. Take the plasma cutter that can cut from an extended height.
Think about durability and portability
Both sustainability and portability are essential for a machine. We always want a durable one. Some tools come with protective cages that protect the parts of the cutters from a rough environment. Some contain air filters. However, air filters are essential to remove oil from the air.
A good plasma cutter needs portability. You need one that you can use one hand to use the cutter properly. Besides, if it is a lightweight one, you can carry it yourself anywhere you need.
The plasma cutter is an excellent choice for the welder and hobbyists. If you have any questions about what is a plasma cutter you can inform us. We will try to upgrade the information. Keep all the above information in your mind and then go to the market to buy a plasma cutter to make your job successful.
