What Is Plasma Cutting?

Plasma cutting is the process of cutting through materials that are conductors of electricity. This process is carried out by an accelerated jet of hot plasma. The plasma cutting process is usually used for aluminum, iron, brass, stainless steel and copper.

The process of plasma cutting is a widely used process due to its efficiency and effectiveness. Plasma cutting is done by industries of various sizes as well as individuals who have a need to cut through metals. If you are into the construction business, you have likely seen plasma cutters put to work.

Plasma cutting is favored because it is done by a machine thus eliminating any possible errors that cutting by hand could have caused. Plasma cutters are also fast. They are the best option for cutting through metals of larger numbers because of how little time it will take. In addition, they are not too pricey and so they will make a great addition to any business.

 

What is a Plasma Cutting Machine/ Plasma Cutter?

A simple way to define plasma would be to refer to it as the fourth state of matter. If a solid (metal, ice, etc.) is heated, it changes to water. If it is heated further, it will change to steam or gas. However, if it is heated more, it will become a conductor of electricity which has been named plasma.

A plasma cutter is a machine that transfers energy through the electrically conductive gas from any power supply to an electrically conductive material.

 

Plasma Cutting Process

This process is carried out when an electrical beam that has been formed of electronically ionized heated gas cuts through a material by completing an electrical circuit. Through the use of a ground clamp, the circuit is completed. The plasma is created by squeezing gasses tightly together. The compressed gas is blown out through a nozzle designed for it.

As the gas is blown out to the material, an electrical arm is created in the gas. An electrode then connects to the material meant to be cut.

The electrical arc which is formed ionizes the gas. Due to that process, plasma is formed. The formed plasma applies extreme heat on the material, thereby melting it. The whole process is neat, clean, sharp, and fast.

 

What to Consider Before Picking Out a Plasma Cutter

If you are out to get the best and affordable plasma cutter available, you will need to consider some things. Goo budget plasma cutters are not a far cry from the expensive ones. The good budget types only take out some things from the expensive ones that will still make them good choices. Decide what you need in a plasma cutter and then, search for one that meets your specifications. While you may not get one that has everything you want, if you use this guide, you are sure to get a plasma cutter with specifications that are very close to those you desire. Before picking out a plasma cutter, you will need to consider the following:

Duty Cycle

When deciding on a plasma cutter to buy, it is imperative that you consider the duty cycle of the plasma cutter. A plasma cutters duty cycle refers to the machines ability to work on a particular weight of workload for a period of time.

Some plasma cutters are designed to be used for shorter periods than others. During their time of use, they maximize their output with the power on ground. During the period of time, their performance is very high and top-rated.  However, that level of performance is due to the fact that that they maximize the power levels available at a go. If you were to extend their working period, their delivery levels would drop. They would not be able to carry out such levels of use. They would not perform the same way as they would if they were working for longer periods and on heavier duties.

One of the easiest ways to know a plasma cutter with high duty cycles is through their amperage. The length of their duty circle is detected by how high or low it is. That is, a higher amperage translates to a higher duty cycle and a lower amperage, to a lower duty cycle.

Also, you need to consider the thickness it can cut averagely. Most units can make up to a ¼ cut. However, if you push your machine to reach its maximum cut unit, it will have a negative effect on the material to be cut. It is best to stay well within the machines cut capacity to enjoy precision and neatness on your material’s cuts. Do not overlook its cut capacity if you want a machine with a high duty cycle.

A machine with a low duty cycle will only perform well for a shorter period. After this, performance will reduce which will cause the job to take longer. When picking out a plasma cutter, ensure to consider the duty cycle to avoid future problems and to ensure you get your money’s worth.

Start-Up Mode

Plasma cutting machines can be classified into two based on their modes of start-up. They are classified into contact and frequency.

Cutters that require frequency start-ups are better of use in places which do not have other electronic devices that are sensitive to frequency such as analytical equipment, radios, and computers. If your cutter is placed near these types of materials, the frequency signal may disrupt their working.

If your work includes such equipment, get a plasma cutter that requires contact to startup.

Electrical Outlets

You do not want to purchase a machine which you have no means of powering. Prior to purchase, ensure that your preplanned location to use the plasma cutter has an outlet that can power it. You will need either 110v or 220v outlets. You should also check your circuit breakers to be sure that your amps can withstand not only the processors but also the amperage of your machines unit.

Another important feature to consider is the input voltage of the unit. Most cutters are either 120 or 220 volts. Some units are capable of working with either. If you have a 220 volts outlet, you need a plasma cutter that can handle higher voltages. If you have a 120 volts outlet, you are better off with a lower cutter. You will also need to install a 20A circuit put in where your plasma cutter is to be.

Before buying, make sure that your workshop has suitable outlets. Most residential buildings have outlets with 15A breakers. That will not work for you if your cutter is a high amperage consumer. You should ensure that your breakers have sufficient amps to withstand the amperage of the unit and the compressors.

Price

Before buying anything, you need to determine how much you are willing to pay for it. An affordable plasma cutter can fall anywhere between $250 and $600. However, it is important to note that the price of an object does not dictate the quality. This is why it is extremely important to make suitable research before deciding on a plasma cutter to buy. If you are looking for cutters with higher capabilities, you can expect to spend even higher.

Some extremely cheap cutters are priced so ridiculously because they have reduced performance. Although price is not an indication of performance, it is better to steer of ridiculously priced goods. While you should have a price set in your mind, you should be flexible enough to add a few dollars to it in case your perfect machine is a bit higher than your original budget.

If you are trying to get your first plasma cutter and do not have much experience, you would be better off with a durable and multipurpose machine. A heavy-duty machine is better suited for professionals and other users who envisage high usage. Choosing a durable machine is not only cost-efficient but is also great for long-term use.

 

Mobility

Sometimes, you will need to make use of your machine in a different location. For many possible reasons, you may need to convey your machine to another location. For this reason, whatever plasma cutter you may buy must be portable and mobile.

For one thing, the machine must not be too heavy. If you are sure that you will be moving your plasma cutter around, decide on the maximum weight whatever mode of transportation you have is capable of carrying. You do not want something heavier than you can transport. A nice feature your plasma cutter may have is one that will make carrying convenient such as straps, wheels, or handles.

Mode of Air Supply

When purchasing a cutter, you should carefully consider the mode of air supply. Plasma cutters make use of forced air. The modes, however, differ based on various things. It is very common for the cutter to have its own air compressor. However, if you are going for a more affordable unit, it may not have one meaning you will have to get an air compressor separately. If you o not have one at hand, you will be better off getting a cutter that complete.

Average Cut Thickness

Decide on the amount of cut capacity you need. This depends on the materials you intend on cutting. If you intend on cutting regular metal or aluminum sheets, you can be satisfied with a unit of ½ cutting thickness. The ability of your machine greatly affects the speed.

The speed at which your plasma cutter carries out its duties is very important. If you plan on cutting thick sheets, it is important that your cutter can cut through them while optimizing time. As you approach the maximum thickness rating of your cutter, your cutter will have to proceed slower than before. If you reach try to cut a material that reaches the maximum thickness rating of your unit or comes too close to it, you are likely to have slow jobs which are not even smooth. Before buying a cutter, decide what sort of materials you will be cutting.

Find out the maximum thickness of the possible materials and purchase a plasma cutter that can cut materials a little bit thicker than that. Cutting materials that push your machine’s limit is never a good idea as your materials will not be smooth or neat.

Versatility

Some plasma cutters also work as welding machines. If you require a welding machine, it is a good idea to look for a machine that can also weld as well as function as a plasma cutter. If you are getting such a machine, ensure that you get one of the best welding gloves to ensure safety.

Consumables

When picking out a plasma cutter, you have to ensure that you can utilize consumables while being cost-conscious. If you pick out a low-quality plasma cutter, you will use more consumables. When picking out plasma cutters, realize that inexpensive does not mean low-quality.

Most plasma cutters make use of a system containing 5 consumables: The swirls ring, a single electrode, the shield, the nozzle, and the retaining cap. Each consumable works hand in hand with the others to ensure smoothness, neatness, and precision.

The swirls rings act as the directors or guides. It directs the gas in the various needed directions. It monitors the movements from the machine to the torch. Due to its guidance, it prevents the nozzle from burn damage.

The electrode which is the next consumable is usually made of copper. It is the conductor of the current. The current is conducted by the electrode to the plate from the torch. It then completes the circuit.

Shields are known for protection and this is no different. The shield ‘shields’ all the other consumables. They need to be protected from sparks and heated metal. Drag shields are great for novices.

The retaining cap ‘retains’ the consumables together. It holds the swirls ring, a single electrode, the shield, the nozzle, and the retaining cap. This allows them to function properly.

The nozzle directs the plasma arc. It is in charge of the focus. The orifices play a role in the focusing of the arc. Smaller orifices produce smaller and neater cuts.
