Factors to Consider When Purchasing the Best Plasma Cutters 

There are many plasma cutters in the market from different manufactures but you need to choose the best. It may not be easy to pick the right one unless you know what to look for. We have compiled a list of the factors to consider for you to choose what suits your needs and situation. Read on:

  • The stability of the tool

The stability of the cutting surface is crucial when it comes to choosing the best tool. The table should be fully-welded and rock solid and should not twist or move when you start cutting. The machine that you choose must be able to withstand huge pieces of metal every day and not one the breaks down after only a few days of using. The machine must, therefore, be uniquely designed to be a heavy-duty and not weak one. 

  • Must be easy to use

For your machine to be productive, it must be easy to use. It should have software that is not too hard to operate as this will affect your speed of production. The machine should be of high quality with excellent software that will enable you to enjoy the capabilities of the tool. It is advisable to look for a device whose operation is easy to learn and also one that includes a user guide and instructions.

  • Must be durable

Since these tools are meant to serve you for long, you should look for one that is sturdy and durable. It is crucial that you look for a machine that will maintain its effectiveness even after many years of service. To be sure, you can search from the internet or inquire from others who may have used the machine ahead of you. Different brands have their unique qualities of strength and you will, therefore, need to search extensively. 

  • The speed

The speed of a machine is one of the determinants of superior quality. It is, therefore, necessary for you to look for a tool whose speed is high as this will translate to the production. The high speed of a device means higher production and thus the low cost of operation. You should, therefore, look for a machine whose rate is up to 500 IPM (inches per minute) but this depends on the materials to be cut. 

  • Accuracy / Precision

Accuracy or precision is a key factor in every process whose outcome must be appealing and attractive. You should make sure that besides the machine having the right speed it produces accurate cuts with the best quality.  The cuts must be clean and sharp to enable them to stand out among those of your competitors. 

  • The cost

 Your budget plays a major role that may out shadow all other factors. The quality of the plasma cutter may be directly proportional to the cost. You need to choose the highest quality machine that does not call for repairs after every few cuts. It will be wise therefore that after establishing what suits your needs, that you save enough money to buy the tool. It may however not be the case that the most expensive tool is the best, therefore, shop and compare several and choose the most superior. 

  • Compactness

The tool that you select must be compact and lightweight for you to move it, especially if it requires you working from different locations. It should also be capable of cutting different materials such as aluminum, carbon steel, stainless steel, among others, easily without leaving spot welds on the product. It is also necessary to look for a tool that has fans to regulate the temperatures to cool off the machine and extend its life. 

  • The type of projects you are dealing with

The type of projects or tasks you are dealing with also plays a crucial role in choosing the tool to purchase. If you only deal with minor welding works or repairs, you don’t need to buy a very complicated tool. However, if you are working on massive projects such as automotive assembling and construction work, you will require a huge machine that can cut through heavier metals.

Frequently asked questions about best plasma cutters

Like all other people that work with metals, you may have several questions that you need to be answered about plasma cutters. We have sampled some of them and their answers which we feel are important to you.

Q. What is a plasma cutter? 

A plasma cutter is a machine used to cut through electrically conductive materials such as aluminum, copper, steel among others using an electrically ionized gas. The tool cuts by a means of an accelerated jet of hot plasma using a torch to transfer energy from a power supply to any conductor, resulting in a cleaner, quicker cutting process. A gas such as a shop air, nitrogen, oxygen, or argon is forced through a small orifice inside the torch.  An electric arc generated from an external power source is introduced to the high pressured gas flow, which results in a plasma.

Q. What are the benefits of plasma cutting?

The process is less expensive than both laser and water jet cutting and hence cost-effective. This method prevents warping and damage of paints and other coatings since it keeps the materials cool in spite of operating at high temperatures. 

Q. What is a high definition plasma?

This is plasma cutting in which the beam is distributed through a much smaller nozzle orifice at a higher speed. The high-velocity results in more accurate profile cutting. The beam is constricted using a shielding gas that swirls around it hence keeping the beam straight. A square edge on the cut parts and better cut surface quality are produced as a result. This process may be different from plasma cutting as the speed must be higher.

Q. Which plasma gas gives the best result with mild steel?

Most economical cutting use dry shop air to cut mild steel, aluminum, and stainless steel. However, if the material is thick aluminum or stainless steel, argon-hydrogen with nitrogen secondary is the ideal choice. But the system must be properly equipped for safe operation with argon-hydrogen gas. You, therefore, need to understand all the requirements of plasma cutting before using it.

Q. Must you have an air compressor for a plasma cutter? 

An air compressor is necessary when using a plasma cutter. If you are cutting steel as a hobby, you will need a compressor that has a CFM rating greater than that of the tool. However, if you are dealing with heavier cutting, the compressor should be either 1.5 or 2 times greater. It is therefore advisable to check on the manufacturer’s manual to know the requirements of your machine and use it with the appropriate air compressor. 

Q. Can a plasma cutter be used as welding equipment? 

If the cutter uses oxygen, it can cause oxidation of the aluminum metal and is therefore not ideal. However, if you have the right design of the torch a less expensive nitrogen-water injection can work well with the cutter. It can be used for cutting and subsequent welding of aluminum and stainless material. 

How to use a Plasma cutter
