For any manufacturing company to have at least a light-duty plasma cutting table is a must. Especially in emerging economies where resources are scarce, to have the right equipment, to fulfill all the production needs, is essential for efficiency.

Now, what is exactly a light-duty plasma cutting table? What power source is needed? What are the steps to take if you are trying to get your first cutting table? We will answer all these questions in this article, starting with how to classify plasma cutting tables.

How to classify plasma systems

In the welding world, there is a clear difference between the equipment and it can be easily classified as light, medium, or heavy duty. In that field, equipment below 250 amperes, is light-duty. Equipment between 250 and 425 amperes, would be medium duty. Any equipment above 425 amperes would be considered heavy duty.

Nevertheless, when it comes to plasma cutting, the differences are not so established. Even thought, the metal sheets size, material, and thickness can be key factors to differentiate automated plasma cutting in three big groups: light, medium, and heavy duty. Let’s take a brief look to these factors.

The size

Metal sheets may come in a variety of sizes. One of the most common is 48 x 120 inches. This might vary depending on the availability in the country.

Before to deciding on a plasma cutting table you need to consider the metal sheet size available and needed for your production. Make sure the plasma cutting table you are thinking on buying can handle the metal sheets you are going to cut.

The material

There is a wide range of metals that can be cut in a light-duty plasma cutting table. Basically, using plasma you can cut any electrically conductively metal. Both ferrous (meaning that contains iron) and non-ferrous metals can be cut using plasma. Some of the most common materials to cut in a light-duty plasma cutting table are:

  • Carbon steel
  • Mild steel
  • Stainless steel
  • Expanded steel
  • Copper
  • Brass
  • Aluminum

Chances are that the material you need to cut is among those. In particular the latter (aluminum) usually comes only in low thicknesses, so most likely you are going to use a light-duty plasma cutting table to handle that.

The thickness

Metal sheets and plates comes in a wide range of thicknesses. They can go from 0.02 inches (0.5 mm) to 6 inches (152 mm), even though these thicker metals are not so common. Usually, in fabrication, a metal plate is considered thick if is around 2-3 inches (51-76 mm). The rest are not common at all.

In any case, take into account the metal plate thickness you need to find out whether a light-duty plasma cutting table can do the job.

The cut quality

Another factor to take into account is the cutting quality. The more advanced cutting solutions would be able to provide a higher definition cut. So, if the workpieces are going to be cut in order to be weld, it is impotant an even cut, but high definition is not required. Now, if the cut is the final step, and is going to be exposed to the users, a higher definition is needed.

Finally, bear in mind that each cutting table can support some specific technologies. For example, you cannot expect that the simplest cutting table can be able to connect with the most advance power source, and achieve the highest cutting quality. Also, it would be a waste of money to get the more advanced cutting system to only perform basic cuts. So, your quality needs will also be key factors to define the adequate plasma cutting system for you.

The most reliable cutting process

Plasma cutting has never been easier

Hypertherm is the most reliable, easy to use, and durable plasma cutting equipment out there.

What would be a light-duty plasma cutting table?

A small dimensioned plasma cutting table of a few feet wide could be properly defined as light-duty. This could be the first plasma cutting table a company might buy. One example in this category would be the Extreme Practicut. This plasma cutting table comes in a variety of sizes, like 4×8, 8×4, and 5×10 feet. The effective work area in this table could be 2,500x 1,250; 1,250×2,500; or 1,500×3000 mm respectively.

The manufacturers who need to cut aluminum or stainless steel (which usually are the thinner metal sheets) might need one plasma system like this. The ideal thickness for this cutting bracket could be up to ½ inch.

Some companies have welding and cutting carriages, which can also be considered as a light-duty plasma cutting system. In these cases, a portable carriage can be used to handle the torch that will cut the workpieces, especially when the job must be done outdoors, like in shipyards.

The most common power source for these light-duty plasma cutting system could be one of the Hypertherm Powermax. There is a range within this series. Later in this article we will introduce the Hypertherm Powermax45 SYNC, which is widely used as a power source in some light-duty plasma cutting systems.

We will cover medium-duty and heavy-duty plasma cutting systems in other articles. Stay tuned.

Plasma cutting table or plasma cutting system?

When we mention “cutting table” we are referring only to the metallic, sturdy base where the cutting operations take place. The table may come with a bridge or it can be gantry style, in which case it would be only a two sides structure with a top. If you have a plasma cutting table,regardless of its size, you only have part of the solution.

A plasma cutting system refers to the complete solution to perform metal cutting operations. It includes the table, a power source, a CNC (Computer Numeric Control), some software to manage the CNC, the cutting torches, and other accessories needed to perform.

Now, a plasma cutting system is not just assembled randomly. An expert is required to define the right power source, plasma cutting table, CNC, and software so the system can serve the purpose for what is built. If done incorrectly, a failure is expected at any moment.

Whatever the case, before getting any equipment is essential that an expert can overview the whole plan, including the are where the plasma cutting system is going to be put within the building.

Extreme Practicut

The Extreme Practicut is a cutting table that is available in 3 sizes: 4×8; 8×4, and 5×10 ft. It is a double motorized system that guarantees a better quality cut. With its space to store water, it manages to keep the pieces at a perfect temperature.

The Extreme Practicut cutting table contains divided pieces that make it easy to collect the cut pieces. In addition, the hole at the bottom can be connected to a space allowed to dispose of waste in a non-polluting way.
