Buyers guide to buy a plasma cutter

plasma cutter buying guide

Buying a plasma cutter can be challenging, even if you know all the plasma cutters on the market. Every plasma cutter is built for a special purpose and has its applications. If you know your required model, that’s great, and you can easily buy it.

But if you don’t, no worries. We have compiled a handsome piece of information to choose the best plasma cutter you need.

      Before buying a plasma cutter

As the market if full of plasma cutters with all the new emerging products, it is really hard to choose one. But many factors are involved in a plasma cutter’s performance and the things you must know before buying one.

Before buying a plasma cutter, you must know all the essential factors that you need to know. The following factors are the important points in a plasma cutter’s performance.

  • Power output 

The power of a plasma cutter plays a vital role while choosing a plasma cutter. The efficiency, thickness, and speed of a plasma cutter strongly depend upon power output. If you choose a plasma cutter of 12 amps from a 120V power source, it will cut a metal thickness of ⅛ inch. A plasma cutter of 60 amps from 230 volts cuts a thickness of ⅞ inches. So more the power of a plasma cutter, the higher the cutting thickness will be.

Moreover, the inverter-based plasma cutters offer more output power while being lightweight and portable.

  • Cutting speed 

Optimizing the cutting speed of a plasma cutter is important. This speed is measured in inches per minute IPM. The choice of plasma cutter speed depends upon your requirements, workflow, and amount of work done in an hour. A plasma cutter may cut a length in one minute, while others may cut the same length in four or five minutes, depending upon the cutter’s speed. Your choice of a cutting machine with good speed affects your productivity. So choose a plasma cutting machine according to the speed you require.

  • Duty cycle 

Knowing about the duty cycle of a plasma cutter is essential as it determines a plasma cutter’s efficiency. During a ten-minute operation of a plasma cutter, the amount of working time is the duty cycle of a plasma cutter. For example, if a plasma cutter works for five minutes before turning it off for cooling, the duty cycle is 50%.

When we run a plasma cutter at lower power, the duty cycle is more, but high heat dissipation may reduce the duty cycle. If you use the plasma cutter beyond the duty cycle, it reduces the torch life and overheats the machine.

Choosing a high duty cycle increases your productivity and helps in the long cutting process. If you choose a plasma cutter for industrial application, go for long-duty cycle plasma cutters. For small cuts and DIY  projects, a short cycle plasma would be an ideal choice.

  • The thickness of the material

You can use any plasma cutter to cut any thickness, but the quality of the cut and the efficiency of the cutter matter a lot. To have a tidy, neat, and professional cut, you need to buy the right kind of plasma cutter. All the plasma cutters go fine with thin materials, but in the case of thick material, the plasma cutter’s amperage should be high to have more power output.

A plasma cutter of the same amperage cuts the different maximum thicknesses for different metals. The expert’s advice is not to cut the thickness equal to or beyond the plasma cutter’s capacity; if you leave a tolerance between the limit and cutting capacity, the cutter’s lifespan increases.

  • Quality and finishing of the cut 

Almost all the plasma cutters offer the same cutting thickness, but the cut’s quality doesn’t need to be the same. If a low price plasma cutting machine cuts the same thickness as the high price plasma cutting machine, the user might think of the difference.

The low price plasma cutters don’t offer a high-quality cut and finish, and the final cut appears in poor quality cut and untidy finish.

Before deciding to buy a plasma cutter, make sure that you know about your requirement of the finish and cleanliness final cut. Even if your required cut is not for decorative purposes, a high-quality, clean-cut finish is the top priority in most cases.

  • Requirement

Highlight all of your requirements before you choose a plasma cutter. Think about the thickness, production per day, portable or bench item, material, industrial or domestic, professional or hobbyist. All of these factors narrow down to choose among the plasma cutters on the market.

  • Budget

If you know your requirements, you can easily decide your budget for the plasma cutting machine. Best plasma cutters for money are high ticket products and mostly used for professional purposes. On the other hand, a hobbyist can opt for the best budget plasma cutters available at low prices and can satisfy DIY projects’ requirements. A high-end product may look costly in the first place, but it saves a lot of time and effort.

 Types of Torches to consider

There are different types of torches for all the plasma cutters, but the torch’s purpose and working are almost the same. What makes a plasma cutter torch different from others are the following factors. One must know and consider all of these factors for the sake of high performance and productivity.

Lead:

Lead is an important element that attaches to the plasma cutting torch. One may think it just an ordinary cord that connects the plasma cutting machine with the torch, but it is not only this thing. It is much more than this because the length, durability, material, life span, and deterioration rate highly affect the cutting torch’s performance.

If you want a portable plasma machine and move around your object to have multiple cutting operations, you will need a long cord while keeping the plasma cutter safe. For this reason, you want to have a lengthy and durable lead.

On the other hand, when you work on a table, and all the cutting process goes on the table, you don’t need much longer lead, and even a small lead can facilitate your cutting process.

The quality of the lead material also has a significant impact on your plasma cutting experience. A high-quality lead increases productivity and eases the cutting process, while poor low quality, thin material just wastes time and may result in some dangerous and non-safe circumstances. Overheating of substandard lead material may lead to irreversible problems too.

Non-touch torch with High frequency:

The non-touch torch cuts the metal with the help of plasma technology. It does not touch the metal surface, and the high frequency creates the plasma that helps to make the cuts on metals from a distance. The amount of plasma and the distance are adjustable and can be changed depending upon the cut we need. The torch has a standoff feature that regulates and adjusts the distance between the torch and the metal surface.

The high-frequency non-touch torches are best for producing high-quality cuts with precision, consistency, and accuracy. Moreover, these torches’ efficiency can be enhanced by keeping the nozzle clean and tidy and safe from debris/dirt from the workpiece.

Drag technology

There are other kinds of torches that touch the workpiece surface during the cutting process. It happens because of the technology called drag technology. Drag technology helps the torch to drag on the surface and cuts the surface cleanly and smoothly.

If the drag technology does not work, the nozzle sticks to the metal surface because of the double arc fault. It results in poor, inconsistent, and jittery cuts having no precision and accuracy.

Moreover, the torch gets ruined, makes the workpiece untidy, and leaves dirty marks of irregular plasma on the workpiece.

The drag technology makes the intricate cutting patterns easy by eliminating this whole tiring cutting process. One can easily trace the lines and work on decorative and artistic cutting processes too.

Touch Start Technology:

The touch start technology is not a very common type, and usually, buyers don’t prefer it because it needs a lot of practice to master the cutting process. In this technique, the torch is first touched to the metal surface to create an arc to start the plasma. Then the torch is lifted off the workpiece, and the user slides the torch on the workpiece in a steady way to complete the cut.

As you need a handful of practice to get started with this technology and a steady hand is required to have clean and tidy cuts, it is harder than a non-touch torch and drag technology and is not recommended.

The touch start technology has the only advantage of low price and only people with low budget choose it.
