Buying Guide

What Is a Plasma Cutter?

A plasma cutter is a cutting tool that uses hot plasma to cut through metals. A cutter works for metal fabrication needs, and it can also work for construction and manufacturing purposes.

How Does a Plasma Cutter Work?

A few steps are necessary for getting a plasma cutter to function:

  1. An electric arc travels through gas inside an opening on the cutter. The gas may consist of oxygen, argon, or nitrogen.
  2. The gas warms to where it reaches a plasma state. Plasma is considered to be the fourth state of matter that is different from a solid, liquid, or gas form. Plasma is hot enough to where it can cut through metal.
  3. The plasma triggers the arc to push the gas through to start cutting metal. The plasma is electrically conductive. The opening on the cutter will prompt the gas to move by fast, thus allowing the gas to cut through the metal. The metal will be heated up as the plasma moves through, thus producing a clean cut.
  4. The gas also moves along the outside parts of the cutting area to protect the quality of the cut.

Why Should You Use a Plasma Cutter?

The reasons for using a plasma cutter are plentiful:

  • The edges on the metal you cut will be smooth.
  • You can cut metal to make it fit into many installations or other applications.
  • A plasma cutter can produce intricate and detailed designs on any metal you use.
  • A cutter can also perform repeated cuts for manufacturing purposes in moments.
  • A plasma cutter will not leave behind as much debris as what you’d get out of something else.

What Can You Cut With a Plasma Cutter?

You can cut various metals with a plasma cutter. A cutter is useful for traditional sheet metal and aluminum. You can also use your cutter on copper, brass, and other hard metals.

How to Tell the Difference Between Different Plasma Cutters?

There are a few things to note when looking at plasma cutters:

1. Severance Capacity

The severance capacity of the cutter is the maximum thickness that the machine can cut. Some units may also come with a clean cut-rate based on the thickest material that a clean-cut can work Check on how well your model works based on what you need to cut and how thick the material can be before starting.

The severance capacity is not to be confused with the clean cut-rate. While a severance capacity rate states that you can cut through thick materials, it may still entail a few rough or grooved surfaces. A clean-cut measurement refers to how something can be clean and cut through without any jagged features or other items possibly coming about.

2. Cutting Rate

Some machines can cut a certain amount of metal in a brief period. The cutting rate may be measured based on how much metal at the half an inch thick can be cut in a minute.

3. 2D or 3D

A two-dimensional cutter will produce cuts on flat metal. A three-dimensional model can operate at any degree and can produce curves while cutting.

Which Type of Cutter Is Right For You?

You’ll have to find a cutter based on how thick your metal is, how much metal you need to handle at a time and whether you need cuts at specific angles.

A top-grade cutter can cut half-inch thick metals without concern. It may also help you with your 3D cutting needs. But it might be tough to cut through metals close to an inch thick.

Be sure to consider what you need out of a cutter before you make your final choice. Don’t forget to consider possible expansion efforts. You might need a cutter slightly more effective or heavy-duty than what you need to make up for any issues.

Key Features To Find In Your Cutter

Be sure to look at the following points when finding the best plasma cutter for your use:

  1. Review the maximum cutting thickness on your cutter to see how well it can function.
  2. Take note of how well you can get the cutter to start working. The cutter should handle its energy supply well.
  3. See how well the cutter can handle the heat it produces. The energy should be easy to distribute without potentially harming the machine.
  4. Any displays, gauges, or other control or diagnostic features would help.
  5. Many plasma cutters are light in weight. See that you can carry and transport your cutter well.
  6. Look at the air requirement in your cutter. The need is a measure of how well your cutter can take in air. The cutter must bring in enough air pressure to ensure it stays functional.

Safety Considerations

Regardless of the plasma cutter model you use, you must ensure you have the proper safety equipment on hand. You will need safety goggles that can protect your eyes from the UV rays that the cutter may product, not to mention any particles that might fly around when cutting.

You will also require other protective forms of clothing, particularly gloves. Hearing protection is also recommended, as some cutters may be very loud.

Conclusion

You’ll have to look at how well a plasma cutter can work for your machining or manufacturing needs. A plasma cutter can be very convenient, but it has to work out well. You need a cutter that is easy to handle and use, not to mention something that can move through the metal you’re trying to support. The design of your cutter can also make a difference in how well you’re going to get the work that you need to complete done right.

The features of each cutter on today’s market can be complex and tough to figure. Knowing what works in a cutter and understanding what you plan on using a cutter is essential to your success when getting such a unit ready for your convenience.
