Q1 How to Choose the Right Plasma Cutter

The Thickness of the Material

The thickness of the material that you intend to cut should be considered. The rule of the thumb dictates that you should select a machine that has the cutting capacity of the material thickness you want to cut. Most of the time, you should consider choosing a tool that has more than 80% cut-capacity, especially when you are using a handled machine. It is possible to find plasma cutters that can fail to cut a particular thickness, especially when the cutting capacity falls below 75%. Mechanized plasma cutting machines have enough power to cut a thick material as compared to a manual device.

Cutting Quality

Cut quality is one of the most critical factors that you should consider every time you are buying a plasma cutter. Quality cutting has a significant impact on the quality of the finished product while at the same time impacting later stages of production. You want to get a well-cut piece that has smooth and clean edges. This will make sure that you don't spend much time preparing the same piece in the later stages of production. The smooth and clean cutting means that there is a narrower cut width, which means that there is less wasted material.


Reliability is another important consideration when you are purchasing plasma cutters. A reliable machine can easily be detected because it uses more software than hardware. Heating is a critical aspect of the cutting machine, which means that you should consider plasma cutting machines that have an effective cooling system. For example, a centralized fan that will help in bringing the air through the central system where heat-sensitive equipment is located. Continuous cooling will enable the system to perform excellently and higher reliability.

Look at the output power

The output power level (or amperage) of a plasma cutter indicates the thickness of the material you will be able to cut with it. Often, a plasma cutter will be rated on their amperage and you’ll be able to find out the optimal range of thickness that it will be able to cut.Make sure this thickness range aligns with the material you plan to cut most of the time. A good rule of thumb to keep in mind is that the thicker your material is, the greater the amperage you’ll need to be able to cut it.
Q2 How does a Plasma Cutter work?
Plasma cutting uses an electric arc and compressed air to cut steel, aluminum, and other conductive metals. There are two kinds of cuts you can achieve when using a plasma cutter: a clean cut or a sever cut.  A clean cut is a faster cut with a smooth finish. A sever cut is a rougher cut that takes longer and requires more clean-up. Clean-up may include grinding and chipping away at the rough edges. Typically, a clean cut is needed if you’re making yard art or cutting metal pieces to weld.  Whereas, a severed cut is sufficient if you’re simply scrapping metal.
Q3. How to selecting the right amperage for plasma cutting machine ?
A number one question I often get is "What's the thinnest material this metal can cut?" That of course to an experienced user of a plasma cutter is a relative question. In reality, any plasma cutter really has no bottom, or minimum thickness that it can cut. It's sort of like trying to define what the smallest fire a single match can set would be. In other words, every plasma cutter can cut through the thinnest metal sheet you could find. Not all would do it as well, though based off of the tip design and diamerter of the orifice in the tip. Some would leave a broader, wider kerf, others would look like a razor blade made the cut. It would depend upon the amperage used as well. Amperage control is key to giving the best quality cut on any given thickness of metal. But, at a point lowering the amperage, makes no economical or practical sense. Speed and quality have to be balanced. As amps are lowered, quality can go up, but speed can drop drastically. And at a certain point, quality begins to quickly drop when amps are lowered too far. There is a rule of thumb that I have come up with when using a plasma cutter to achieve the best cut. You won’t find it in any plasma cutting manuals though. I have found that 20 amps is truly the lowest practical limit for a plasma cutter. That amperage is good up to 1/8” of an inch.  After 1/8” you can typically add 10 amps for every additional 1/8” of cut. While this isn’t perfect for all conditions, it works well as a general guide. For 3/8” cut, 40 amps works out well for most brands of plasma cutters. For ½” cut, 50 amps works out well, etc. Keep in mind this isn’t the maximum thickness of cut that a plasma cutter is capable of cutting but rather, it is a good rule to follow for decent cutting speed and quality. For most torches, various tip sizes are available, each with its optimum cut range.
