For a plasma cutter to be able to cut through any material, it has to be a good conductor of electricity, so using a plasma cutter is limited only to metals. However, new editions of plasma cutters can cut through almost anything, given that an electrical conductor is present. This is due to plasma cutters using a unique mechanism in creating plasma arcs.
Plasma cutters can cut through stainless steel and most plasma artists make metal flowers using propane tanks, as well as using sheet metal to create stairways.
If you wish to cut out a piece of sheet metal, you could imagine your plasma cutter to be a pencil and draw out any design of your choice. However, the downside here is that it cannot erase mistakes from plasma cutters, so there shouldn’t be room for mistakes.
Sketching out the design of your choice on the sheet is a great idea, as it makes room for lesser mistakes. Speaking of plasma cutters, you might be asking yourself what kind of metals can be cut with a plasma cutter?
Plasma cutters can cut through gold, copper, iron, aluminum, etc., as they are all good conductors. Irrespective of most of these metal materials being damage resistant, they cannot resist a sonic gas of over 50,000°.
Besides, there might not be any electrical conductor that could resist it. This is why a plasma cutter is considered a handy piece of equipment in today’s workshop.

How Do I Cut With Plasma Cutter
The capability of a plasma cutter cutting through any material all depends on the elements of the material in question. Material can be a conductor given that it’s derived from metal, making it the exact key point why metal is being used for electricity as it travels quickly through it.
For instance, your electrical cords consist of copper wire channeled through them. When they are plugged into power, electricity is being channeled through it to the other side.
Like a plasma cutter, a plasma cutter uses a special gas, along with compressed air. This creates a plasma reaction, giving it the power to cut right through any metal. But for this to happen, there should be an active connection of both positive and negative charges.
The metal that is being cut should be grounded by a clamp coming directly from the cutter. The connection is known to be positive, while on the other hand, the negative is the main cutter.
Hence, the connection is made, and the plasma can cut through the present piece of metal. Plasma is heated to maximize the flow of electrons towards a direction, while microscopic results suggest that it cuts its way through metal like warm butter being cut by a knife.
How Thick Metal Can You Cut With A Plasma Cutter?
It has been earlier proven that plasma cutting is vital against all types of conductors including alloy steels, copper, aluminum, etc. With the present plasma cutter in use, along with its capacity, as well as the present material to be cut through, it’s shown that between 0.5-180MM of thick metal can be pierced using a plasma cutter.
Plasma cutters are not to be competed with in terms of cutting through thick metals. Plasma cutters can be used to cut through regular thick steel of 40MM without alterations, especially when dealing with fragile pieces. Plasma cutters are also capable of cutting through structural steel of high strength because of their sonic speed of cutting as it’s also a crucial part of fabrication.
You should keep in mind that the included figures do not apply to all plasma cutters, and various manufacturers have different cutting capacities of materials to be used. For this particular reason, you should know what kind of usage the plasma cutter will serve before you proceed in purchasing a plasma cutter.
There are plasma cutters out there that can cut through 1.000 of mild steel and 0.7 of stainless steel sheet. The max thickness for aluminum is 0.7. However, higher capacities are being offered by most manufacturers. Hence, assuming that a system can satisfy everyone may not make a point.
How To Make Clean Cuts With A Plasma Cutter?
First things first, read the owner’s manual thoroughly to familiarize yourself with how safe to handle the plasma cutter. Doing that will give you a better knowledge of the plasma cutter’s capabilities and how best to make use of it.
Also, supporting your cutting hand with the non-cutting hand is a clever idea. Doing that makes the cutting hand steady enough, free to move to all angles, and maintains a particular standoff.
Speaking of making clean cuts, the travel speed of the plasma cutter should be the main concern. With a faster travel speed, mostly in aluminum, the cleaner cuts you get. When about to cut a thicker metal, the plasma cutter should be set to max output. While working on thinner metals, reduce the amperage to cut on a narrow line.
What Is The Difference Between A Clean Cut And Severance Cut?
The idea of a clean-cut is the plasma cutter cutting its way through the metal and both parts fall separately, leaving just a small strand at the bottom which can be easily cut off.
The marks will seem to be straight while starting, then it makes a slope at the end of the cut. The material shouldn’t require an extra touch for it to be welded back.
While a severance cut is when the plasma cutter is being used almost at its max capability. The cutting speed in severance cut should be a lot slower than that of clean-cut, and cleaning is required to be done at the bottom of the material.
