How Do Plasma Cutters Work

Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening. The gas can be shop air, nitrogen, argon, oxygen. This high speed gas cuts through the molten metal. The gas is also directed around the perimeter of the cutting area to shield the cut.

Can a plasma cutter cut anything?

Typical materials that can be cut with a plasma torch are steel, stainless steel, aluminium, brass, copper and other conductive metals. Plasma cutting is widely used in manufacturing, automotive repair and restoration, industrial construction, salvage and scrapping.

Do Plasma cutters use electricity?

Plasma looks and behaves like a high-temperature gas, but with an important difference: It conducts electricity and cuts any electrically conductive metal. The plasma arc results from electrically heating a gas, typically air, to a very high temperature.

Do all plasma cutters need air compressor?

Plasma cutters need air pressure to cut in a two-stage process. Therefore, all plasma cutters need an air compressor to generate enough air pressure for the task. If you buy a plasma cutter without a built-in source of air, you’ll need a separate air compressor.

Can you plasma cut without gas?

Do you need gas for a Plasma Cutter? Gas is needed for a plasma cutter in order for it to work and create the plasma. As mentioned, the most popular gases to use are oxygen, nitrogen or argon.

Can you stick weld with a plasma cutter?

With the right torch design, a nitrogen-water injection, less expensive than other gases, can work well when plasma cutting aluminum and stainless material for subsequent welding. The process involves an electrode surrounded by nitrogen, which is heated by an electric arc to form the plasma.

Will a plasma cutter cut rock?

Plasma-jet 24 is initially directed at the rock face 12 until a portion of the rock is melted to form a molten film 80. The electrical conductivity of this molten rock is higher than that of the solid rock. The high velocity jet 24 from torch 20 blows away material and thus enhances the rock cutting.

How thick of metal can a 50 amp plasma cutter cut?

Excellent Air Plasma Cutter: The Cut-50 Plasma Cutter can easily cut up to 0.55”(14 mm) metal under maximum output with ultimate portability weighing only 21.56 lbs.

Can you cut wood with a plasma cutter?

Virtually any metal can be plasma cut including steel, stainless steel, aluminum, brass, copper, etc. Plastics and wood are not electrically conductive and cannot be plasma cut. However, you can use a rotary saw, router, or other tool if you want to cut these materials in the PlasmaCAM machine.

Can a plasma cutter cut titanium?

Plasma Cutting for Titanium Titanium can also be cut using a plasma torch or plasma CNC machine. Plasma cutting is extremely versatile, and can be especially useful for hard-to-reach angles or parts that do easily not fit on a bench or on a CNC bed.

Can plasma cutter cut cast iron?

The more energy added via the plasma cutter, the hotter the plasma arc becomes, providing more cutting capacity and efficiency. One of plasma’s greatest advantages is its ability to cut non-ferrous metals such as aluminum, stainless steel and cast iron, materials that are becoming more common in many applications.

Can a plasma cutter hurt you?

The plasma cutting arc blows out hot metal and sparks, especially during the initial piercing of the metal. It also heats the workpiece and cutting torch, all of which can cause fire and burns. To protect your eyes while plasma cutting, wear approved safety glasses with side shield.

Can I use compressed air for plasma cutter?

If you plan to use your plasma cutter for hobby projects or for cutting an occasional piece of steel, then an air compressor for your plasma cutter with a cfm rating slightly higher than the minimum requirement listed in your owner’s manual will likely be adequate.

What gas is used in plasma cutting?

Compressed Air is the most commonly used gas for lower current plasma cutting and works well for most metals from gauge thickness to 1 inch. It leaves an oxidized cut surface. Compressed air can also be used for plasma gouging on carbon steel.

How much PSI does a plasma cutter need?

For the majority of the Everlast product line, air pressure required to operate the torches is anywhere between 55 to 70 psi. Low amperage cuts will require less air pressure for more stable operation, sometimes down to 45 psi or so, or the arc will be blown out.

How hot is plasma arc?

The energy of the plasma jet and thus the temperature depends upon the electrical power employed to create arc plasma. A typical value of temperature obtained in a plasma jet torch is on the order of 28000 °C (50000 °F), compared to about 5500 °C (10000 °F) in ordinary electric welding arc.

Can you cut stainless with a plasma cutter?

The plasma cutting process may be used to cut any conductive material, including carbon steels, stainless steels, aluminum, copper, brass, cast metals, and exotic alloys.

Can I use oxygen for plasma cutter?

Oxygen. Using oxygen in your plasma torch offers the fastest cutting speed compared to any other plasma gas while still offering the best cut quality. Oxygen can also be used on stainless steel and aluminum, but it produces a rougher cut surface.

Can you weld aluminum with a plasma cutter?

Plasma cutting aluminum can create perfect welds. By using such a cutter, you can keep the surface of the metal outside the welding area moderately cool. Plasma cutters accurately and quickly weld aluminum workpieces together.

Can you use a TIG torch as plasma cutter?

Yes you can actually do some decent metal cutting with a tig machine on certain types of thin sheet metal. ..but NO it wont be as good as a plasma cutter. I have found that the more amperage used the faster and better the cut.but 200 amps will work ok too if thats all you have.

Is plasma cutting welding?

Plasma cutting actually originated from plasma welding, a unique welding sub-type that uses electrically ionized gas (plasma) to fuse two metals together. By increasing the plasma discharge, you’re able the transform the electronic welder into a cutter. Before plasma is generated, a starting arc must first be created.

What can plasma not cut?

Other materials that cannot be cut include glass, concrete, and ceramics. These materials are non-conductive and are used to insulate electrical products. If you are using a plasma cutter, it simply needs to have a conductivity to complete the electrical connection. Otherwise, it just won’t cut at all.

Can you cut copper sheet with a plasma cutter?

Plasma cutters offer flexibility to cut most types of metal in varying thicknesses, including steel, stainless, aluminum, copper, bronze, brass, titanium, Inconel and other materials.
