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.
Do you need an air compressor for a plasma cutter?
But if you do a lot of cutting, or plan to cut thick plate, we recommend using a compressor that is 1.5 to 2 times the plasma system requirement. Beyond choosing the right size air compressor for your plasma cutter, it is critical that you ensure the air that reaches your plasma cutter is high quality air.
Do you need gas to run 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. Nitrogen is the best choice when it comes to cutting aluminium and stainless steel and it can provide an excellent cut quality.
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.
Is plasma cutting AC or DC?
These system components provide the electrical energy, ionization capability and process control that is necessary to produce high quality, highly productive cuts on a variety of different materials. The power supply is a constant current DC power source.
Can a plasma cutter cut wood?
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.
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.
Is a plasma cutter better than a torch?
Plasma does not require the metal to be preheated before cutting, which saves time, and plasma cutters also outperform oxy-fuel torches when cutting stacked metals. Faster speeds can be achieved on thinner metals with plasma, with minimal or no metal distortion.
Can you weld with 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.
Do Plasma cutters use air?
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 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.
Do you need oxygen for a plasma cutter?
The most common plasma cutter gases include air, hydrogen, oxygen, nitrogen, and argon. All five of these work relatively well on thinner sheets of metal, one-half inch or less, but when the plate thickness increases, fabricators typically use a combination of these gases to improve production.
Can you plasma cut Aluminium?
Plasma cutting can be performed on any type of conductive metal – mild steel, aluminum and stainless are some examples. Plasma cutting, however, does not rely on oxidation to work, and thus it can cut aluminum, stainless and any other conductive material.
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 a plasma cutter cut through concrete?
An experimental investigation of heat propagation in the case of plasma cutting of concrete is reported. For a mean power level of 11.2 kW and a nitrogen gas flow rate of 25 Nl/min, the torch is able to cut a concrete plate of 52 mm in thickness with a speed of 20 mm/min and a whole efficiency of about 30%.
How many volts is a plasma cutter?
Primary power Plasma cutting requires two basic elements — air and electricity — so the next question to ask is what type of input power is available. Several 30-amp plasma cutters, such as the Spectrum® 375 X-TREME™, operate using 120- or 240-volt power.
What are the two types of plasma cutters?
What Are the Different Types of Plasma Cutters Used on CNC Tables? Air Plasma. Air plasma tables are ideal for low-volume manufacturing and are often used on entry level steel fabrication machines. Oxygen Plasma. High-Definition Plasma. CNC Plasma Cutters. The Leader in Automated CNC Plasma Cutting Machines.
What are plasma cutter electrodes made of?
The electrode is usually made of copper, but with a metal insert at the point where the arc attaches. That’s because the copper would melt too fast if the arc attached directly to it. Tungsten makes a great electrode material, so lots of electrodes have a tungsten insert.
Why does my plasma cutter keeps cutting out?
Too slow of travel speed when cutting- Moving excessively slow when cutting (especially at higher amps) overheats the torch consumables and can cause the parts to wear out prematurely. It can also cause the arc to terminate. 3. Dragging the Torch Nozzle on work piece- This is a common mistake beginners make.
What is the difference between a laser cutter and a plasma cutter?
Laser cutting is a precise thermal cutting process, utilizing a focused beam of light. Plasma cutting, on the other hand, uses a mixture of gases in order to form a cut. With our high definition plasma cutting equipment, we are able to perform bevel cuts on parts as required.
Can you make money with a plasma cutter?
Plasma tables are able to cut materials much differently than a CNC mill. “Everyone loves something ‘cut in metal’. It is substantial and permanent,” he says. Sign making is a pretty basic business, and you can provide products to your customers at fairly reasonable prices while still making a profit.
