How To Make Plasma Cutter

How is a plasma cutter made?

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.

Can you convert a welder to a plasma cutter?

A MIG welder can be used as a plasma cutter. You’ll need an air compressor and carbon electrode in place of wire along with a number of small items. Keep the amperage between 25 and 50 and increase the wire feed speed.

How much does it cost to make a plasma cutter?

Depending on type, size, and features, a CNC plasma cutting machine could range anywhere from $15,000 to $300,000. That’s a big range, but the vast majority of CNC plasma machines sold today are well below the $100,000 mark.

What is needed for plasma cutting?

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.

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 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 can a 30 amp plasma cutter cut?

Designed for portable repair work and small business project use, CUT-30 Plasma Cutter cuts a thickness of 3/8 in., and the max severance thickness is 1/2 in., Specifications: Type: DC Air Plasma Cutter, Supply Power: 115V/230V/60Hz/1-Phase, Rated Input Current: AC-115V/30A & AC-230V/15A, Cutter Current Range: AC-115V.

Does Plasma cutters use gas?

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. etc. The gas is also directed around the perimeter of the cutting area to shield the cut.

Can I run my plasma cutter on a generator?

Of all the plasma cutters in the industry, only the Spectrum 375 CutMate™, Spectrum 2050 and Spectrum 3080 plasma cutters consistently cut steel at or greater than 3/8 in. when using generator power. When connected to a generator with at least 8 kW of power, such as the Bobcat 225 NT, it cuts steel up to 5/8 in.

Are plasma cutters worth it?

Plasma cutters also cut quickly and efficiently. Plasma equipment is considered to be better value for money, as well. Plasma torches are low-maintenance, rarely requiring replacement. Plasma cutting also relies on inert gases, making it much safer to use than oxygen-based cutting.

Does a plasma cutter need air?

All plasma manufacturers include minimum air flow and pressure requirements for an air compressor in the owner’s manual. These requirements differ between systems, but as an example, an air compressor for a plasma cutter like the Hypertherm Powermax45® requires 6 cubic feet per minute (cfm) at 90 psi.

Is it expensive to run a plasma cutter?

Low Operating Costs CNC Plasma cutters tend to cost around $15/hour to maintain. CNC Lasers are just slightly higher at $20/hour. And CNC waterjets usually come in at the most expensive – $30/hour.

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.

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 a plasma cutter cut aluminum?

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 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 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.

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.

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.

Will a plasma cutter cut rusty metal?

Plasma can cut any electrically conductive metal including stainless steel, mild steel, aluminum and more, without pre-heating. Plasma is also great at cutting painted, dirty or even rusted metal.
