Part 1: Why Do You Need an Air Compressor for Plasma Cutter?

Having an air compressor for plasma cutter is compulsory, which is indispensable for perfect performance of the device. Without the gas, your plasma cutter simply will not function. Here’s why:

• Air Pressure for Cutting: These compressed air powered plasma cutters are designed to use the plasma arc to sever different materials. The compressor supplies pressured air that the cutter transmits to the plasma arc.
• Cooling and Shielding: Compressed air is not only serving as the plasma arc source, but also cooling the cutting torch. Jet air cleans away the molten metal and garbage at high speed, thus ensuring the cleanness of the torch and neat tracks. Likewise, the bubble of air reduces the interference from the atmosphere.
• Consistency and Precision: The plasma-arc stability and precision are based on an uninterrupted compressed air supply. The change in air pressure restricts the cutting process to be uneven or cut out.
• Versatility: An air compressor, which enables you to tune the air pressure to the thickness and type of material you’re cutting, is necessary. Such versatility allows you to achieve perfect cutting for any application.
• Efficiency: The function of a compressor is to supply a constant stream of compressed air so you can work flawlessly without any breaks. This helps productivity and effectiveness when big or quick tasks are involved.

Understand the Working Air Compressor for Plasma Cutter:

This section throws light on the working of the air compressor for plasma cutter:

• Air Intake: The air compressor draws the surrounding air through its inlet valve.
• Compression: Now, the air is driven into the chamber at high pressure by means of a piston or a rotary screw.
• Storage: The air is compressed and stored either in a tank or reservoir and the plasma cutter is supplied by it whenever the need of the job arises.
• Regulation: A pressure regulator is a device that sets the airflow and permits the adjustment of output pressure to that of the plasma cutter.
• Delivery: The compressed air goes through the hoses to the torch that is turned into a plasma arc for cutting by being heated.

Part 2: How to Choose a Suitable Air Compressor for Plasma Cutter?

The right choice for air compressor for plasma cutter plays an important part in the work of the plasma cutter. By considering these factors, you can make the right choice:

What size air compressor is needed for the plasma cutter?

The tank capacity represented by the compressor size in gallon. The amount of gas you have to provide depends on your plasma cutter’s need and the duration of the cutting job. The larger tank capacity means that the work can be done uninterrupted because there is no need for compressor refill.

For the light to the moderate cutting jobs, you will need 20 to 30 gallon tank. Nevertheless, the industrial cutting requires at least a 60-gallon tank or more for constant application of cutting sessions.

PSI (lb/in2)

PSI shows the compressor’s air pressure. Most plasma cutter types have a certain minimum PSI to function properly. Usually about 60 to 100 PSI. You have to buy a compressor capable of continuously giving you the needed PSI.

Check whether the maximum PSI of the compressor will meet or exceed the minimum PSI requirement by the plasma cutter. Also, shop for compressors with pressure settings that can be adjusted to manage cutting tasks and materials.

CFM (ft3/min)

CFM means the air volume delivered by the compressor in one minute. Plasma cutters may have different CFM requirements for size and duty rating. Insufficient CFM may lead to reduced power to cut and poor arc stability.
Establish the CFM needs of the plasma cutter by checking through the specifications or consulting the manufacturer’s guidelines. Select a compressor with a CFM rating that satisfies or exceeds the plasma cutting device’s requirements for smooth and effective operation.

Motor:

The air compressor’s motor plays a major role in its performance and durability. Seek out compressors with powerful engines of high quality to satisfy the power requirements of your plasma cutter.
Remember the power (HP) and motor efficiency when choosing an air compressor. These motors provide a larger air volume and higher pressure, which is good for cutting heavy-duty applications. Moreover, motors with thermal overload protection should be considered, as they shield from overheating and extend the compressor’s life.

Voltages:

Be mindful of the voltage requirements of your air compressor to match your power supply. Most air compressors run on the standard household voltages including, but not limited to, 120V or 240V.
Discover what the power capacity available in your workshop or workplace is, and purchase an air compressor rated for the power supply. The air compressor should never be used at an incorrect voltage, otherwise it might result in an electrical problem or equipment breakdown.

Noise:

Study carefully the air compressor’s sound level, especially in residential or noise-sensitive areas. Some compressors can make a lot of noise that can be disruptive and hence violate noise regulations.
Search for a noise reduction air compressor that comes with insulated enclosures and/or low-noise motors. In addition, pay attention to the place of the compressor and whether soundproofing materials will be necessary to reduce noise pollution.
Finally, consideration of all the needs such as tank capacity, PSI, CFM, motor quality, voltage compatibility and noise level is most important. Besides, you could get the best performance and efficiency in your cutting operations if you choose an air compressor that runs according to the requirements of your plasma cutter and your workplace.
