Which compressor for plasma? - Plasma cutters

In today's article, we discuss which air compressor to choose for a plasma cutter. Plasma cutters are highly efficient metal cutting tools, whose performance largely depends on the quality and specifications of the compressor being used. Selecting the right compressor is key to ensuring optimal cutter operation, achieving the highest cutting quality, and extending the device's lifespan. What kind of compressor should you invest in for a plasma cutter? Let’s find out.

What is an air compressor?

An air compressor is a device that compresses air, increasing its pressure. In the case of plasma cutters, the compressor supplies compressed air necessary for generating plasma—a form of ionized gas capable of precisely cutting metals. Which compressor is best for a plasma cutter? It’s important to understand the subject well, as choosing the wrong compressor can result in inefficient machine operation, leading to poor cutting quality and increased wear on consumables.

Types of compressors for plasma cutters

At CORMAK, we offer screw and scroll compressors, which provide benefits to meet diverse user needs. Below is an overview of two types of compressors to help you decide which compressor to choose for plasma cutting and achieve the best results.

Screw Compressors

Screw compressors are commonly used in industrial applications due to their high efficiency and reliability. They operate with two rotating screw rotors that draw in and compress air. This type of compressor is characterized by several key features:

• Efficiency and continuous operation – Screw compressors can work continuously for extended periods, making them ideal for large production facilities.
• Low noise emission – Thanks to screw technology, these compressors are relatively quiet, improving workplace conditions.
• Energy efficiency – Modern screw compressors are equipped with Variable Speed Drive (VSD) systems, adjusting operating speed to current air demand, allowing for energy savings.

Scroll Compressors

Scroll compressors, while less common than screw models, are appreciated for their efficiency and compact size. They work using two spiral elements—one remains stationary while the other rotates to compress air. Here are their advantages to help you choose the right compressor for plasma cutting:

• Compact size and lightweight – Scroll compressors are smaller and lighter than screw compressors, making them ideal for mobile plasma cutters and small workshops with limited space.
• Low maintenance costs – With fewer moving parts and a simpler design, scroll compressors require less maintenance and are less prone to breakdowns.
• Quiet operation and high air purity – Like screw compressors, scroll models operate quietly. Additionally, the compressed air they produce is very clean.

Key compressor specifications for plasma cutting

When deciding which compressor to choose for a plasma cutter, several important parameters should be considered.

• Airflow (CFM)

CFM (cubic feet per minute) measures the airflow rate of a compressor. A higher CFM means more air is delivered, increasing efficiency.

• Operating pressure (PSI)

Plasma cutters require a specific operating pressure, usually between 90-120 PSI. It is important to ensure that the compressor can maintain a steady pressure within this range.

• Tank capacity

A larger tank capacity allows for more stable air delivery. For plasma cutters, it is recommended to have tanks with a capacity of at least 200 liters.

Maintenance tips for compressors

Choosing the right compressor for your plasma cutter is just the first step. Once you have the perfect unit, it’s essential to remember that regular maintenance and cleaning are necessary to ensure the compressor's longevity. Periodic oil and filter changes following the manufacturer's recommendations will ensure optimal device performance.
