Choosing Reliable Plasma Cutter Machine Supplier in China

Plasma cutter machine comes from plasma welding. includes Plasma cutting mode and oxygen cutting mode.

Why has it become so popular?

The reason is that plasma cutting produces no metal chips and is very precise during the cutting process.

Due to the repetitive cutting pattern, plasma cutting machines are very bulky, mainly designed for mass production and are widely used in most metals work

such as cars, motorcycles, chemical machinery, nuclear industry, engineering machinery, aluminum structures, ships, etc.

This article will explain the factors of plasma cutting machines and how to choose the right Plasma Cutter Machine Supplier.

What is a plasma cutting system?

A plasma cutting machine is a machine that processes metal materials with the help of plasma cutting technology.

The mechanized cutting process mainly involves cutting with CNC knives or industrial robots.

The heat source for the molten metal is a plasma arc that glows between the electrode and the workpiece.

This means that plasma cutting is only used for conductive materials, mainly mild steel, stainless steel and aluminum.

Three essential factors about plasma cutting machine

1. Air supply unitar machine life and consumable life.

In the plasma cutter section, you need about 7 to 8 CFM (cubic feet per minute) at 90 psi. This is a requirement that most compressors can handle.

However, when choosing a compressor to supply air, you need to consider a number of factors. 3 to 5 HP 60 gallon compressors can typically output 11 CFM.

This will meet the needs of most plasma cutters, but you will need to consider whether you want to use any other air at the same time.

With a compressor of this size only about3 CFM above the minimum, and with only a 60 gallon tank, your compressor will likely run non-stop.

Most cheap 60 gallon compressors are not designed for this.

2. Power supply

The cutting quality of the CNC Plasma Cutter work cutting machine is strong correlated with the quality of the power supply.

A good power supply will guarantee good cutting quality. Most plasma cutter power supplies are rated based on cutting capability and current.

If you typically cut thinner metals, you should consider a low-current plasma cutting power source.

When choosing a low-current plasma power source to cut thicker metals, the cut quality may not be maintained.

A variety of reasons causes this situation. It may be that the cutting speed is too fast, or the metal thickness exceeds the optimal cutting thickness of the power supply.

Every plasma cutting power source(plasma generator) has an optimal cutting thickness, so make sure it meets your demands.

In general, the optimal cutting thickness of the power supply must be 60%-70% of the limited cutting thickness

If you want to cut for a long time or cut automatically. Make sure to check the machine’s workload continuity rate.

The load duration is calculated as the continuous working time before the cutter overheats and needs to cool down.

Workload duration is usually determined as a percentage based on a 10-minute criterion. For example, a 60% duty cycle and 100 amps of current means you can cut for 6 minutes at 100 amps of current output (10 minutes is 100%). The longer the workload lasts, the longer you can keep cutting.

3. Cutting Equipment

Thermal plasmas are produced in plasma torches by direct current (DC), alternating current (AC), radio frequency (RF) and other electrical discharges.

DC torches are the most commonly used and the most studied because compared to AC: “Low noise, stable and easy-to-control operation, reduced electrode consumption and refractory wear, and lower power consumption.

All in all, DC torches have significantly lower operating costs than other types.

The exact form of the cutting torch depends on the current rating of the torch.

Generally, the cutting torch below 130A adopts an air-cooled structure,

and the cutting torch above 130A adopts a water-cooled structure.

The electrodes in the torch can be pure tungsten, thoriated tungsten, bell-shaped tungsten rods or inlaid electrodes.

Cast tungsten is preferred as the electrode material. It has the advantages of simple cutting and cutting of various non-metallic materials.

After purchasing a plasma cutter for the first time, the most important ongoing cost will be the cutting tip and electrode.

So before you pick up your plasma cutter, learn as much as you can about how fast your machine can use these items.

A tip damaged due to poor technique or electrode wear can slow down the cut or reduce the quality of the cut,

so it is generally recommended to replace both the tip and electrode for optimal cutting performance.

The following equation is recommended to determine the ongoing cost of plasma cutting equipment:

“The cost of consumables, or the total cost of consumables divided by the life of the consumables (in arc time per hour), is the most useful measure.

For example, if the nozzle costs $5, the electrode costs $7, and a set lasts 3.5 arc hour, then the hourly cost or CPH is ($5 + $7)/3.5 = $3.43.”

Why choose China manufacturer as plasma Cutter Machine Supplier?

1. Affordable price of quality plasma cutter machine

Chinese-made plasma cutting machines are several times cheaper than other European or American plasma cutting machines, and consumables such as cutting nozzles and electrodes are also much cheaper.

In terms of quality, China’s plasma cutting machines have no significant disadvantage.

China’s manufacturing industry has now adopted domestic plasma cutting machines on a large scale and has also achieved a lot of remarkable achievements. During the COVID-19 epidemic, domestic plasma cutting machines provided strong support for China’s domestic production industry and maintained stable product exports.
