Suncoo Plasma Cutter Review

Suncoo plasma cutter

This machine is designed uniquely and produces constant current output.

The current can also be adjusted depending on the nature of the material to give excellent performance.

It normal situations, this cutter machine has a transfer frequency of above 85% and designed with different dynamic characteristics.

The Suncoo plasma cutter is to cutting stainless steel, copper, carbon steel, iron, aluminum, and other metals.

It operates at 40 amps and has a smooth cutting surface which is easy to operate.

Furthermore, it operates by inverting the frequency into high frequency, then reduces the voltage to commute current, and finally generates a powerful direct welding current using the PWM technology.

Dual Voltage Plasma Cutter

SUNCOO Plasma Cutter Electric Inverter Welder Machine

The Suncoo plasma cutter is made with heavy-duty construction and has a dual voltage capability of 120V and 230V.

It produces a current that ranges from 20-32 amp and 20-40 amp.

When operating it ensures that you connect this machine to the right input voltage and avoid overloading.

You should always keep an eye on the maximum duty current which response in regard to the duty cycle selected.

Overloading will damage and burn up this plasma machine.

If the voltage exceeds the allowance arrangement limit, the components of this cutter will be damaged.

You should always take preventive measures to avoid this situation.

You can watch the video Suncoo plasma cutter to know more about the assembly, the usage, and the reviews.

Pressure Gauge of the Suncoo Plasma Cutter

Control panel

The Suncoo plasma cutter for sale has an LED display and a pressure gauge having easy-to-use controls.

All you have to do is to open the power switch on, and the current volume and pressure will be displayed accordingly.

Adjust the gas pressure to the desired amount and then open the valve of the pressed air.

Open the control knob torch, and the electromagnetic valve will start immediately.

Ultra Strong Cutting Ability

With a Suncoo plasma cutter, cutting metals with high thickness becomes quite easy.

It has ultra-strong power which can cut up to a thickness of 4/9” and can cut different kinds of metals.

The temperature should be within -10 to 40 degrees centigrade and the dampness level should not exceed 80 percent.

You should try as possible not to use this machine in dropping the environment or in the sunshine.

Also, you should take preventive measures such as not using this machine in a polluted environment.

This cutting machine has 20 inches torch cable with an input capacity of 4.8KVA and an output of 96V.

It also has a duty cycle of 60% with an efficiency of 85%. When it exceeds the duty cycle, the inter heat-variable component stops working suddenly.

In addition, when using this machine, do not break the circuit immediately as the running fan enables the machine to cool down quickly.

When the temperature drops to the allowable range, you can use it again.

Safety when using the Suncoo plasma cutter

When using the Suncoo plasma cutter, ensure that the working area is well ventilated. This cutter is usually lightweight and has a compact structure.

The electromagnetic fields produce a high current in which the common airflow will not be able to cool down its components.

To regulate temperature, they fitted this machine with an axial-flow fan which cools down the machine.

You should also note that there is nothing blocking or covering the exhaust shutter.

Never forget that overloading will result in the burning up of the components.

The cutting current should strictly be according to the maximum allowable current when conducting all kinds of duty cycles.

Again, the power voltage should be in line with the main technical datasheet.

When the arc supporting frequency gets low, you can get rid of the oxidized film using abrasive paper.


When you want to maintain a plasma cutter, you must turn it off first before opening the house. Use clean and dry compressed air to remove the dust.

If you are operating the machine in a polluted environment; ensure that you remove the dust every day.

To avoid damaging the small components of the inter-machine, use pressure under a reasonable arrangement.

When using SUNCOO plasma cutter regularly, you should make sure to tighten the connectors and connect the cable circuit accurately.

You should keep this machine out of steam or water.

If, by accident, there is water entering the machine, dry it immediately, and check the insulation if it is on point.
