Can a plasma cutter cut through a safe?
Recently, I saw a very interesting topic, the safe at home cannot be opened, what should I do? At this time, some netizens suggested that the plasma-cutting machine can open the safe. Is this true?
Not to mention, someone has really tested whether the plasma-cutting machine can cut through the safe, let’s take a look!
Unexpectedly, cutting a hard safe with a plasma cutting machine is as easy as cutting tofu. In fact, this is mainly because of the working principle of the plasma-cutting machine
How does a portable plasma cutting machine cutter work
The working principle of plasma cutting machine
The principle of a plasma cutting machine is to use the high energy density and instantaneous high temperature of plasma to melt metal materials, so as to realize cutting, welding, and other processes. During the cutting process, the plasma gun generates an arc discharge through the power supply, which ionizes the gas atoms to form a plasma.
How does plasma work?
Plasma is a gas state in a high-energy state, with characteristics such as ionization, conductivity, and radiation. The high energy density and instantaneous high temperature of plasma can instantly melt metal materials and form high-speed airflow, thereby achieving the purpose of cutting metal materials
Plasma is a gas heated to an extremely high temperature and highly ionized, which transfers the arc power to the workpiece, and the high heat causes the workpiece to melt and be blown off, forming the working state of plasma arc cutting.
After the compressed air enters the cutting torch, it is divided into two paths by the air chamber to form plasma gas and auxiliary gas. The plasma gas arc melts the metal, while the assist gas cools the torch components and blows away the molten metal.
The cutting power supply includes two parts, the main circuit, and the control circuit. The electrical principle: the main circuit includes a contactor, a three-phase power transformer with high leakage reactance, a three-phase bridge rectifier, a high-frequency arc coil, and protection components. The external characteristics of the power supply are caused by high leakage reactance. The control circuit completes the entire cutting process through the button switch on the torch:
Pre-ventilation—main circuit power supply—high-frequency arc ignition—cutting process—arc rest—stop.

How to use a portable plasma cutting machine
- Preparations
Before using the plasma cutting machine, preparation work is required. First, check whether the power supply of the cutting machine is normal, then check whether the air source is sufficient, and finally, check whether the cutting head of the cutting machine is installed correctly. - Adjust cutting parameters
Before cutting, it is necessary to adjust the cutting parameters according to the material to be cut.
Generally speaking, cutting parameters include cutting current, cutting speed, gas flow, etc. Different materials require different cutting parameters, which need to be adjusted according to the actual situation. - Start cutting
Before cutting, the cutting head needs to be aligned with the position to be cut. Then press the start button of the cutting machine to start cutting. During the cutting process, it is necessary to keep the proper distance between the cutting head and the material so as not to affect the cutting effect.
Tips for using a portable plasma cutting machine
- Choose the right gas
When cutting with a plasma cutter, gas is required to protect the cutting head and cutting area. Different gases have different effects on the cutting effect, so it needs to be selected according to the actual situation. Generally speaking, oxygen can increase cutting speed, nitrogen can improve cutting quality, and argon can improve cutting accuracy. - Keep the cutting head clean
When cutting with a plasma cutter, the cutting head is in constant contact with the material and is susceptible to contamination. Therefore, the cutting head needs to be cleaned regularly to maintain its cutting effect. - Control cutting speed
When cutting, the control of cutting speed is very important. If the cutting speed is too fast, the cutting quality will be reduced; if the cutting speed is too slow, time and gas will be wasted. Therefore, it needs to be controlled according to the actual situation in order to achieve the best cutting effect.
Precautions for using portable CNC cutting machine
When using a portable CNC cutting machine, first pay attention to the fact that there are no foreign objects obstructing or scratching within the operating range. Portable CNC cutting machines have very little power and are all stepper motors. When encountering obstacles during use, you will encounter phenomena such as stopping or losing steps, which will affect the cutting accuracy of the CNC cutting machine.
Beware of derailment. In the X-axis and Y-axis directions, the portable CNC cutting machine does not have soft and hard limits like the gantry cutting machine, so pay attention to the size of the operating range during operation to avoid derailment during the cutting process, resulting in Cutting accuracy is missing or work efficiency is reduced.
The cleaning of the track and the sufficient lubrication of the equipment. The factors such as the power source of the equipment mentioned above hinder the operation. It also involves factors such as foreign objects on the track or unsmooth lubrication. Rack lubrication. It mainly involves the Y-axis and Z-axis. The Y-axis is because there will be very small foreign objects falling on it and it is difficult to find them. The Z-axis is because the closest to the cutting torch is polluted and the micro-drive motor is smaller. So pay attention to the lubrication of the Y-axis and Z-axis during use.
