A plasma is a gas that is heated to a very high temperature and is highly ionized. It transfers the arc power to the workpiece. The high heat causes the workpiece to melt and be blown off, forming a working state of plasma arc cutting.

After the compressed air enters the torch, two channels are distributed from the air chamber to form a plasma gas and an auxiliary gas. The plasma gas arc acts as a molten metal, while the auxiliary gas cools the various components of the torch and blows away the molten metal.
The cutting power supply consists of 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 resistance, a three-phase bridge rectifier, a high-frequency arcing coil and a protection component. The high-leakage resistance leads to a steep external power supply characteristic. The control circuit completes the entire cutting process through the push button switch on the torch:
Pre-ventilation - main circuit power supply - high frequency arcing - cutting process - interest arc - stop.
The power supply of the main circuit is controlled by the contactor; the short-circuit of the gas is controlled by the solenoid valve; the control circuit controls the high-frequency oscillator to ignite the arc, and stops the high frequency after the arc is established.
In addition, the control circuit also has the following internal locking function: the thermal switch action, stop working.
Operating procedure
Before use and when cutting
1. It should be checked and confirmed that the power supply, gas source and water source have no leakage, air leakage, water leakage, and grounding or zeroing is safe and reliable.
2. The trolley and workpiece should be placed in proper position, and the workpiece and the cutting circuit should be connected positively. The slag pit should be provided under the cutting working surface.
3. The nozzle aperture should be selected according to the material, type and thickness of the workpiece to adjust the cutting power, gas flow and the amount of shrinkage of the electrode.
4. The automatic cutting trolley should be operated by empty car and the cutting speed should be selected.
5. Operators must wear protective masks, welding gloves, hats, filter dust masks and soundproof earmuffs. Persons who do not wear protective glasses are strictly prohibited from directly observing the plasma arc, and bare skin is strictly prohibited from approaching the plasma arc.
6. When cutting, the operator should stand at the windward position. It is possible to draw air from the lower part of the workbench and to reduce the open area on the workbench.
7. When cutting, when the no-load voltage is too high, the grounding, zeroing and torch handle insulation of the electrical equipment should be checked. The workbench should be insulated from the ground or the no-load circuit breaker should be installed in the electrical control system.

cutting samples
8. The high-frequency generator should be equipped with a shielded shield. After high-frequency arc striking, the high-frequency circuit should be cut off immediately.
9. The use of tantalum and tungsten electrodes shall comply with the provisions of Article 12.7.8 of JGJ33-2001.
Second, cutting operations and coordination of personnel protection
1. The plasma Cutting Machine used on site shall be equipped with a shed that is protected from rain, moisture and sun, and shall be equipped with corresponding fire-fighting equipment.
2. When cutting at high altitude, the seat belt must be fastened. Fire protection measures should be taken around the cutting and cutting, and there should be special guardianship.
3. When it is necessary to cut the pressure vessel, sealed container, oil drum, pipeline, workpiece with flammable gas and solution, the pressure inside the vessel and pipeline should be eliminated, the combustible gas and solution should be eliminated, and then the toxic, harmful and flammable flushing should be carried out. Substance; for containers containing residual grease, first flush with steam and alkaline water, and open the lid. After confirming that the container is cleaned, fill it with clean water before cutting. Measures to prevent electric shock, poisoning and suffocation should be taken during welding in the container. Airtight holes shall be provided for cutting sealed containers. If necessary, equipment ventilation equipment shall be installed at the inlet and outlet ports; the lighting voltage inside the container shall not exceed 12V, and the welder and the workpiece shall be insulated; special monitoring shall be provided outside the container. Cutting in containers that have been painted with paint and plastic is strictly prohibited.
4. It is strictly forbidden to cut the pressure vessel and pipeline under pressure, the charged parts, the force-bearing parts of the load-bearing structure and the containers containing flammable and explosive materials.
5. Rainy days must not be welded in the open air. When working in wet areas, the operator should stand in the place where the insulation is placed and wear insulated shoes.
6. After the operation, the power should be turned off and the air source and water source should be turned off.
