Practice: 1. When cutting before use and check that the power supply, gas supply, no water leakage, leakage, leaking flame cutting, ground or zero secure. 2. The car, the workpiece should be placed in the proper position, and should make the workpiece and the cutting circuit switched positive cutting, cutting working surface shall be provided with slag pit. 3. It should be based on the workpiece material, type and thickness selected nozzle diameter, adjustment of the cutting power, within the gas flow and the electrode shrinkage. 4. Automatic cutting car should be running through empty, and the cutting speed is selected. 5. The operator must wear protective masks, welding gloves, hats, dust masks and filters soundproof earmuffs. Who do not wear goggles plasma arc prohibited direct observation, bare skin is prohibited near the plasma arc. 6. Cutting Laser cutting, the operator should stand upwind operation. Ventilation from the lower part of the table, and should reduce the operating table of open area. 7. Cutting, when no-load voltage is too high, you should check the electrical grounding, then zero and torch handle insulation should workbench and floor insulation, or electrical control system installation load disconnection breaker. 8. The high-frequency generator should be provided with a shield cover underwater cutting, high-frequency arc, it should immediately cut off high-frequency circuits. 9. Using thorium, tungsten electrode should comply with Article 12.7.8 stipulates JGJ33-2001. Development of special CNC cutting machine. CNC pipe cutting machine is suitable for a variety of pipe cutting cylinder orthogonal, skew, cross and other eccentric phase used the line hole, square hole, oval hole, and can be cut at the end of the tube line intersects with inertia. This type of equipment is widely used in the production of metal structures, electrical equipment, boilers, oil, chemicals and other industrial sectors. CNC bevel cutting machine is one of the more high-end products in the line, rotary bevel cutting function of this type of equipment to meet the welding process open different angles, different plate beveling requirements. With the development of China's shipbuilding industry, the shipyard is the first in the introduction and use of CNC plasma cutting machine. With the development of technology, domestic and foreign shipyards have been equipped with a rotary bevel cutting function of CNC plasma cutting machine, built to meet the requirements of high-tech, high value-added ships.
