JYR series inverter DC hot pressing welding power source is a new type of power source developed by IGBT inverter technology, microcomputer control technology and modern power electronic technology. Due to the adoption of AC-DC-AC-DC conversion technology, the time control reaches second-level accuracy, and the control response and control accuracy are greatly improved; the DC output significantly improves the welding process; the inverter technology also enables the equipment to have small, A series of advantages such as energy saving and high efficiency: the adoption of microcontroller (MCU) and electronic technology enables the equipment to have excellent functions of modern equipment, including digital control, monitoring, fault diagnosis and protection, data transmission, etc. The equipment is fully functional, flexible and convenient. Adapt to a wide range. This type of equipment is especially suitable for spot welding of non-ferrous materials such as copper and aluminum, spot welding of alloy materials, spot welding of precision parts and spot welding of high-quality products.
Features of JYR-02L Inverter Hot Pressure Welding Machine:
1. DC output. The welding current is pulsating DC (and the waviness is small), without the shortcomings of AC zero-crossing and discontinuous heating of the workpiece, the heat is concentrated, and the welding thermal efficiency is improved. It is especially suitable for the welding of non-ferrous metal materials and some difficult-to-weld materials. The quality has improved significantly. At the same time, the electrode life is extended.
2. It is controlled by a microcontroller (MCU) and has the function of temperature monitoring.
3. The inverter bridge adopts soft switching technology to reduce switching loss and electromagnetic interference.
4. It has fault diagnosis and alarm functions such as temperature abnormality, monitoring value overrun, network voltage overrun, overheating, etc.
5. The inverter bridge current is automatically turned off when the current is abnormal, which enhances the system protection.
6. Two-stage heating setting, with temperature rising and falling function, wide time setting (0-250ms), suitable for complex welding process needs.
7. 20 groups of parameters are stored to facilitate the use of various welding varieties.
8. 240 × 128 LCD display, displaying a variety of contents at the same time.
9. Strong external communication functions: welding end, fault, counting signal, RS-232 data communication port, which is convenient for automatic welding.
10. EEPROM is used for data storage, and there is no battery life problem.
11. Fast response. Due to the use of a higher inverter frequency (4kHz), the power-on time control period is 0.25ms, which is 80 times higher than the 20ms of ordinary AC welding machines, and the control accuracy is significantly improved. Compared with the capacitor energy storage welding machine, it does not need charging and discharging, and the controllability is obviously enhanced, which is especially suitable for the welding of precision parts and high-quality, high-precision, and high-speed welding.
12. The advanced section temperature control system is adopted, and the heating state of each section can be flexibly set. Parameters such as temperature and time can be controlled with high precision.
13. The temperature rises rapidly and stably, and the local instantaneous heating method can well suppress the thermal influence on the surrounding components.
14. Display the temperature of each stage.
15. The closed-loop online feedback control of thermocouple improves the accuracy of temperature control.
