HY series inverter DC resistance welding power source is a new type of resistance welding power source developed with IGBT inverter technology, microcomputer control technology and modern power electronics technology. The principle of the equipment is shown in Figure 1. Due to the adoption of AC-DC-AC-DC conversion technology, the time control achieves millisecond accuracy, control response and control accuracy are greatly improved; DC output (Fig. 2) makes the welding process significantly improved; The inverter technology also makes the equipment have a series of advantages such as small size, energy saving and high efficiency; The application of dual CPU control technology 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 has complete functions, flexibility and convenience, and wide adaptability. This kind of equipment is especially suitable for spot welding of copper, nickel and other metal materials, alloy materials, precision parts and high-quality products.

Features of HY series inverter resistance welding power supply:

1) DC output. The welding current is pulsating DC (and the waviness is small), without the shortcomings of AC zero crossing discontinuous heating of the workpiece. The heat is concentrated, which improves the welding thermal efficiency. It is especially suitable for the welding of non-ferrous materials and some difficult welding materials. The welding process is stable, and the welding quality is significantly improved. At the same time, the electrode life is extended.

2) It adopts dual CPU control and has secondary current monitoring function.

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 current disorder, monitoring value overrun, network voltage overrun, overheating, etc.

5) The inverter bridge automatically turns off when the current is abnormal, which enhances the system protection.

6) Three section heating setting, with the function of slow current rise and fall, wide time setting range, suitable for complex welding process needs.

7) 8 groups of welding parameters can be selected through panel or input port, which is convenient for use of various welding varieties.

8) 7-inch touch screen display, displaying and inputting various contents at the same time.

9) Strong external communication functions: welding end, fault, overrun signal, RS-485 data communication port (optional), convenient for automatic welding.

10) EEPROM is used for data storage, without battery life problem.

11) Fast response. Because of the high inverter frequency (4kHz). The power on time control cycle is 0.25ms, 80 times higher than the 20ms of the common AC welding machine, and the control accuracy is significantly improved. Compared with the capacitor energy storage welding machine, it does not need charging and discharging, and its controllability is obviously enhanced. It is especially suitable for the welding of precision parts and high-quality, high-precision and high-speed welding.
