Product Description

QIZHI QZ99 Capacitive Energy Storage Stud Welding Machine

1. Key Features
1. Advanced design, powerful functionality, small size, light weight, and easy to operate.
2. Suitable for welding various metal materials such as low-carbon steel, stainless steel, copper alloy, aluminum alloy, etc.
3. Due to the high power of the charging transformer and fast charging recovery, up to 40 energy storage studs can be welded per minute.
4. The welding machine has the function of preventing electric shock. When the workpiece is not in contact with the base material, press the welding gun switch, and the switch light will be on, without any discharge; When the workpiece has good contact with the base material, the indicator light will be on. Then, press the switch and both indicator lights will be on simultaneously. Then welding can be carried out.
5. Using thyristor contactless modules to replace the charging of contactless DC relays, contactless charging technology is incomparable to traditional relay charging. The lifespan of relay contacts is only tens of thousands of times, while contactless thyristor modules can reach over a million times.
6. Capacitors are the main components of welding machines and also the main device that determines the welding quality. We choose long-life capacitors produced by listed companies, with a service life of up to 2000 hours. Calculated based on a welding cycle of 3ms, the service life can reach hundreds of millions of times.
7. The welding machine is equipped with a built-in fan and overheating safety control system. If the temperature rises due to overload or poor ventilation, the welding machine will automatically alarm.
8. Welding machines usually use single-phase 220V AC power supply, and 110V or other power supply can also be customized according to customer needs.
9. According to the size and material of the welding studs, this series of welding machines has multiple models of QZ99, QZ132, and QZ188B for customers to choose from.

3. Application
Experiments have shown that if base metals are carbon steel, stainless steel, aluminum and other metal materials when the thickness of the base metal does not exceed 2.5mm, QZ99 should be selected for energy storage stud welding that below M3, M4, M5, M6 to meet the welding effect. Especially when M6 * 15 aluminum energy storage stud are welded on aluminum plates below 2mm, which is particularly excellent. If the base material is less than 1.0mm, the M8 energy storage stud can be welded normally.

4. Suggestion
The most reasonable choice is to use QZ99 energy storage welding when the thickness of the base material is less than 2.5mm and the size of the energy storage welding stud is less than M6.
