Product Description

QIZHI QZ 1600i IGBT Draw Arc Stud Welding Machine

1. Key Features

This machine applies advanced IGBT inverter technology, adopts microprocessor control technology and comprehensive functional design, and has the following technical advantages.

1. IGBT inverter technology has the following advantages:
(1) it significantly reduces the weight and volume of welding machines, which is 1/4 of the weight of similar welding machines in traditional engineering, convenient transportation.
(2) it significantly reducing copper and iron losses, improving overall efficiency, and achieving significant energy-saving effects.
(3) the switching frequency can reach up to 20KHZ, greatly improving the output dynamic characteristics.

2. Leading microprocessor control technology
(1) Easy arc ignition, low splashing, stable current, and beautiful weld formation.
(2) Improved the performance of the welding machine and met the welding process requirements for various types of studs.
(3) Wide range of current regulation (e.g. 2500 low current 100A, high current up to 2500A). The welding time range is large (e.g. 2500, with a minimum time of 10ms and a maximum time of 3000ms), and the excellent range of adjustment has achieved the full cycle screw welding function.
(4) The preset advance ventilation time and delayed gas closing time functions have significant energy-saving effects on the ventilation protection welding process. (5) It has protection functions such as over temperature, over current, over voltage, and under voltage. 6) It has the function of preventing secondary repeated welding. If the welding stud is not arced and the welding gun switch is pressed again, there is no output. After leaving the base material, it is re contacted and in good contact. Only by pressing the welding gun switch can it work and avoid overheating and burning through. Prevent accidents from happening.

3. Perfect functional design
(1) Dual fan dual channel heat dissipation design plays a decisive role in protecting electronic power devices. It can prevent component damage caused by excessive temperature.
(2) The carefully designed reactor and electronic arc ignition circuit can greatly improve the arc ignition performance and electrical stability of the welding gun and achieve perfect welding requirements.
(3)The design of electronic thrust circuits significantly improves the welding performance of extended cables, achieving long-distance welding.
(4) This machine is designed with a welding gun short circuit prevention function. Once the welding gun control cable is short circuited, the internal DC air switch of the welding machine will automatically disconnect, ensuring that the components are not damaged.
(5) This series of welding machines have strong adaptability to voltage difference and voltage instability in the power grid, and can work stably at low voltage of 320V and high voltage of 440V.
(6) Equipped with series welding guns, it can be used for welding pins, studs, and screw bars, and can achieve welding methods such as ventilated porcelain rings and unprotected joints. It is particularly important to meet the welding requirements, especially for welding large straight studs.
