According to "China Electric tools industry demand forecast and Transformation upgrade Analysis report" Statistics,
In the 60 's, with the development of battery manufacturing technology, there appeared a battery power tool without power cord with Ni-CD battery.
In 1895, the German overtone produced the world's first DC drill. The housing is made of cast iron and can drill 4mm holes in the steel plate.
① small size, light weight, saving manufacturing materials, portable, easy to move.
Inverter process requires high-power electronic switching devices, the use of insulated gate bipolar transistor IGBT as a switching device inverter
The inverter welding and cutting equipment consists of an inverter power supply and an external device. wherein the inverter is the core of
At present, 15~100khz welding and cutting technology has matured, product quality is high, has formed a series of products.
The research and development of inverter welding machine in China started in the late 1970s and began to develop in the 1980s.
"Inversion" and "rectification" are the two opposite concepts.
Rectification is the process of converting alternating current into direct current,
