Sparkless fast electric saw is driven by DC 12V-18V. It is divided into straight saw and circular saw. The characteristics of fast electric saw are: using electronic speed control switch, low vibration, no spark in metal sawing, it can quickly replace different saw blades to cut various materials, such as steel, iron, aluminium, wood, plastic and so on. Saw blades are made of special materials. They are hard and tough. They can be cut continuously by arc. However, more attention has been paid to the length of power supply that can provide them to work. The matching 18V rechargeable battery, weighing about 1 kg, can make the fast saw work for about 20 minutes continuously. But with a large battery, it can work for about 90 minutes. If the battery clamp is connected, the power supply on the car can be connected. As long as the generator of the car is started, the fast electric saw can be used indefinitely.
