It has great effective output power, and its output current will change according to the load. A special induction plate is installed, which ensures lower leaking ratio of magnetism and better cooling condition, so that the machine is characterized by short sticking time, great fastness, high speed, easy operation and stable performance.Even if the mouth of the bottle is dampened, the machine still can accomplish its work perfectly. Besides, the machine is prevented from over current, under voltage, over voltage or lack of water. It will stop automatically when there is no bottle in the specified position. And it also has functions of continuous counting and automatic rejection to caps without aluminum foil.
