Problems solved by technology

[0002] At present, in the field of high-frequency induction heating equipment application technology, especially brazing machines for composite pot bottoms, most of them use tube-type high-frequency induction heating or transistor small-scale medium and high-frequency induction heating, and use tube-type existing equipment. Huge volume, high energy consumption, power utilization rate is only about 45%, and there are disadvantages of high voltage risk, radiation damage, inconvenient operation, and high cost; and the use of small transistor heating has low power, low work efficiency, and heating Problems such as unevenness, poor stability, and many faults

Although Chinese patent ZL99207275.1 discloses a brazing machine with solid-state high-power medium and high-frequency induction heating equipment, they are all ordinary hardware circuits, automation, and intelligence are not high, and the processing and welding speed still needs about 1 minute.
