Problems and solutions for the use of high-frequency heating machines

Many people know about the high-frequency heating machine, but there are some small problems when using it. Our customers don't know how to call us for help when using them. Our technicians give them satisfactory answers. Here are a few small ones. Share the problem with you.

1. Q: What is the maximum heating temperature of the high-frequency heating machine?

Answer: There is no limit, the temperature depends on the material to be heated, heating power, heating time, heat dissipation conditions, etc. For example, when heating metals such as copper and iron, it is no problem to heat them until they melt. For example, in the melting of artificial diamonds, the temperature can reach 3000 degrees Celsius.

2. Q: What is the reason why the high-frequency heating machine cannot be started?

Answer: There are many reasons for the failure to start, it may be caused by internal scale blockage; it may also be that the circulating water temperature is low, the temperature sensor inside is broken, you can unplug it and try it out; whether the rectifier board is normal; whether the pre-magnetization resistor is blown And whether the low-pass filter is disconnected; the induction coil is short-circuited; the igbt problem; the transformer is burned, etc., these are the reasons for the machine failure. Generally, the failure of the power tube, the start tube and the filter capacitor is the main factor.

3. Q: How to choose the frequency of high-frequency heating machine welding, and what conditions are related?

A: Welding is a type of welding method that uses resistance heat generated by high-frequency current flowing through the connection surface of the workpiece, and realizes the interconnection between metals under the condition of applying (or not applying) upsetting force. The high frequency range is 300-450kHz, and the specific frequency is related to the properties of the material you want to weld, the cross-sectional area of the weld and the welding speed. The process has to be explored according to the specific situation.
