Intermediate frequency transformer is a type of transformer unique to superheterodyne receiving devices that has a fixed resonant circuit. However, the resonant circuit can be fine tuned within a certain range to achieve accurate resonant frequency even after being connected to the circuit. Fine tuning is achieved by adjusting the relative position of capacitors or magnetic cores. The primary and secondary circuits of intermediate frequency transformers used in electronic tubes are usually tuning circuits, while transistors are available in two types: double tuning and single tuning.

Three pulse heating methods: preheating, welding, tempering; The welding section can be customized with increasing, decreasing, and cycling pulse numbers.
Proportional valve output interface: equipped with a proportional valve output interface, the output is 0-10V analog output, and can be customized for 10 pressure periods and their corresponding pressure control.
Constant current control: Generally, the primary constant current mode is used, with a repetition accuracy of less than 3% of the maximum output. Secondary constant current can also be used, with a repetition accuracy of less than 1% of the maximum output.
1. Counting function: It has the functions of cumulative counting of solder joints, spot counting, and production counting, which is convenient for production management. It can set welding current monitoring and output corresponding alarms to ensure welding quality.
2. It has a monitoring and display function, which includes the welding time, welding current, capacitor voltage, electrode voltage, and phase angle of each welding point.
3. Up to 63 sets of welding specifications can be stored, and the specifications can be selected to start through external 10 or programming.
4. Using RS232 or RS485 communication, equipped with relevant software and hardware, remote monitoring, maintenance, and data collection can be achieved.
5. Complete fault diagnosis and corresponding codes to remind users for easy customer maintenance.
