When the monitoring function of the number of welding points in the intermediate frequency spot welding machine is effective, the monitoring of each welding point is increased by 1. When the actual monitoring parameter "monitoring number of welding points">="large welding points", an alarm is triggered, and a fault message is output. The terminal alarm is also output, and the next welding is prohibited from starting. Only after clearing the alarm can it be started; It can be cleared through an external reset terminal or reset to zero under this monitoring parameter through a programmer. When both the welding point monitoring and production numbers are effective, and the number of monitored welding points reaches a large welding point, the production count is incremented by 1. When the actual monitoring parameter "production count">="large production count", an alarm is triggered, and a fault message is output. The terminal alarm is also triggered, and the next welding is prohibited from starting. Only after clearing the alarm can it be started; It can be cleared through an external reset terminal or reset to zero under this monitoring parameter through a programmer.

1. When using the controller, the chassis must be firmly grounded;

2. The control box can only be used after connecting the cooling water, and it is necessary to ensure that the cooling water has sufficient flow and pressure. Regularly (once a month) check the working condition of the water cooling system (whether the water flow is smooth, whether there is any leakage, etc.);

3. When powered on, it is not allowed to open the controller box, and it is also not allowed to touch various parts inside the box with hands to avoid electric shock (there is a high voltage of 600V inside the box);

4. Note that after the power is disconnected and the internal circuit board indicator light goes out, there is still a voltage of nearly 30V on the internal energy storage capacitor of the controller. Please pay special attention to the maintenance of the controller!
