How does the current of the medium frequency spot welding machine increase?

In order to compensate for the reduction in welding current caused by electrode grinding, the controller of the medium frequency spot welder provides a current increasing function. Users can set up to 9 incremental segments according to actual conditions. The following parameters are involved in the current increment function: current increment, grinding point interval, current increment in the incremental section, number of welding points in the incremental section, and incremental notification point.

1. Current increment: The total current increment relative to the current set value during the current increment process. The value range is 0-999.9%.

2. Grinding point interval: the total number of welding points during the current increasing process. The value range is 1-9999.

3. Current increment in the step increase section: the percentage of the current in each step increase section relative to the total current increment (current increment). For example, the current increment of step section 1 is 1%, and the end current value of step section 1 is (1+current increment*1.%I)*welding current setting value.

4. Number of solder joints in incremental section: The number of solder joints contained in each incremental section accounts for the percentage of the total number of solder joints in the incremental process. For example, 1% is the percentage of the number of solder joints in incremental section 1 to the total number of solder joints. Therefore, the number of welding points in step 1 = grinding point interval * 1.%.

5. Step-up notification point: The first N-th point when the step-up process is nearing the end notifies the user that the step-up process is about to end.

6. Electrode warning point: When the number of grinding is close to a relatively large number of grinding points, that is, when the grinding process is about to end, a pre-warning is issued at the Nth point before the end, that is, the electric pre-current warning point, and its value range is 0-9999. When the value of the electrode warning point is 0, no electrode warning signal is output.

7. Number of grinding times: Users can set the grinding frequency of the electrode according to the actual situation.
