What should I do if the solder joints of the capacitor energy storage spot welding machine are uneven?

capacitor energy storage type spot welding machine welding spot uneven reason is what? I believe that many friends are interested in, the following science and technology Xiaobian to explain to you.

capacitor energy storage type spot welding machine welding spot is uneven because the welding electrode is partially worn or the welding abrasive is uneven, please level it or correct the electrode to solve this problem. The debugging of spot welding machine mainly considers these three factors, namely welding current, welding time and welding air pressure. Changing any one will affect the welding. In turn, adjusting any one will change the welding effect. Try to slowly adjust the parameters suitable for your product. The machine can be adjusted by fluctuating up and down. Principle of

Capacitor Energy Storage Spot Welder: The energy storage welder should be connected in parallel with two groups of thyristors. When the trigger signal is given to group A, group A thyristors are turned on, and current output will occur. When stepping on the foot again, the SCR of group B is turned on, and the output current of group B is turned on. The next step is to turn on group a, so the rate cycle continues. How to repair the

capacitor energy storage spot welder?

1, check whether the trigger circuit signal is given to the thyristor.

2. PLC shows signals. Normally, two groups of trigger signals are normal.

3. The reason why there is no current output may be that there may be a primary switch (controlling the alternating conduction of two groups of thyristors) after the trigger signal. Is it normal.

4. Check whether the SCR is damaged (change the trigger signal line).

If the solder joint is still yellow and the contact surface ignites, you can increase the air pressure and try again.
