Reasons for non welding of intermediate frequency spot welding machine
Release time:2022-03-15

When welding workpieces of products, there may be some problems that are not caused by the machine itself and affect the firmness of the welding points. Today, let's sit down and have a cup of tea to talk about the reasons why the intermediate frequency spot welding machine does not weld.

1. Materials that have been welded may encounter problems during repair welding.

2. One of the three live wires connected had poor contact, causing the power grid to pull severely and the workpiece to fail to weld.

3. The screws of the two wires between the transformer and the control box are loose;

4. The copper plate connecting the transformer and the copper strip screw connecting the upper cylinder are loose.

5. The electrode tip is too dirty and has oxide skin, which leads to good contact between the top and bottom, resulting in the inability to conduct current.

In order to ensure that the quality of the intermediate frequency spot welding machine is qualified every day, during work hours, the worker first checks whether the circuit and waterway are normal, whether the return water flow rate has a flow rate, and whether there are any water flow errors in the control system. Because the inverter spot welding machine is based on the principle of dual point overcurrent welding, if one of the welding heads has oxide skin, it will cause failure to weld. When welding normally, regularly repair the welding head with a file, depending on the material of the welded product. For example, galvanized sheet needs to be repaired every half an hour, while ordinary cold plate and stainless steel sheet need to be repaired every five to six hours. In order to ensure the cleanliness of the electrode surface, the parameters in the control box must be adjusted according to the material of the workpiece.
