The faults of equipment circuit or welding equipment can be roughly divided into seven categories: short circuit, overload, open circuit, grounding, wrong wiring, electromagnetic and mechanical part faults of welding equipment, aging of components and parts. Many of these faults are open circuit faults, including wire open circuit, virtual connection, looseness, poor contact of contacts, false soldering, false soldering and fuse fusing.
In addition to the resistance method and voltage method, there is a simpler and more reliable method to check such faults of Shandong automatic welding equipment, that is, the short-circuit method. That is, use a well insulated wire to short-circuit the suspected open circuit part. If it is short circuited to a certain place, the circuit will return to normal, indicating that there is an open circuit. The specific operation can be divided into local short connection method and long short connection method.
The components and parts that are continuously burnt out shall be replaced after the cause is found out; The voltage drop of the conductor shall be considered during voltage measurement; Do not violate the principle of equipment performance and the role of welding equipment. Before the first trial energization of the repaired welding equipment,
Gas shielded welding, spot welding, seam welding, projection welding, butt welding and other equipment should be ventilated and watered first. The parts that should be oiled also need to be oiled, and the surrounding obstacles should be removed. When working with power on, hands should not leave the power switch stop button. During the insurance period, the same amount of current or slightly less than the rated value should be used; Attention should also be paid to the selection of gear of measuring instruments.
The above inspection methods should be used flexibly according to the situation, but the safety operation rules must be observed to prevent personal and equipment injury accidents in the process of equipment maintenance, and two people should operate and monitor as much as possible.
The inspection, maintenance and troubleshooting of welding equipment shall be recorded according to relevant requirements. It is convenient to accumulate experience in inspection, daily maintenance and troubleshooting after similar faults occur in the future.
