After a period of use, welding equipment will always fail for various reasons. At this time, the user must refer to the operation manual of the welding equipment for inspection and maintenance, that is, find and judge the cause according to the fault phenomenon. Here are the key points of maintenance.
For faulty welding equipment, don't rush to start without knowing the truth. You should first understand the performance of the equipment and ask the operator about the process and phenomenon of the failure. For unfamiliar and complex welding equipment, you should also be familiar with the circuit principle and structural characteristics of the equipment and abide by the corresponding regulations.
Before disassembly, be fully familiar with the function, position, connection mode of each component and the relationship with other surrounding devices. In the absence of welding equipment circuit diagram and assembly drawing, it is necessary to draw a sketch while disassembling and mark the disassembled objects, and pay attention to safety.
Generally, it is necessary to check whether there are obvious signs of injury on the outside of the welding equipment, whether the parts of the electric welding machine are damaged, understand its maintenance history, service life, observe the environment of the place of use and the welding process, and then check the electric welding machine.
Before disassembly, eliminate the surrounding fault factors, such as whether the wiring, grounding, power distribution capacity and the welding process used are correct. Only after it is determined that it is the internal fault of the electric welding machine, can it be disassembled. Otherwise, blind disassembly may make the welding equipment worse and worse, such as electrode arc welding, submerged arc welding, tungsten gas shielded arc welding, plasma arc welding and consumable electrode gas shielded welding machine.
Check whether there are problems in the mechanical components and parts, lubrication, air circuit, water circuit and oil circuit systems of the welding equipment. Only after confirming that these systems are free of faults, can the electrical inspection be carried out.
Shandong CNC welding equipment manufacturer believes that when you check the circuit fault, you should use the detection instruments to find the fault position, and then check the operation relationship between the line and the machine after confirming that there is no poor contact fault, so as to avoid misjudgment, such as spot welding, seam welding, projection welding, butt welding and other equipment.
When the fault location is determined, it can be repaired and replaced to solve the fault, so that the welding equipment can be put into use as soon as possible and reduce the economic losses caused by the equipment fault.
