After a period of use, the special welding equipment will always fail for various reasons. Next, Shandong welding machine manufacturer will talk about the maintenance method of welding machine equipment failure!
1. Ask first and move later
For the special welding equipment with faults, do not rush to work when the truth is unknown. You should first understand the performance of the equipment and ask the operator about the process and phenomenon of the fault. For unfamiliar and complicated special welding equipment, it is also necessary to be familiar with the circuit principle and structural characteristics of the equipment and observe the corresponding regulations.
Before disassembly, be fully familiar with the function, location, connection mode of each component and its relationship with other surrounding components. In the absence of the wiring diagram and assembly drawing of the special welding machine, it is necessary to draw a sketch while disassembling, mark at the same time, and mark the disassembled objects for safety.
2. Outside before inside
Generally, first check whether there are obvious signs of injury on the outside of the special welding equipment, whether there are defects in the parts of the electric welding machine, and understand its maintenance history, service life, observe the environment of the use site and welding process, and then check the electric welding machine.
The surrounding fault factors, such as wiring, grounding, power distribution capacity and welding process used, shall be eliminated before removal. The removal can only be carried out after the internal fault of the welding machine is determined. Otherwise, the blind removal may make the special welding machine and equipment worse and worse, such as shielded metal arc welding, submerged arc welding, tungsten gas shielded arc welding, plasma arc welding and MIG welding.
3. Power before power
Check whether the mechanical components and parts, lubrication, air circuit, water circuit and oil circuit system of the special welding machine have problems. Only after confirming that these systems are free of faults, carry out electrical inspection.
When checking the circuit fault, use detection instruments and meters to find the fault location. After confirming that there is no bad contact fault, check the operation relationship between the line and the machine in a targeted way to avoid misjudgment, such as spot welding, seam welding, projection welding, butt welding and other equipment.
Therefore, the repair and replacement shall be carried out after the fault location is determined to solve the fault, so that the special welding machine can be put into use as soon as possible and reduce the economic losses caused by the equipment fault.
