At present, the widely used welding equipment includes: electrode arc welding, submerged arc welding, tungsten gas shielded arc welding, plasma arc welding and butt welding. The same is that problems will occur after a long time of use. What should we pay attention to if we want to repair?
When the equipment is not powered on, judge the quality of the buttons, contactors, thermal breaker components and fuses of the welding equipment, so as to determine the fault. Power on test, listen to its sound, measure parameters, judge faults, and then carry out maintenance.
If the article describes the inspection methods and maintenance experience of welding equipment faults When the input phase of the electric welding machine is missing, and the measured three-phase voltage value cannot be judged, you should listen to its sound, and measure the voltage of each relative location separately, so as to judge which phase is missing.
For heavily dyed welding equipment, first clean its buttons, wiring points and contact points, and check whether the external control keys fail. Many faults are caused by dirt and conductive dust. Once cleaned, the faults are often eliminated. Especially in the construction site and other places with poor environment.
Some faults often account for a high proportion of the whole welding equipment faults, so it is often possible to get twice the result with half the effort to overhaul the power input part first. Then check other auxiliary parts of the welding equipment, such as walking, wire feeding and so on, according to the method of "outside first, then inside, machine first, then electricity, static first, then moving".
Failures caused by the quality of components and electrical components, assembly accessories or other equipment failures generally account for about 50% of common failures. The special faults of welding equipment are mostly soft faults, which need to be measured and maintained by experience and instruments.
Shandong automatic welding equipment manufacturers believe that the on-site fault cannot be judged at the moment, and they can also consult the technical personnel of the product production unit according to the contact information of the product manual. For example, some internal procedures of spot welding, seam welding, projection welding, butt welding and other equipment should not be easily adjusted or changed without knowing or understanding, otherwise it will cause greater trouble.
We should be eager to replace the damaged electrical components and electrical components, and consider replacing the damaged electrical components or checking the printed circuit board after confirming that the peripheral equipment circuit is normal.
For the welding equipment with both debugging and fault, it is necessary to eliminate the fault before debugging. The commissioning must be carried out on the premise that the electrical circuit is completely free of fault and the wiring is correct (including the grounding wire).
