任何設備在使用過程中都會有耗損，只要經過恰到好處的保養，便可以有效的延長設備的使用壽命，那么數控焊接時要提前知道什么事項呢？

Any equipment will be worn out in the process of use. As long as it is properly maintained, the service life of the equipment can be effectively extended. What should be known in advance during NC welding?

檢查設備供電是否正常

Check whether the power supply of the equipment is normal

供電電源是否正常，關系到設備是否能夠正常使用和內部元器件壽命。例如：當供電電源如果出現缺相等情況，往往容易導則設備內部濾波電容炸裂、IGBT發熱嚴重甚炸裂等異常情況。檢查項目：

Whether the power supply is normal is related to whether the equipment can be used normally and the service life of internal components. For example, if the power supply is short of power, it is often easy to guide the internal filter capacitor of the equipment to burst, the IGBT is seriously heated and even burst, and other abnormal conditions. Inspection items:

供電開關處電源進線接頭是否連接可靠，有無氧化、變色、冒煙、發紅等異常情況；測量電網電壓是否在380V±15％以內；供電電源線外觀有無破損、擠壓變形等異常情況；若電源線加長，則需要檢查中間連接接頭是否牢固、絕緣處理是否可靠。

Whether the power inlet connector at the power supply switch is connected reliably, and whether there are abnormal conditions such as oxidation, discoloration, smoking, redness, etc; Measure whether the grid voltage is within 380V ± 15%; Whether the appearance of the power supply line is damaged, extruded and deformed; If the power line is lengthened, it is necessary to check whether the intermediate connection joint is firm and whether the insulation treatment is reliable.

檢查設備輸出連接是否正常

Check whether the output connection of the device is normal

輸出端連接是否可靠，關系到焊接（切割）過程是否穩定、連接壽命等。例如：如果輸出端快速接頭連接松動，在大電流焊接（切割）時，很容易將接頭打火燒損，導致整個接頭報廢，并且更換也比較麻煩。檢查項目：

Whether the output connection is reliable is related to the stability of welding (cutting) process, connection life, etc. For example, if the quick connector at the output end is loose, it is easy to ignite and burn the connector during high current welding (cutting), resulting in the scrapping of the whole connector, and it is troublesome to replace it. Inspection items:

輸出端焊接（切割）電纜連接是否可靠，有無發黑、冒煙、燒焦等異常情況；輸出端焊槍（割槍）各接頭連接是否可靠，有無漏氣、漏水等異常情況；輸出端控制線接頭連接是否可靠，控制電纜外觀有無破損、擠壓變形等異常情況。檢查頻次：連接方式為快速接頭連接，應該每天作業前檢查一次；連接方式為螺栓螺母連接，應該每周檢查一次。

Whether the welding (cutting) cable connection at the output end is reliable, and whether there are abnormal conditions such as blackening, smoking, charring, etc; Whether the joints of the welding gun (cutting gun) at the output end are connected reliably, and whether there are abnormal conditions such as air leakage and water leakage; Whether the connection of the control line connector at the output end is reliable, and whether the appearance of the control cable is damaged, extruded and deformed. Inspection frequency: the connection mode is quick connector connection, which should be inspected once a day before operation; The connection method is bolt and nut connection, which should be checked once a week.

4.檢查和緊固設備內部導電部件的連接螺釘

4. Check and tighten the connecting screws of the conductive parts inside the equipment

山東數控焊接設備廠家建議用螺栓螺母緊固的部位，會因為發熱、振動等原因，慢慢發生松動。如果不及時緊固，將導致整個連接點燒損，整機無法工作。設備除塵后，應對設備內部主要導電部件的連接螺釘進行檢查和緊固。如果已經有打火現象的接點，應該將連接點進行打磨后，涂上導電硅脂，重新進行連接。

Shandong CNC welding equipment manufacturers suggest that the parts fastened with bolts and nuts will slowly loosen due to heating, vibration and other reasons. If it is not fastened in time, the whole connection point will be burned and the whole machine will not work. After dust removal, the connecting screws of the main conductive parts inside the equipment shall be checked and tightened. If the contact has sparking phenomenon, the connection point should be polished, coated with conductive silicone grease, and then reconnected.

此外焊機在長期的使用過程中難免會因為外力的碰撞導致外殼變形或者是生銹，內部的零件也會有所消磨，因此在年度的保養以及檢查時要及時更換零件或修補外殼。更多相關內容就來網站http://www.oimhc.com咨詢吧。

In addition, during the long-term use of the welding machine, it is inevitable that the shell will be deformed or rusted due to the collision of external forces, and the internal parts will also be worn away. Therefore, the parts should be replaced or the shell repaired in time during the annual maintenance and inspection. Come to the website for more relevant content http://www.oimhc.com Consult.
