任何设备在使用过程中都会有耗损，只要经过恰到好处的保养，便可以有效的延长设备的使用寿命，那么数控焊接时要提前知道什么事项呢？

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?

检查设备供电是否正常

Check whether the power supply of the equipment is normal

供电电源是否正常，关系到设备是否能够正常使用和内部元器件寿命。例如：当供电电源如果出现缺相等情况，往往容易导则设备内部滤波电容炸裂、IGBT发热严重甚炸裂等异常情况。检查项目：

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:

供电开关处电源进线接头是否连接可靠，有无氧化、变色、冒烟、发红等异常情况；测量电网电压是否在380V±15％以内；供电电源线外观有无破损、挤压变形等异常情况；若电源线加长，则需要检查中间连接接头是否牢固、绝缘处理是否可靠。

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.

检查设备输出连接是否正常

Check whether the output connection of the device is normal

输出端连接是否可靠，关系到焊接（切割）过程是否稳定、连接寿命等。例如：如果输出端快速接头连接松动，在大电流焊接（切割）时，很容易将接头打火烧损，导致整个接头报废，并且更换也比较麻烦。检查项目：

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:

输出端焊接（切割）电缆连接是否可靠，有无发黑、冒烟、烧焦等异常情况；输出端焊枪（割枪）各接头连接是否可靠，有无漏气、漏水等异常情况；输出端控制线接头连接是否可靠，控制电缆外观有无破损、挤压变形等异常情况。检查频次：连接方式为快速接头连接，应该每天作业前检查一次；连接方式为螺栓螺母连接，应该每周检查一次。

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.检查和紧固设备内部导电部件的连接螺钉

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

山东数控焊接设备厂家建议用螺栓螺母紧固的部位，会因为发热、振动等原因，慢慢发生松动。如果不及时紧固，将导致整个连接点烧损，整机无法工作。设备除尘后，应对设备内部主要导电部件的连接螺钉进行检查和紧固。如果已经有打火现象的接点，应该将连接点进行打磨后，涂上导电硅脂，重新进行连接。

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.

此外焊机在长期的使用过程中难免会因为外力的碰撞导致外壳变形或者是生锈，内部的零件也会有所消磨，因此在年度的保养以及检查时要及时更换零件或修补外壳。更多相关内容就来网站http://www.tayfsk.com咨询吧。

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.tayfsk.com Consult.
