焊接設備在經過一段時間的使用后，總會因為種種原因出現故障。此時，用戶必須參照焊接設備使用說明書對照檢查與維修，即根據故障現象查找判斷原因。下面就來講講維修要點。

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.

對于有故障的焊接設備，在不明真相的情況下，不要急于動手，應該先了解設備的性能，詢問操作人員產生故障的前后經過及故障現象。對于生疏、復雜的焊接設備，還應先熟悉設備的電路原理和結構特點，遵守相應的規定。

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.

拆卸前要充分熟悉每個部件的功能、位置、連接方式以及與周圍其他器件的關系。在沒有焊接設備線路圖和組裝圖的情況下，應該一邊拆卸，一邊畫草圖，一邊進行標記，并對拆卸的實物作好標識，注意。

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.

一般應先檢查焊接設備外部有無明顯受傷的痕跡、電焊機部件有否缺損，并了解其維修史、使用年限、觀察使用場所環境和焊接工藝等，然后再對電焊機進行檢查。

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.

拆前應排除周邊的故障因素，如接線、接地、配電容量以及使用的焊接工藝是否正確，只有在確定是電焊機內部故障后才能拆卸，否則，盲目拆卸可能將焊接設備越修越壞，如焊條電弧焊、埋弧焊、鎢極氣體保護電弧焊、等離子弧焊及熔化極氣體保護焊機等。

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.

檢查焊接設備的機械部件和零件、潤滑、氣路、水路、油路系統是否存在問題，只有在確定這些系統無故障后，再進行電氣方面的檢查。

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.

山東數控焊接設備廠家認為您在檢查電路故障時，應利用檢測儀器儀表尋找故障部位，確認無接觸不良故障后，再有針對性地查看線路與機械的運作關系，以免誤判，如點焊、縫焊、凸焊及對焊等設備。

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.

當確定故障部位后再進行檢修和更換，解決產生的故障，使焊接設備盡快投入使用，減少因設備故障而造成的經濟損失。更多相關內容就來我們網站http://m.hk809.com進行咨詢吧。
