直觀法是根據焊接專機等電器元件故障的外部表現，通過看、聞、聽等手段檢查判斷故障的方法。下面來講講該設備的維修檢查步驟內容吧。

Visual method is a method to check and judge the fault by means of seeing, smelling and listening according to the external performance of the fault of electrical components such as welding machine. Let's talk about the maintenance and inspection steps of the equipment.

1）調查情況

1) Investigation

向操作者和故障發生時的在場人員詢問情況，包括故障外部表現、大致部位以及發生故障時的環境情況。如有無異常操作、明火、熱源等是否靠近電器元器件、有無腐蝕性氣體侵入、有無漏水、是否有人修理過以及修理的內容等。

Ask the operator and the personnel on site when the fault occurs, including the external performance of the fault, the approximate position and the environmental conditions when the fault occurs. For example, whether there is abnormal operation, open fire, heat source, etc., whether it is close to electrical components, whether there is corrosive gas intrusion, whether there is water leakage, whether someone has repaired it, and the content of repair.

2）初步檢查

2) Preliminary inspection

根據調查的情況，查看有關電器元器件外部有無損壞、連線有無斷路、松動，絕緣有無燒焦，螺旋熔斷器的熔斷指示器是束跳出，電器元器件有無進水和油垢，開關位置是否正確等。

According to the investigation, check whether the external of relevant electrical components are damaged, whether the wiring is broken or loose, whether the insulation is burnt, whether the fusing indicator of the screw fuse jumps out, whether the electrical components have water and oil dirt, and whether the switch position is correct.

3）試焊

3) Test welding

通過初步檢查，確認沒有可能使故障進一步擴大和造成人身、設備事故后，可以通電。

After preliminary inspection, it is confirmed that there is no possibility to further expand the fault and cause personal and equipment accidents, it can be powered on.

穩定無異常情況后，可進一步做焊接試驗檢查，焊機在正常工作中要注意有無嚴重跳水、異常氣味和異常聲音等現象，一經發現應立即停止，切斷電源。

After it is stable and free of abnormal conditions, further welding test and inspection can be carried out. During normal operation of the welding machine, attention should be paid to whether there are serious diving, abnormal smell and abnormal sound. Once found, it should be stopped immediately and the power supply should be cut off.

山東焊接專機廠家提醒您，注意檢查電器元器件的溫升及電器元器件的動作程序是否符合焊接設備原理圖的要求，從而發現故障部位。

Shandong welding machine manufacturer reminds you to check whether the temperature rise of electrical components and the action procedure of electrical components meet the requirements of the schematic diagram of welding equipment, so as to find the fault location.

注意，設備使用后，應及時檢查附件，設備油污，保證庫內指定位置清潔放置。要定期對設備進行檢備，補充潤滑油，以上內容希望給您幫助，更多內容就來我們網站http://www.haohuoxian.com進行咨詢吧。

Note that after the equipment is used, the accessories should be checked in time to remove the oil stain on the equipment and ensure that the designated position in the warehouse is clean and placed. We should regularly check and prepare the equipment and replenish lubricating oil. I hope the above content can help you.
