焊接專機出現(xiàn)問題后有哪些方法檢查？在這里講一下對比、置換元器件、逐步開路（或接入）法，展開內容分析一番吧。

What are the methods to check when there is a problem with the welding machine? Here we will talk about the methods of comparison, replacement of components and parts, and gradual open circuit (or access), and carry out the content analysis.

1）對比法

1) Contrast method

把檢測數據與圖樣資料及平時記錄的正常參數相比較來判斷故障。對于無資料又無平時記錄的焊接設備，可查閱相關手冊或者產品說明書，也可以與同型號的完好焊接設備相比較。

Compare the test data with the drawing data and the normal parameters recorded at ordinary times to judge the fault. For welding equipment without data or usual records, you can refer to the relevant manuals or product manuals, or compare it with the intact welding equipment of the same model.

電路中的焊接設備元件屬于同樣用途性質或多個元件共同控制同一設備時，可以利用其他相似的或同一電源的元件動作和數據情況來判斷故障。

When the welding equipment components in the circuit belong to the same purpose or multiple components jointly control the same equipment, the action and data of other similar components or components of the same power supply can be used to judge the fault.

2）置轉換元件法

2) Set conversion element method

為了保證焊接設備的利用率，某些電路的故障原因不易確定或檢查時間過長時，利用相同焊接設備上可轉換的同一性能良好的元器件實驗，以證實故障是否由此電器在元器件引起。

In order to ensure the utilization rate of welding equipment, when the fault cause of some circuits is difficult to determine or the inspection time is too long, use the same components with good performance that can be converted on the same welding equipment to test to confirm whether the fault is caused by the electrical appliance in the components.

運用轉換元件法檢查時應注意，當把原焊接設備拆下后，要認真檢查是否已經損壞，只有肯定是由于該焊接設備本身因素造成損壞時，才能換上新焊接設備，這樣可以防止新?lián)Q元件再次損壞。

When using the conversion element method to check, it should be noted that when the original welding equipment is removed, it should be carefully checked whether it has been damaged. Only when it is certain that the damage is caused by the welding equipment itself, can the new welding equipment be replaced, so as to prevent the new components from being damaged again.

3）逐步開路（或接入）法

3) Step by step open circuit (or access) method

山東焊接專機設備中多支路并聯(lián)且控制較復雜的電路短路或接地時，一般有明顯的外部表現(xiàn)，如冒煙、有燒焦痕跡等。電焊機內部或帶有護罩的電路短路、接地時，除熔斷器熔斷外，不易發(fā)現(xiàn)其他外部現(xiàn)象，這種情況可采用逐步開路（或接入）法檢查。

In Shandong special welding machine equipment, when multiple branches are connected in parallel and the circuit with complex control is short circuited or grounded, there are generally obvious external manifestations, such as smoking, burning traces, etc. When the circuit inside the welding machine or with shield is short circuited and grounded, it is not easy to find other external phenomena except the fuse is blown. This situation can be checked by the step-by-step open circuit (or access) method.

①逐步開路法

① Step by step open circuit method

遇到難以檢查的短路或接地故障，可重新更換熔斷器熔體，把多支路電路，一路路逐步或地從電路中斷開，然后通電試驗，若熔斷器一再熔斷，故障就在剛剛斷開的這條電路上。

In case of short circuit or grounding fault that is difficult to check, the fuse melt can be replaced again, the multi branch circuit can be disconnected from the circuit step by step or emphatically, and then the power on test. If the fuse blows repeatedly, the fault is on the circuit just disconnected.

然后再將這條支路分成幾段，逐段地接入電路。當接入某段電路時熔斷器又熔斷，故障就在這段電路及某焊接設備元件上。這種方法簡單，但容易把損壞不嚴重的焊接設備元件徹底燒毀。

Then the branch is divided into several sections and connected to the circuit section by section. When a certain circuit is connected, the fuse blows again, and the fault lies in this circuit and some welding equipment components. This method is simple, but it is easy to completely burn the components of welding equipment that are not seriously damaged.

②逐步接入法

② Step by step access method

電路出現(xiàn)短路或接地故障時，換上新熔斷器逐步或地將各支路一步一步地接入電源，重新試驗。當接到某段時熔斷器又熔斷，故障就在剛剛接入的這條電路及其所包該文章講述了焊接設備故障的檢查方法與維修經驗.含的焊接設備上。

In case of short circuit or ground fault in the circuit, replace the new fuse, gradually or emphatically connect each branch to the power supply step by step, and retest. When receiving a certain section, the fuse blows again, and the fault lies in the circuit just connected and its package. This article describes the inspection methods and maintenance experience of welding equipment faults, including welding equipment.

在排除焊接設備故障時，可用一根絕緣棒將有關繼焊接設備、接觸器以及電磁鐵等用外力強行按下，使其常開觸點閉合，然后觀察焊接設備部分或機械部分出現(xiàn)的各種現(xiàn)象，如電動機從不轉到轉動，設備相應的部分從不動到正常運行等。更多相關內容就來我們網站http://www.opedost.com咨詢吧。

When troubleshooting the welding equipment, an insulating rod can be used to forcibly press the relevant relay welding equipment, contactors and electromagnets with external force to close their normally open contacts, and then observe various phenomena in the welding equipment or mechanical part, such as the motor never turns to rotate, and the corresponding part of the equipment never moves to normal operation, etc. Come to our website for more relevant content http://www.opedost.com Consult.
