Welding joint problem handling: intermittent customs clearance

表现：

  焊接状态时，出关断续，并且送丝/出气断续

Performance:

In the welding state, the customs clearance is intermittent, and the wire feeding/discharging is intermittent.

原因分析：

扳机按钮信号或者安全地锁信号丢失

Cause analysis:

Trigger button signal or safety lock signal is lost.

解决方案

按照其运行逻辑，只有【激光器扳机信号】和【安全地锁信号】有效时，才会出光（激光器状态正常），同时首页未出现任何报警

在出光断续的时候，通过监测页查看上述的两个信号那个会消失，针对消失的信号，做下一步监测

如果两个信号都存在

solution

According to its operation logic, only when 【 Laser Trigger Signal 】 and 【 Safe Lock Signal 】 are valid will light up (the laser status is normal), and there is no alarm on the homepage.

When the light is intermittent, check through the monitoring page which of the above two signals will disappear, and do the next monitoring for the disappeared signal.

If both signals are present

①安全地锁信号消失

把安全地锁夹子直接夹在刻度管上，看是否正常，如果正常，可能是板材的原因，有些板材如锈迹或油污会导致其接触不良

②扳机按钮信号消失

尝试用力按住扳机按钮，如果信号闪烁，可能存在扳机按钮接触不良的情况，更换扳机按钮（新款老款不通用）

③无法检测到信号丢失

因检测页面的刷新频率远低于芯片采样间隔，当瞬间断路后又恢复正常，这种情况下检测页面看不到。

针对这种情况，短接信号接口一的5/6脚，使其安全地锁生效，然后正常焊接看是否会出现

①safely lock signal disappears.

Clamp the safety lock clip directly on the calibration tube to see if it is normal. If it is normal, it may be the plate, and some plates such as rust or oil stain will lead to poor contact.

② The trigger button signal disappears.

Try to press and hold the trigger button hard. If the signal flashes, there may be poor contact of the trigger button. Replace the trigger button (new and old models are not common).

③ No signal loss can be detected.

Because the refresh frequency of the detection page is much lower than the sampling interval of the chip, it returns to normal after the instantaneous disconnection, in which case the detection page cannot be seen.

In view of this situation, short-circuit the 5/6 pin of signal interface 1 to make it lock safely, and then weld it normally to see if it will appear.
