No display on LCD after startup:

在沒停電的狀況沒有顯現(xiàn)，可能是電源線有問題，查看電源線路反是不是有短路了，假如是保險(xiǎn)管燒毀，只需改換異常規(guī)格的保險(xiǎn)管就行了。

In the case of no power failure, there may be a problem with the power line. Check whether there is a short circuit in the power line. If the fuse is burned, just change the fuse with abnormal specification.

開機(jī)有LCD顯現(xiàn)，但是焊接無反響：

LCD displays when starting up, but there is no response during welding:

查看中頻點(diǎn)焊機(jī)的充電保險(xiǎn)管能否燒毀了，肯定后改換異常規(guī)格的保險(xiǎn)管應(yīng)該就能夠處置。

Check whether the charging fuse tube of the medium frequency spot welding machine is burned. After confirmation, replace the fuse tube with abnormal specification, which should be able to be disposed of.

有電源指示，無焊接火花：

With power indication and no welding spark:

很多緣由都會(huì)招致這種狀況的發(fā)作，比方說：焊接參數(shù)調(diào)理不正確、電極磨損過渡、電極下端面與電池距離過、;焊接開關(guān)損壞、光電開關(guān)損壞等等。

Many reasons will lead to the occurrence of this situation, such as incorrect adjustment of welding parameters, electrode wear transition, excessive distance between the lower end face of the electrode and the battery; The welding switch is damaged, the photoelectric switch is damaged, etc.

焊點(diǎn)不牢的現(xiàn)象：

Loose solder joints:

檢查電極頭外形、截面能否適宜。?普通焊板的時(shí)分會(huì)呈現(xiàn)中頻點(diǎn)焊機(jī)越來越難用的狀況，就是思索可能是電極太熱，電阻過大。

Check whether the shape and section of the electrode head are suitable.? The time of ordinary welding board will present the situation that the medium frequency spot welder is becoming more and more difficult to use. The first is to think that the electrode may be too hot and the resistance is too large.

焊點(diǎn)壓痕嚴(yán)重并有擠出物：

Severe indentation and extrudate on the solder joint:

指的是焊接完成以后外表燒傷嚴(yán)重，有弧坑，檢查電流能否過大或壓力能否太小，電流過大會(huì)影響焊接工件的外表焊接效果，壓力太小會(huì)呈現(xiàn)擠出物。

It refers to that after welding, the surface is severely burned and there are arc pits. Check whether the current is too large or the pressure is too small. Excessive current will affect the surface welding effect of the welded workpiece, and extrusion will appear if the pressure is too small.

焊接時(shí)容易打火，以燒焦電池外殼：

It is easy to ignite during welding, and even scorch the battery shell:

中頻點(diǎn)焊機(jī)電極壓力偏小、電極下端面粘有異物、焊接電流過大、兩電極高度不在同一水平面。

The electrode pressure of the medium frequency spot welder is too small, foreign matters are stuck on the lower end face of the electrode, the welding current is too large, and the height of the two electrodes is not in the same horizontal plane.
