一、簡介

電容儲(chǔ)能點(diǎn)焊機(jī)，利用工頻交流電經(jīng)整流器整流后向電容器充電，被存儲(chǔ)的電能再經(jīng)焊接變壓器放電轉(zhuǎn)換成低電電壓的、能量比較集中穩(wěn)定的脈沖電流，通過被焊工件的接觸點(diǎn)產(chǎn)生電阻熱將金屬熔接。

相較于普通工頻 50Hz 交流控制器，具有如下優(yōu)點(diǎn)：

1、節(jié)能高效；

2、對(duì)電網(wǎng)的需求低，不僅體現(xiàn)在大功率焊機(jī)僅需小功率電網(wǎng)，還體現(xiàn)在電網(wǎng)的波動(dòng)對(duì)其影響也小；

3、焊點(diǎn)熱影響小，不變色、變形；

4、強(qiáng)規(guī)范焊接，極其適合凸焊，包括多點(diǎn)凸焊、環(huán)凸焊（密封性要求）、高強(qiáng)度鋼。

二、技術(shù)特點(diǎn)

1、充放電速度快：高性能微處理器控制充放電，改變傳統(tǒng)延時(shí)繼電器的控制方式，極大提高充放電速度。不需要升壓變壓器，20ms即可完成閃充。

2、不挑電容：傳統(tǒng)控制電路在電容老化后由于其充放電特性變壞而無法正常工作，本控制器采用全新控制方式，新舊電容在不損壞前提下都可正常工作，延長電容使用壽命。

3、不燒模塊和限流電阻：多重檢測(cè)確保不出現(xiàn)充放電模塊同時(shí)開啟導(dǎo)致燒壞模塊和電爐絲現(xiàn)象。即便在放電可控硅因故障或老化而短路時(shí)，控制器也可以自動(dòng)進(jìn)入保護(hù)模式保證電路的安全。

4、電容電壓自動(dòng)調(diào)節(jié)：控制器自動(dòng)對(duì)電容泄漏電流進(jìn)行補(bǔ)償以保證電壓恒定。手動(dòng)設(shè)置焊接電壓時(shí)，電容電壓自動(dòng)隨設(shè)置的焊接電壓值做相應(yīng)調(diào)節(jié)。

5、故障檢測(cè)及告警功能：可自動(dòng)檢測(cè)焊機(jī)故障并告警。告警包括充電故障告警、放電故障告警、電壓過充告警和存儲(chǔ)錯(cuò)誤告警。

6、可存儲(chǔ)64組規(guī)范：可以存儲(chǔ)64組焊接規(guī)范供用戶使用。

7、4位焊接計(jì)數(shù)：焊接時(shí)自動(dòng)計(jì)數(shù)，范圍0~9999，手動(dòng)清零。

8、電容電壓實(shí)時(shí)檢測(cè)：實(shí)時(shí)檢測(cè)電容電壓，不到設(shè)定電壓值不放電。誤差≤1%。

9、可對(duì)焊接時(shí)間進(jìn)行預(yù)設(shè)定，可設(shè)置焊接時(shí)間，焊接電流，逆變頻率，焊接壓力，對(duì)于特定焊接材料尤其是熱成型板高強(qiáng)鋼等，讓焊接工藝更輕松。
