IGBT逆變高精密電阻焊機(jī)的特點(diǎn)：
1、四種控制方式：有[3次定電流] [3次定電壓] [3次定功率] [3次定脈寬] 4種控制方式可以找到最合適的焊接條件。
2、直流輸出。直流焊接提高了焊接熱效率，使得不受電感性負(fù)載的影響，可以流通大電流。對(duì)有色金屬材料和一些難焊材料的焊接特別適合，焊接過(guò)程穩(wěn)定、焊接質(zhì)量顯著提高。
3、響應(yīng)速度快。通電時(shí)間控制周期≤0.25ms，比通常焊機(jī)的20ms提高80倍以上，與電容儲(chǔ)能焊機(jī)相比，可控性明顯增強(qiáng)，特別適合于精密件的焊接和高質(zhì)量、高精度、高速度焊接。
4、采用微機(jī)控制，保證工藝的一致性。多組焊接工藝參數(shù)存儲(chǔ)，參數(shù)調(diào)整與焊接循環(huán)面板直觀指示，簡(jiǎn)化操作。
5、三相負(fù)載平衡（三相輸入機(jī)型），功率因素高。
6、節(jié)能，電流損耗是傳統(tǒng)焊機(jī)的2/5。達(dá)到同等焊接效果時(shí)，峰值電流可以很低。
7、體積小、重量輕。適合于機(jī)器人應(yīng)用。
8、三段通電，每段通電時(shí)間、電流、電壓、功率、脈寬大小可單獨(dú)調(diào)節(jié)。前后兩段具有緩升和緩降功能，便于抑制焊接飛濺，可獲得穩(wěn)定高品質(zhì)的焊接效果。
9、可分別監(jiān)測(cè)各段通電的電流、電壓、功率、脈寬（平均有效值）
10、通電時(shí)間短、熱效率高、焊接成型美觀。
11、適用于鈦、鎳、鋁、鎂、鉬、鉭、鈮、銀、鉑、鋯、鈾、鈹、鉛等合金料，不銹鋼、銅、鐵、白金、黃金、K黃金、K白金、銀等貴金屬的高質(zhì)量焊接。
可配套在點(diǎn)焊、碰焊、對(duì)焊、縫焊的場(chǎng)合。
