IGBT逆变高精密电阻焊机的特点：
1、四种控制方式：有[3次定电流] [3次定电压] [3次定功率] [3次定脉宽] 4种控制方式可以找到**合适的焊接条件。
2、直流输出。直流焊接提高了焊接热效率，使得不受电感性负载的影响，可以流通大电流。对有色金属材料和一些难焊材料的焊接特别适合，焊接过程稳定、焊接质量显著提高。
3、响应速度快。通电时间控制周期≤0.25ms，比通常焊机的20ms提高80倍以上，与电容储能焊机相比，可控性明显增强，特别适合于精密件的焊接和高质量、高精度、高速度焊接。
4、采用微机控制，保证工艺的一致性。多组焊接工艺参数存储，参数调整与焊接循环面板直观指示，简化操作。
5、三相负载平衡（三相输入机型），功率因素高。
6、节能，电流损耗是传统焊机的2/5。达到同等焊接效果时，峰值电流可以很低。
7、体积小、重量轻。适合于机器人应用。
8、三段通电，每段通电时间、电流、电压、功率、脉宽大小可单独调节。前后两段具有缓升和缓降功能，便于抑制焊接飞溅，可获得稳定高品质的焊接效果。
9、可分别监测各段通电的电流、电压、功率、脉宽（平均有效值）
10、通电时间短、热效率高、焊接成型美观。
11、适用于钛、镍、铝、镁、钼、钽、铌、银、铂、锆、铀、铍、铅等合金料，不锈钢、铜、铁、白金、黄金、K黄金、K白金、银等贵金属的高质量焊接。
可配套在点焊、碰焊、对焊、缝焊的场合。
