Beschreibung
Zusammenfassung:	An electric welder features that an electric accumulator set is used as its stand-by power supply, which can supply electric energy to the electric welder via the DC-DC converter with constant current characteristics. Its advantages are small size, light weight and no rotational abrasion. 本发明属于电子技术领域,在没有市电的场合，一般采用发电机组发电，再供给电焊机，这种方式体积大、笨重。本发明使用蓄电池作为电源，经过恒流特性的直流一直流变换器变换后供焊接使用，具有体积小、重量轻、无旋转磨损等优点。
