The present invention relates to a micro-welding technology and micro-welding machine which emerge for first time in resistance-welding field and mainly find their applications in the welding of tiny work pieces that can be processed only with the assistance of microscopic optical devices, such as the welding of leading pad of enameled wire during manufacture of kinds of electronic components having coils of small diameter. A micro-welding machine includes a main power supply, a welding head and a headstock. The main power supply includes a resistance welding transformer and a power supply controller; the main power supply outputs step-wave pulse through the power supply controller during welding process and, during welding process, the headstock connects an output portion of the resistance welding transformer to the welding head. |
