Micro-welder

摘要

A micro-welder, by which a superfine wire such as a lead wire can be welded on a desired position of a parent material with a minimum welding area, including: a power source having a capacitor-charging device for generating a predetermined voltage and a voltage controller for adjusting the level of voltage output from the capacitor-charging device; a charge-storing member connected in parallel to the power source for storing the voltage output from the capacitor-charging device; a switching member connected in parallel to the charge-storing means for conducting the voltage output from the capacitor-charging device; a switch driving member for turning-on the switching member; and a welding circuit connected in serial to the switching member.
