APPARATUS FOR ELECTRIC CONTACT SPOT WELDING, PREFERABLY OF SMALL-SIZE PARTS

摘要

The present invention relates to apparatus for electric contact welding, preferably, of small-size parts, wherein a movable rod supporting the top electrode holder is connected through at least one leaf spring to a mechanism adapted to develop a contact welding pressure. The end of this leaf spring is rigidly secured to the mechanism adapted to develop the contact welding pressure and the other end of this leaf spring freely bears upon the rod supporting the top electrode holder. The high-current electric conduit which supplies the welding current to the top electrode holder has a portion, adjacent to the top electrode holder, which extends perpendicularly to the housing of the bottom electrode holder.
