Dengensha’s new Upper Electrode Feeding unit reduces weld cycle times while promoting faster feed rates. It is capable of simultaneous workpiece movement and weld nut feeding. It has a patented new linkage design that incorporates linear as well as rotary motion, making it capable of feeding nuts accurately and at high speed. With fewer moving parts, the Upper Electrode feeding unit is more reliable. It reduces part positioning and better secures each nut. Its slim design provides application flexibility. Only one feed action is now required to both deliver and place each nut. In addition, with upper electrode feeding, the unit is capable of welding a nut to the bottom of a deep-drawn stamped part because there is no interference issue. The Upper Electrode Feeding unit has a simple universal electrode holder design capable of handling 6, 8, and 10 millimeter square nuts.
