KN-200A Single Force Pneumatic Weld Head – Opposed Electrodes

The KN-200A-Single weld head has been extensively proven in industrial environments around the world and is regarded as the "dependable workhorse" of the industry. Its proprietary fast force follow-up feature eliminates weld expulsion, preventing entrapment of ejected materials in projection welded electronic devices - a common cause of PIND (particle impact noise detection) failure.

Single cylinder design delivers 250 – 1250 lb (113 – 568 kg) of weld force.

Designed to accommodate a variety of metal projection welding applications including sensors, frequency devices, filaments, heating elements, photonic packages, strain gauges and transducers.

  • Robust, low maintenance die set design
  • Fast force follow-up feature maintains force during weld eliminating weld expulsion
  • Rigid construction using a 25 micron matched linear ball b...
