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

Formerly known as KN-II

The KN-200A weld head has been extensively proven in industrial environments around the world and is regarded as the “dependable workhorse” of the industry. Built in the USA the KN-200A and 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.

Dual cylinder design delivers 250 – 4082 lb (113 – 1855 kg) of weld force.

Designed to accommodate a variety of metal projection welding applications including sensors, frequency devices, filaments, heating elements, photonics 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 mi...
