Projection Weld Head – KN-II

• 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 bearing bushing and tie rod for precise positioning and planarity
• Simple actuation using Benchmark’s SS-1 pneumatic weld head controller
• Can be configured to be used with any manual or automatic welding system

The KN-II 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.

Dual cylinder design delivers over 4000 lbs 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.
