Pneumatic Weld Head 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. TYPICAL APPLICATIONS Key features • 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 Power devices Laser / photonic devices Automotive components • Simple actuation using the Benchmark® SS-1 pneumatic weld head controller • Can be configured to be used with any manual or automated welding system

OPTIONAL FEATURES • Opposed electrode welding applications which require fast follow-up to prevent material expulsion • Welding ring or annular projections with a perimeter length ranging from 0.40 to 7.0 inches • Microelectronic hermetic packaging cap to header welding requiring coplanarity • Integrated glovebox systems • Vacuum - backfill options • Integrated SS-1 weld head controller • Robust design • Low maintenance • Repeatability • Worldwide support • Industry proven products • Over 30 years of welding experience HERMETIC SEALING TECHNICAL SPECIFICATIONS Part Number WEIGHT & DIMENSIONS...
