October 29, 2018 - AMADA MIYACHI AMERICA INC., Monrovia, California, manufacturer of resistance welding, laser welding, marking, cutting, and micro machining equipment and systems, highlights the KN-II Series Pneumatic Weld Head, a robust, low maintenance weld head ideal for opposed electrode welding applications that require fast follow-up to prevent material expulsion. The KN-II is also a good choice for welding ring or annular projections with a perimeter length ranging from 0.40 to 7.0 inches and for microelectronic cap welding applications requiring co-planarity. Extensively proven in industrial environments around the world, the KN-II is used to weld sensors, frequency devices, filaments, heating elements, photonics packages, strain gauges, transducers and more.

With its proprietary fast force follow-up feature, this dependable weld head eliminates weld expulsion, preventing entrapment of ejected materials in projection welded electronic devices – a common cause of particle impact noise detection (PIND) failure.

The KN-II features a dual cylinder design that delivers more than 4000 pounds of weld force. With a robust, low maintenance die set design, the weld head boasts rigid construction using a 25 micron matched linear ball bearing bushing and tie rod for precise positioning and planarity. It can be configured for use with any manual or automated welding system and offers simple actuation using the Benchmark™ SS-1 pneumatic weld head controller.

This weld head is most frequently paired with AMADA MIYACHI Pulsar Series capacitive discharge power supplies or IS Series inverters. Optional features for the KN-II series include integrated glovebox systems, vacuum-backfill options, and an integrated SS-1 weld head controller.
