Projection Cap Weld System - Pulsar, RP3000

Projection Cap Weld System - Pulsar, RP3000

 

  • Short duration weld pulse enables low energy welding and repeatable precise projection weld results
  • Ultra-fast rise times for high throughput weld cycles over a broad range of applications

 

The Pulsar  (P-1000, P-3000, P-6000, P-9000) resistance welding power supply and high-efficiency weld transformers may be combined with a KN weld head to form a single station projection cap welding system. 

Production proven in industrial environments around the world, these systems are the dependable workhorses of the industry. Whether hermetically sealing micro-electronic packages, transistor outline packages, or joining a variety of metal parts, Pulsar’s broad range of precision power choices provide technically advanced process solutions. 

Pulsar can be easily integrated into atmospheric enclosures to insure high yield hermetic sealing results, or outfitted with aninnovative electrode vacuum and gas backfill system for electronic package sealing that enables packages to be evacuated, and then filled with gas before being hermetically sealed.
