COBRA CUT® These zinc-coated wire electrodes were initiallyproduced for AGIE for their first AC machines. Due to its high elongation, it is particularlysuitable for high tapering. It has a limited suitability for machine models with automatic water-jet threading. COBRA CUT® Type D This wire electrode has been developed for EDM machines with high-power generators. It has a high thermal and electrical conductivity due to its special coating, making it suitable for speed cutting as well as contour precision cutting. This wire electrode may also be used on machines with automatic threading.
