UltraPressure Holder
U.S. Patent Pending
TUFFALOY’S UltraPressure™ Fast Follow-Up Holder System is a low profile, spring loaded electrode holder designed specifically for new or existing resistance welding tooling that requires the additional follow-up force. Available in a range of forces from 750 to 10,000 lbs., utilizing easily replaceable dies springs to configure the holder to the weld application. These holders are especially effective for projection welding on AHSS, and in conjunction with Fast Rise Time (FRT) Transformers. UltraPressure body weighs 8.8 lbs.
The mounting must options must be ordered seperately. The UltraPressure holder can be mounted via a 5RW taper, Shank, Cylinder Mount, or a Platten Mount. Go to to the Mounting Components page in the Multi-Welding Category to view the mouting options.
