No Touch® Vertical Automatic Addition Tong –VAAT (NTV)
This device is designed to transport the electrode column in the vertical position to and from the furnace. The eccentric locking device will grip the electrode at the base of the socket and release the electrode once it is in the proper position. This device also has an internal stem that allows the new electrode to spin down at the same thread pitch of the existing electrode column. U. S. Patent No. 9,850,105
While using this device there will no longer be a need for a Metal Lift Plug (Addition Plug) or Graphite Lift Plug in most cases.
