  • High efficiency welding device
    Patent number: 8232504
    Abstract: The high efficiency welding device has two pairs of clamps mounted in two pairs of sliders movable in a reciprocating movement relative to one another. One pair of sliders is mounted at 0 and 180 degree positions around the circumferential surface of a support block and the other pair of sliders is mounted at 90 and 270 degree positions. Each pair of clamps is in the close condition while moving forward in the reciprocating movement to clamp onto selected air gaps of the welding electrode to advance the electrode towards the work piece as well as delivering the welding current to the welding operation, and it is in the open condition releasing the grasp of the welding electrode while moving backward.

  • Method and apparatus for forming contact gaps in continuous welding electrode
    Publication number: 20110250347
    Abstract: Circular contact gaps are formed in the welding flux coating of a continuous welding electrode by locating the electrode in a fabrication duct having the same diameter as the flux coating. High pressure air is injected at evenly spaced position of the flux coating through two air injection air ports from 45 degree angles relative to the cross sectional diameter of the fabrication duct. Contact gaps are formed in alternate consecutive sections of the welding electrode in sequential consecutive steps in which a new section of the electrode is located in the fabrication duct in each sequential step.
