Patent ID: 8232504

Claim:
A high efficiency welding device for a continuous welding electrode having equal length welding flux coating sections separated by evenly spaced consecutive air gaps exposing a metal core within said electrode, comprising: two pairs of clamps mounted within two pairs of sliders, a first pair of said sliders being slidably mounted within first two tracks formed on a circumferential outer surface of an elongated support block, said first two tracks being located directly opposite to one another and lying in a first plane perpendicular to the longitudinal axis of said support block, a second pair of said sliders being slidably mounted within second two tracks formed on said outer surface of said elongated support block, said second two tracks being located directly opposite to one another and lying in a second plane perpendicular to both said first plane and the longitudinal axis of said support block; a central opening formed in the longitudinal axis of said support block operative for receiving said continuous welding electrode to pass through said device; two coupling members movable in a back and forth reciprocating movement relative to one another, one coupling member being connected to said first pair of sliders and a second coupling member being connected to said second pair of sliders; first pair of clamps of said two pairs of clamps being located in said first pair of sliders, and a second pair of clamps of said two pairs of clamps being located in said second pair of sliders, said first pair of clamps and said second pair of clamps being located alternately at a front position and rear position relative to one another in said reciprocating movement, and alternately grasping on said welding electrode while moving forward to said front position, and releasing the grasp on said welding electrode while moving rearward to said rear position.
