Patent ID: 7115835

Claim:
A driving system for a welding device for use with a continuous welding electrode having equally spaced flux coating sections provided on a metal core comprising: a first slidable carriage and a second slidable carriage mounted within said welding device, said first slidable carriage and second slidable carriage being movable alternately in a linear reciprocating movement, first group of gripping plates mounted on said first slidable carriage, and being operative in a closed position to clamp on said metal core at selected gaps of said welding electrode when said first slidable carriage is in an advance movement in said reciprocating movement, and alternately in an opened position to release clamping of said welding electrode when said first slidable carriage is in a rearward movement in said reciprocating movement, second group of gripping plates mounted on said second carriage, and being operative in a closed position to clamp on said metal core at selected gaps of said welding electrode when said second slidable carriage is in an advance movement in said reciprocating movement while said first slidable carriage is in said rearward movement, and alternately in an opened positions to release clamping of said welding electrode when said second slidable carriage is in a rearward movement in said reciprocating movement while said first slidable carriage is in said advance movement.
