Abstract
Abstract A work manipulator particularly advantageous for use in welding, cutting and like operations comprises a plurality of functionally related arms, at least a portion of said arms being respectively mounted for rotation in different planes. Means are provided for rotating said arms simultaneously or selectively as needs and to the extent required. Further means coupled to at least a portion of said arms provide as between such means and the arm to which such means is coupled a defined path of movement of one relative the other. With work holder means based on at least a portion of said arms, said arms and said coupled means are selectively or simultaneously operable to manipulate work to continuously present and move the same relative to a torch or like device at the attitude required to effect a complete continuous weld or cut with or without a change in position of the torch.
