Abstract
A welding device that facilitates depositing of a welding bead on a surface to be built-up. The welding device includes a housing accommodating a rotatable spindle therein, a drive mechanism coupled to the spindle to facilitate rotation thereof, and a second rider circumscribing the spindle and supporting a second gripper member. The second gripper member surrounds the spindle and allows the second rider to move axially with respect to the spindle in one direction but prevents axial movement of the second rider with respect to the spindle in an opposite direction. A first rider also circumscribes the spindle and is located between the driven mechanism and the second rider. The first rider supports a first gripper member that surrounds the spindle and allows the spindle to move axially with respect to the first gripper member in one direction but prevents axial movement of the spindle with respect to the first gripper member in an opposite direction. The second rider, when the second gripper member is in an operative position, induces axial movement of the spindle upon rotation thereof.
