Abstract
Systems and methods are described to address issues associated with welding with cored wires. In certain processes, a welding wire may 'stick' or fuse to a contact tip, such as at termination of a weld. To mitigate the negative effects of a wire fusing to a contact tip, the wire remains in motion at a time prior to the end of the weld, as the weld ends, and/or for a time after the end of the weld, to limit and/or eliminate fusion between the wire and the contact tip.
