Abstract
A contact device for feeding current to one or more welding wires in a welding apparatus includes a split tip nozzle having first and second diametrically opposed slots formed therein and a biasing means for supplying an adjustable biasing force to first and second split tips to bias the first and second split tips together to ensure that a desired contact between the split tip nozzle and the one or more welding wires is maintained throughout the lifecycle of the nozzle. The biasing force may be applied by any means including, for example, a compression ring, interaction of tapered surfaces between the tube and the split tip nozzle, a compression or cylinder spring pre-mounted on the first and second split tips, a tensioning screw, etc.
