Abstract
A welding system, in certain embodiments, includes a torch having a neck with an arcuate portion, and a resilient jump liner disposed in the neck and extending through the arcuate portion. The resilient jump liner includes a pathway having a curvature configured to bend a welding wire passing through the pathway. The system also includes an annular support disposed about the resilient jump liner inside the neck, wherein the annular support is configured to at least substantially fix the curvature to force the welding wire to achieve a wire curvature. The system also includes a contact tip coupled to the neck, wherein the wire curvature is configured to bias the welding wire into substantially consistent contact with an interior pathway through the contact tip.
