Abstract
Official abstract text for this publication.
A contact tip is provided for wire welding applications. The contact tip includes one or more conductive brushes fitted to a conductive contact tip body. Fibers of the brush extend into a passageway traversed by welding wire in operation. Electrical current is transmitted to the brush assembly and through the brush fibers to the welding wire. The fibers may transmit the current directly and also may enhance contact of the welding wire with one or more walls of the contact tip. Improved electrical contact and weld quality are obtained.
First claim
Opening claim text (preview).
The invention claimed is: 1. A welding contact tip comprising: a conductive body configured to be secured within a welding torch and to receive a welding wire through a longitudinal aperture formed through the body; and a conductive brush having fibers extending into the longitudinal aperture and configured to transmit electrical current to the welding wire in operation; wherein the fibers are configured to exert a lateral force on the welding wire to drive the welding wire in…
