摘要:
A contact tip for a welding torch in accordance with the present invention includes an elongated, generally cylindrical body having a front contact end and an opposite rear retaining end. A central aperture is defined by an inner wall of the body. The aperture extends through the body from an opening at the rear retaining end to an opening at the front contact end. The aperture has a front portion and a wider diameter portion adjacent the front portion. The front portion generally has a length that is shorter than a length of the wider diameter portion. A consumable electrode wire fed through the aperture contacts the inner wall in the front portion but does not contact the inner wall in the wider diameter portion.
