Summary: | The welding contact tips presented herein include contoured inner bores that include a front inner bore section and a back inner bore section. In certain embodiments, the front inner bore section is approximately 0.3-0.6 inches long and includes an inner wall having a substantially constant inner diameter. The back inner bore section is configured to conform to the specific welding wire used with the welding contact tip. In particular, the back inner bore section includes an inner wall having an inner diameter that is substantially larger at an axial end of the welding contact tip than at an axial transition location where the front and back inner bore sections abut. As such, the welding contact area between the welding contact tip and the welding wire is enhanced in the front inner bore section, especially when the welding wire twists inside the contact tip and the welding torch. |
