  • Welding diffuser with debris removal
    Patent number: 9527155
    Abstract: A welding diffuser and contact tip assembly is provided for use with a welding apparatus. The assembly includes a diffuser with an interior chamber and a plurality of openings defining exit passages from the interior chamber to an exterior of the diffuser, and a contact tip coupled to the diffuser. The contact tip includes a front portion, a rear portion, and a contact tip bore extending therethrough configured to receive electrode wire. A diffuser insert is disposed within the interior chamber of the diffuser, including an insert bore extending therethrough configured to receive electrode wire, and an angled outer surface configured to direct debris from within the interior chamber of the diffuser towards exit passages to thereby discharge the debris to an exterior of the diffuser. In one example, the rear portion of the contact tip includes an angled outer surface defining the diffuser insert.
