1. A gas diffuser for use in a welding application, comprising:
a seat configured to retain an outer surface of a contact tip within a gas flow path on an interior of a front end of the gas diffuser, wherein the seat is defined by a plurality of teeth that extend from an interior surface of the gas diffuser toward a longitudinal axis of the gas diffuser, wherein each tooth comprises a shelf configured to abut a rear-facing surface of the contact tip, and wherein the gas flow path extends through channels that are between the teeth along the outer surface of the contact tip when the contact tip is retained within the gas diffuser.
