1. A replaceable liner for use in a welding torch assembly comprising:
a liner guide;
a section of liner inserted within a section of the liner guide,
wherein prior to being locked in place by a locking feature of a rotating gooseneck, a tapered end of the liner guide is in contact with a receiving member of the welding torch assembly, and
when the rotating gooseneck is locked in place, a gap is formed between the tapered end and the receiving member to prevent an electrical conduction between the receiving member and the liner guide; and
at least one sealing feature positioned adjacent the tapered end and the at least one sealing feature is configured to permit rotation of the replaceable liner independent of the welding torch assembly and prevent the replaceable liner from being twisted relative to the welding torch assembly.
