Tweco Series 44 Conduit Liner 0.045 Wire

This Tweco 14401140 conduit liner is a new welding supply component built for Series 44 wire feeders. It fits a range of Tweco guns including Classic No. 3, Classic No. 4, Compact Eliminator and PulseMaster models. The liner guides wire from the feeder through the cable to the contact tip.

Suits owners of listed Tweco guns needing a 0.045

Welders running a compatible Tweco gun who need a replacement liner for 0.045 inch wire will use this part. It is not for machines that take a different liner diameter or a non-Series 44 design. Buyers with other gun brands or larger wire sizes should look at a different liner.

Maximum wire size 0.045 inch

The single specification that decides fit is the maximum wire diameter of 0.045 inch. This liner is made for that size only and will not feed thicker wire. Confirm your gun model appears in the compatibility list and that your wire matches this diameter before ordering.

Does the conduit get hot or noisy during all-day welding?

It is a passive PTFE liner with no moving parts, so it adds no fan noise and its temperature follows the gun handle.
