Compatible Conduit Liner

The Tweco 14201125 is a copper threaded conduit liner sized at .045 inches. It is designed for use with Series Classic No. 1 and No. 2 guns as well as Spray Master 250 and WeldSkill WM 250 models. This part feeds welding wire smoothly through the gun assembly.

Steady Wire Feed Performance

The copper construction provides consistent electrical conductivity during extended welding sessions. It resists heat buildup that can cause wire feeding interruptions under sustained load. The threaded design maintains a secure connection throughout long production runs.

Verify Gun Series Compatibility

Confirm your welding gun is a Series Classic No. 1, Classic No. 2, Spray Master 250 or WeldSkill WM 250 before ordering. This liner will not fit guns outside those designated series. Check your existing liner diameter matches the .045 inch specification.

Questions about this item

Does the copper conduit itself add any heat or noise during continuous welding?

The conduit is a passive copper liner; it does not generate heat or noise, though the welding process and wire feeder will produce normal operating heat and sound.

Which wire feeders or guns must I already own for this .045 liner to fit?

It is compatible with Tweco Classic No. 1, Classic No. 2, Spray Master 250 and WeldSkill WM 250 series guns.

Will this .045 liner work with older Tweco guns I already have?

Yes, it fits the Classic No. 1 and Classic No. 2 series, which are earlier Tweco gun models.
