Miller Weldcraft 10N30 Collet Body

The Miller Weldcraft 10N30 is a copper collet body designed for TIG welding torches. It is sold as a pack of five pieces. This component fits a wide range of Miller torch models including the 17, 18 and 26 series. It is intended for welders who need to replace worn collet bodies on compatible equipment.

Fit for 0.040 In Electrodes on Listed Torches

This collet body accepts 0.040 inch tungsten electrodes. It suits operators using any of the listed torch models such as WP-17, WP-18, WP-26, PTA-17 or PTA-26. It will not fit torches outside the compatibility list or electrodes of a different diameter. Buyers with other torch series or electrode sizes should look for a different collet body.

0.040 Inch Electrode Compatibility

The critical specification is the 0.040 inch bore size matched to the tungsten electrode. The part number 10N30 confirms the correct replacement for the compatible torch series. Verify your torch model against the list before ordering. This ensures the collet body seats properly and holds the electrode securely.

Questions about this item

How do I install the 10N30 collet body on my WP-17 torch, and what step is often missed?

Unscrew the old collet body from the torch head, insert the new copper 10N30 body, and tighten it securely; the step many miss is seating the matching .040 collet inside before final tightening, otherwise the tungsten will not be held concentrically.

What maintenance or replacement will the 10N30 collet body need over time?

Inspect the copper body for pitting, cracking or thread wear after heavy use; replace it when the bore no longer grips the .040 collet tightly or when gas leakage appears around the threads.

What limit appears first when running the 10N30 collet body at high amperage on a WP-26 torch?

The copper body reaches its thermal limit before the torch head, causing the collet-to-body interface to loosen and gas coverage to degrade during sustained high-current welding.
