Copper Collet Body for 1/16 In Electrodes

This pack of five copper collet bodies fits Miller Weldcraft TIG torches in the 17, 18 and 26 series. Each body holds a 1/16 inch tungsten electrode and conducts shielding gas through the torch head. The copper construction resists heat during extended welding cycles.

Suits welders maintaining compatible torch models

Technicians who own WP-17, WP-18, WP-26 or related PTA and HW series torches can use these replacements directly. Shops running torch models outside the listed 17, 18, 26 and A-series families should verify fitment before ordering. Buyers needing a different electrode diameter must select the matching collet body size.

Critical spec: 1/16 inch electrode compatibility

The collet body is machined for 1/16 inch tungsten only; using a larger or smaller electrode will not seat correctly and will compromise gas sealing. Confirm the torch model number against the compatibility list before installation. The pack contains five identical bodies for workshop spares.

Questions about this item

How often do I need to replace the copper collet body on my WP-17 torch?

Replace the collet body when the bore shows visible wear or the electrode no longer seats tightly; copper softens with heat cycles so inspect it each time you change the 1/16 in tungsten.

What stops me from welding continuously with this 10N31 body on a WP-26 torch?

The copper body itself has no duty-cycle limit; the torch head and power source ratings — 150, 200, 250, 350 or 410 amp models — determine how long you can run before overheating.

Does the collet body get hot enough to burn my hand during all-day TIG work?

The body conducts welding current directly, so it reaches workpiece temperature; always wear a TIG glove and let the torch cool between long beads on 18, 26 or 17 series torches.
