Miller Enterprises 17CB20 Collet Body Copper .040-1/8 PK2

Miller 17CB20 Collet Body Overview

The Miller 17CB20 is a copper collet body supplied as a pack of two. It fits a wide range of TIG torch models including the 17, 18 and 26 series and handles electrode diameters from .040 to 1/8 inch. The stubby design suits welders who need a compact torch head for tight joint access. Copper construction provides reliable electrical conductivity and heat dissipation during welding.

Compatibility and Limitations

This collet body is intended for TIG welders using compatible Miller or WP-series torches listed in the specifications. It will not fit torches outside those model families, so buyers with different torch brands or larger electrode requirements should look elsewhere. The pack contains two bodies only; no collets, gas lenses or other consumables are included. Users needing a complete consumable kit must source the remaining parts separately.

Sustained Load Behaviour

Copper conducts heat efficiently, helping the collet body maintain stable electrical contact during extended welding cycles. The stubby profile reduces mass, which can lead to faster heat saturation compared with longer bodies under continuous high-amperage work. Periodic inspection for wear or deformation is advisable when the torch is run at upper current limits for long periods. Proper torch cooling and correct electrode sizing help sustain performance over time.
