Gas Lens Copper Brass PK2

The Miller Electric 45V44 gas lens uses copper and brass construction for TIG torch shielding gas coverage. It fits a wide range of WP, HW, PTA and PTW series torches including models 9, 20, 24 and 25. The pack contains two lenses for quick replacement on the job.

Suitable Torches and Limits

This lens suits welders running compatible Miller or Weldcraft torches who need consistent gas flow on stainless or aluminium. It will not fit torches outside the listed WP-9, WP-20, WP-24 or WP-25 families. Buyers using other brands or larger cup sizes should verify compatibility first.

3/32 Inch Electrode Size

The lens is drilled for 3/32 inch tungsten electrodes, a common size for medium-amperage TIG work. This single dimension decides whether the part matches your torch setup.

Questions about this item

How do I install the 45V44 gas lens on my WP-20 torch, and what step do people miss?

Unscrew the existing collet body, drop in the 3/32 in copper-brass lens, then reinstall the collet and back-cap; the step often missed is seating the lens fully flush before tightening the back-cap.

What maintenance or replacement will the 45V44 gas lens need over time?

Inspect the copper-brass lens for pitting or gas-flow distortion after heavy use; replace the lens if the shielding pattern becomes uneven or the threads wear on the 45V44 body.

What limit appears first when running the 45V44 lens at high amperage on a WP-24 torch?

The 3/32 in copper-brass lens reaches its thermal limit before the torch head, causing gas-flow breakdown and tungsten contamination at sustained high current.
