Miller Gas Lens Copper Brass

This Miller Electric gas lens is a copper and brass consumable designed for TIG welding torches. It fits electrode diameters from .020 to .040 inches and comes in a pack of two. The component is compatible with a wide range of torch models including the 17, 18 and 26 series.

Suitable for TIG welders using compatible torches

Welders operating Model 17, 18 or 26 series torches such as WP-17, WP-18 or WP-26 variants can use this gas lens. It is not intended for operators using torch models outside the listed compatibility range or for processes that do not require a gas lens.

Electrode range .020 to .040 inches

The lens accepts tungsten electrodes between .020 and .040 inches in diameter. This specific range determines whether the part matches the electrode size required for the current welding application.

Questions about this item

How is the 45V0204 gas lens installed on a WP-17 torch, and what step is often missed?

Unscrew the existing nozzle and collet body, drop the lens into the torch head, then reinstall the collet body and nozzle; the step often missed is seating the lens fully flush before tightening the collet body.

What maintenance will the copper-brass gas lens need over time?

Inspect the fine-mesh screen for spatter buildup or deformation; clean with a soft brush or replace the lens if the mesh is torn or the copper shows heavy discoloration.

What limit appears first when running a WP-26 at high amperage with this lens?

The torch body’s duty-cycle rating is reached before the gas lens itself becomes a restriction.
