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.
