Large-diameter gas lens improves shielding-gas coverage for TIG torches accepting 1/8-inch electrodes

  • Product typeTools
  • Fits many TIG torch models including WP-9 and WP-20 series
  • Large-diameter lens improves gas coverage for cleaner welds
  • Copper and brass construction resists heat and spatter damage
  • Supports electrodes up to .125 inch for versatile welding tasks
  • Supplied as a pack of two for convenient replacement

Large-Diameter Gas Lens for TIG Torches

The Miller Weldcraft 995795S gas lens fits a wide range of WP-9, WP-20 and WP-25 series torches. It supports a maximum electrode diameter of 0.125 in for precise shielding-gas coverage during TIG welding. The copper-and-brass construction resists heat and spatter in daily shop use.

Thermal performance in normal welding

The large-diameter lens improves gas flow around the tungsten, reducing turbulence and keeping the weld pool protected at standard amperages. Copper and brass dissipate heat efficiently so the lens stays cooler during extended passes. No forced-air cooling or water circuits are required for typical applications.

Two-lens pack simplifies consumable management

The PK2 bundle supplies two identical lenses so a spare is always on hand when the first wears out. Direct compatibility with listed Miller torch models means no adapter fittings or collet changes are needed. California Proposition 65 warnings apply to the materials used in this product.

Questions about this item

How do I install the 995795S gas lens on my WP-20 torch, and what step is often missed?

Unscrew the existing nozzle and collet body, insert the large-diameter gas lens so its taper seats fully in the torch head, then reinstall the collet and nozzle; the step many skip is verifying the .125 in electrode fits the lens bore before tightening.

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

Inspect the lens screens for spatter blockage after each job, clean with a stainless brush or replace the lens if the mesh is deformed, and check the O-ring seal on the torch head whenever the nozzle is removed.

What is the first limit I will hit when running the 995795S at high amperage for long periods?

The .125 in maximum electrode diameter restricts current capacity; exceeding the electrode's rating causes overheating at the lens tip before the copper/brass body reaches its thermal limit.
