Gas lens nozzle #7L for TIG: more control and precision when welding
If you're looking for a gas lens nozzle #7L that performs well and holds up under demanding conditions, this is one I personally rely on. I use it for fine welds where I need consistent gas coverage, especially on aluminum or stainless steel parts for performance builds.
Main features
- Made of hardened alumina, resistant to heat and wear.
- Gas lens design with a wider body for improved gas coverage.
- Fits TIG torches WP-9, WP-20 and WP-25.
- Handles up to 180A DC and 150A AC with ease.
- Easy to replace on the torch, great as a consumable spare.
When to use this nozzle?
The gas lens nozzle #7L is ideal when you need more stable gas shielding, such as in tight areas or on materials sensitive to contamination. It also helps stabilize the arc on detailed welds where appearance matters.
A small part that makes a big difference
It might seem like a small detail, but a good nozzle like this one makes a huge impact on clean, porosity-free welds. Keep in mind that due to its longer body and added ceramic mass, it runs hotter than a standard #7 cup — allow it to cool if working at high amps for long periods.
Summary
A simple and reliable choice if you're after consistent TIG results. I've kept this one on hand for years when fabricating engine or chassis components where failure isn’t an option. If you're upgrading your setup or replacing worn parts, this is a solid bet.
Is it suitable for aluminum welding?
Yes, the gas lens nozzle #7L works very well for welding aluminum, especially when used with WP-20 torches with water cooling. The wider gas coverage protects the weld puddle and improves arc stability — essential when working with aluminum, which is highly sensitive to contamination and lack of shielding gas.
