I’ve been using the HEIR 1.0 autodarkening lens for a while now, and it’s been a great upgrade. The optical clarity is excellent, making it much easier to see the weld puddle and overall joint compared to the standard lenses I’ve used before. The lens reacts quickly and has performed reliably every time I’ve welded. I’ve used it for Stick, MIG, Flux Core, and TIG. It performs really well across all of those processes, and the improved visibility has definitely helped me become a better welder. For anyone who does a lot of TIG welding, Ridge Products recommends their HEIR 2.0 series lenses because they’re specifically optimized for TIG. That’s actually the next lens I plan on purchasing. But for an all-around lens, the HEIR 1.0 has exceeded my expectations, and I’d definitely recommend it to anyone looking to upgrade their welding experience.
