Ridge Products’ Red Welding Lens: The Best Choice
You know what it's like. You're working on a major project, and your lens isn't delivering. That's where our Duke red welding lens really shines. What makes it stand out is how clear its vision is. It keeps your eyes safe and offers you a great vision, so you can create cleaner welds with fewer mistakes. It’s like having an HD screen right in your hood.
Our red welding lens lasts, and the battery lasts up to 1600 hours. That's a lot of time for welding, so you won't have to worry about your gear breaking down when you're in the zone.
TIG Welding? Read This First
Our Duke lens is wonderful for TIG welding, but there's a small detail you should know. This lens may flash when you TIG weld at currents below 90 amps. We strongly recommend our King 2.0 lens for this type of low-amperage TIG welding because it’s specially rated for the job. The Duke is a great choice for all other types of TIG work.
Frequently Asked Questions
Category
There are sensors in auto-darkening lenses that can see the bright flash of a welding arc. When the sensors go off, the lens changes from a clear, bright state to a dark, protective shade in less than a second. This rapid change keeps your eyes safe from UV and infrared light that can be harmful when welding.
With an adjustable shade lens, you can select the ideal shade level for various welding jobs and amperage settings. This means that you can use one lens for a range of applications, from plasma cutting (lower shades) to high-amperage flux-core welding (higher shades). This will give you the best visibility and protection for every work.
There are a few things that could cause this. A dead battery or a sensor that’s blocked by something within the helmet are the most typical problems. First, check the batteries. Then, make sure the sensors on the front of the lens are clean and can see the welding arc well.
The shade number you need depends on the type of welding you’re doing and the amount of amperage you’re using. Generally, a higher amperage requires a darker shade. For instance, a shade 9 or 10 could be adequate for MIG welding with low amperage, whereas a shade 12 or 13 might be needed for heavy-duty Stick welding.
You may press a "test" button on most auto-darkening lenses, like The Duke, to make sure they are operating correctly. You can quickly test your lens by striking an arc on a scrap piece of metal if it doesn't have a test button. Before starting a new project, ensure your eyes are protected by checking your lenses.
