CYBER WEEK 30% OFF ENTIRE STOE CODE: 30CYBER ENDS: 11/28/2023, AT 11:59 PM ET
Our welding lenses include cobalt blue and athermal green lenses, which can be purchased as welding glasses. Besides these, our selection also contains alloweld lens, clear glass cover lens, gold welding lens, super blue drop in lens, super magenta drop in lens, and welding magnifier lens.
Here we offer flat lenses for goggles, helmets, and masks in standard sizes and shades. We also have standard welding shades with added protection from sodium flare for working with cast iron, aluminum, and stainless steel. Phillips Safety’s standard lens sizes are also available with a gold mirror for added heat protection, and all of our welding glass is the highest quality German glass, with no bubbles, striation, or optical distortion. In addition, Phillips Safety’s welding lenses are available in rectangular and circular shapes, with different sizes. Both standard and custom sizes and shapes are available upon request.
Welding lens work by filtering out harmful radiation emitted during welding. When you weld, the welding arc produces a bright light that can damage your eyes if you’re not wearing proper eye protection. Welding lens are designed to block out the UV and IR radiation while still allowing visible light to pass through. The welding lenses are made of a special material that filters out specific wavelengths of light, providing different levels of protection.
Passive lenses work by using a fixed shade level to filter out the light. The higher the shade level, the darker the lens will be. Auto-darkening lenses work by using sensors to detect the bright light from the welding arc. When the sensors detect the light, they send a signal to the LCD display, which darkens the lens within milliseconds. Once the arc is extinguished, the lens returns to its normal, clear state.
Determining the welding shade that is best for you depends on several factors, such as the welding process, the material being welded, and the amperage or power level of the welding equipment.
In other words, your choice of welding shade should depend upon the type of welding you’re doing, and there is typically a range of accepted shades so there is some room for personal preference.
OSHA provides guidelines for the minimum shade level required for various welding processes, materials, and amperage levels. Consult safety guidelines and regulations here.
