Increasing amperage usually has more to do with metal thickness, form, purity, and other features. Steel welding processes usually involve an amperage range within 60 – 300+ amps based on certain characteristics. Metals for the process and chosen amperage range are two factors considered before selecting a lens shade level. What Shade Lens for MIG Welding is The Best? Variable shade lenses can switch within shades to accommodate a slew of demanding welding processes. Fixed shade lenses feature only one darkness level, giving them rigid eye protection support. There are two lens types on the market – fixed and variable shade lens. High-end helmets could possess four or more arc sensors. On the other hand, out-of-position welding requires improved sensor detection. Simple welding tasks in a lit environment may support helmets with two sensors. Sensors on regular helmets usually don’t exceed two. These lenses detect surrounding light and trigger shade lenses within moments.
SensorsĪrc sensors feature on helmets to assess ambient light for better shading potential. A lower denominator figure translates to a higher reaction time. Most brands in the market come with reaction times ranging from 1/36000 seconds to 1/20000 seconds. Welding helmets usually have reaction times within a fraction of a second. Time taken for these helmets to protect your vision plays a role in better welding potential and improved eye health. Variable shade lenses take a certain time to switch between regular to protective schemes. Selecting a shade one or two units should be ideal for getting your eyes used to bright light over time. But newcomers and DIY enthusiasts need to be careful with selecting shade numbers.

Such a factor may not matter to professional welders with several years of experience with arc lights. Shade lenses are the only way to avoid getting blinded by light due to choice of metalwork pieces. MetalĪrc intensity shifts are common in different metals. Engaging higher amperage makes the chances of increased arc light development more likely. Selecting a higher amperage range for your welding operation should involve getting a darker helmet shade. How Best to Pick Lens Shade Number Amperage range Since there are many dynamics attached to selecting a welding shade, getting detailed information is crucial. Welding processes could determine the ideal welding shade and could vary widely in some instances. A higher shade number translates to a darker lens. The lens shade numbers show the darkness level of your helmet and how much eye safety it can assure. Most auto-dim helmets feature built-in UV and IR protection required for better eye safety during welding. Shades represent the potential of lenses to filter rays from bright arc light capable of damaging human eyes. Shade Selection Guide Welding Shade Numbers – What Do They Mean? The right lens shade protects your eyes from any harsh contact and keeps your welding operation running smoothly.
It’s getting so rampant that there’s a condition now called welder’s eye. Most adverse lingering welding issues pros face begin with eye problems. Welders can get the required amount of vision while blotting out harmful arc light. Selecting the right welding shade for your join process proves useful in guaranteeing better eyesight.
