So, you need to know your applications clearly before going to spend on helmets. The fixed lens can be significantly cheaper as compared to variable ADF helmets. If you are going to work with just one material, then choosing a fixed shade helmet is not a bad idea. The primary decision for your choice depends on the application and the material you are going to weld. This also has the advantage of allowing you to weld more than one material and also adjusting the tools and workpiece without having to remove the helmet. On the other hand, a variable shade helmet has a lens color, which can vary from application to application. While working with a fixed shade lens, you will require to put off your helmet to adjust your workpiece. You can choose this number according to the application. The fixed shade lens will provide a predefined shading of one level. The decision between fixed and variable shade lenses is essential. Choice of the number depends particularly on the job you are dealing with. Such that for the amperage of 300, you will wear a DIN number of 13. This number increase with the increase in the amperage rating. For STICK welding of below 100 Amps, you can wear an arc welding lens of 10. STICK welding has similar parameters to TIG welding and you can use the same numbers of shade for it. For even greater amperage ratings, a welder can choose shade number 13 or 14 as per need. Similarly, for larger amperage ratings of up to 300 amps, you can use a shade number of 12. For welding metals up to 175 Amps, you can use a shade number of 11. For lower amperage ratings like 80 to 100 Amps, you should use a shade number of 10. The value of the number increase with an increase in the amperage rating. MIG Weldingįor MIG welding, you can use a number of lens shades. A TIG weld is usually done on thinner welds and by using a shade lower shade number, you will get enough light to view the workpiece and protection while applying welds. If you have a task with greater ampere ratings of up to 100 Amps then you can use a shade of 9 or 10 respectively. Most of the welders recommend a shade number of 8 for TIG welding below 50 Amps. Usually, a lower shade number is sufficient when working with TIG welding. Welding Shade for Different Welding Jobs TIG Welding Finally, you will need that your helmet meets the location ANSI Z87.1 standard and choose a shade that is referred to for your task. Similarly, this number increases with an increase in amperage rating.ĭIN number 12 is ideal for arcs ranging from 160 to 200 amps, 13 for the range 200 to 240 amps, and for the welding over 250, a shade number of 14 is usually recommended. For a welding job dealing with arcs of the range 60 to 160 Amps, you should choose a DIN shade number of 11. The welder’s eyesight is also an essential factor here however, we suppose the results for ideal vision. According to OSHA, welding work ranging from 50 to 60 amps requires a shade number of at least 10. The shade of lens suitable for your job depends on the amperage rating of your weld. Thus, the lens shade number you want directly depends on the type of job you are dealing with and the brightness of your welding arc. Most times, the weld arcs have a brightness of more than the sun, then you will need a lens shade number of 9, which provides light transfer of just 0.037% or, forever severe conditions, you can choose shade numbers that are as high as 13 which has a transmission rate of 0.00072%. This shade number is useful if you work in dim light areas usually. With a DIN shade of 4, you will get only 5% light transfer. A DIN shade level of 3 provides a visible light transfer of 14%. As the DIN number increases, the shade of the lens becomes darker. The DIN numbers are according to German Industrial Standards used to classify the light filtering number.
