How do you clean welding lenses?
In respect to this, what shade of lens should be worn when welding?
Welding lens shade numbers refer to the lens' ability to filter light¾all auto-darkening welding helmets meeting ANSI Z87.1 provide 100% protection against harmful infrared and UV rays¾ and may range from a #8 shade for low-amp applications up to a #13 shade for high-amp applications.
Subsequently, question is, what is the best way to clean aluminum for welding? Take the following steps before welding aluminum: 1. Remove oil, grease, and water vapor using an organic solvent such as acetone or a mild alkaline solution like a strong soap. You may also use citrus-based degreasers, but be sure to rinse and dry the part before welding.
Just so, how often should I change my welding lens?
Typically, you should only need to replace it once a month, though again this will vary from welder to welder. Put simply, the lens should be replaced whenever it incurs damage or when visibility starts to decrease.
Are all welding helmets the same?
When work is complete, the welder has to lift the helmet to see. However, if most of your welding tasks only involve one kind of material, at the same thickness, and if you're always using the same process at a fixed amperage, then there's really no need to buy anything more than a fixed shade #10 standard helmet.
