When should I replace my welding helmet 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.

What is the purpose of the filter lens in a welding helmet?

1) UV/IR Interference Filter: This helps to not only protect the wearer’s eye from harmful radiation, but also to protect the liquid crystal panels from any heat damage due to the high temperatures present during welding.

How do you test auto darkening welding helmet?

A simple way to test an auto-darkening welding helmet is to use a torch strike that is used to light an oxy-acetylene torch. Use the striker and create some sparks. The sensor of your welding helmet should instantly notice the sparks and your helmet should switch to dark mode.

Can you wear glasses under a welding helmet?

Welding helmets are specifically designed to wear glasses under them. These adjustable protective items are more than capable of accommodating safety glasses underneath them. In light welding situations, consider using welding glasses instead of a full helmet and safety glasses.

Why are safety glasses required when welding?

Clear safety glasses should be worn underneath a welding helmet when welding — the safety glasses will protect the eyes from sparks or other debris, while the shaded helmet prevents eye damage that could be caused by the ultra-bright arc. In grinding and cutting situations, shaded safety glasses may be required.

Should you remove your helmet while welding Why?

Remove your helmet while welding. You must always wear your helmet when welding and when in the vicinity of another welder. While the intensity of the radiation produced decreases the further you are from a welding arc, those less than 10 metres away are still susceptible to arc-eye.

What is Din on welding helmet?

What does the welding lens shade number mean? The DIN rating is a German industrial standard used to classify light filtering levels. As the DIN number increases, the lenses become darker and block more light. Most auto-darkening lenses have a passive base level of DIN 3 or 4.
