DESCRIPTION

1.Welding Helmets

T-Safety welding helmets offer exceptional features, superior product warranty, and outstanding gracs at a surprisingly affordable price.

This welding helmet is equipped with an auto-darkening lens that provides a 1/20,000 second switching speed. Featuring a lightweight comfortable design with an adjustable ratcheting headband for better fit and comfort. This welding helmet gives you the full view of your welding area with a variable shade control from #9 to #13 with a resting shade of #4.

3.How do auto darkening welding hoods work?

UV OR IR Interference Filter:

The UV or IR filter comprises numerous metallic layers (5 silver layers, 6 aluminum oxide layers) and a thin glass substrate. With the help of the metallic layers, the filter has the ability to reflect and absorb 99.9% of the IR radiation within the ADL shade range. This helps to protect the wearer’s eye from harmful radiation ， also to protect the liquid crystal panels from any heat damage due to the high temperatures present during welding.

LC Liquid Crystal :

Liquid Crystal have the ability to turn the light. When lying flat, liquid crystal twist the light by 90 degrees. However, when stimulated by electricity, it is possible to manipulate how far the LCC’s bend the light.

Two polarising filters closest to the welder’s eye are aligned in the same direction， When the welding lens is switched off, the liquid crystals between the polarising filters bend the polarised light 90 degrees, meaning the lens will appear dark. This is a built-in safety feature that protects the eyes from very bright light in the event of the auto-darkening lens failing.

Conversely, when switched on, the liquid crystal between the first two polarisers un-twist the polarised light waves, causing the lens to drop down to a light shade of 3 before striking an arc. If this does not happen, do not continue welding as there is a problem with your ADL! Within 0.1 milliseconds of the arc being struck, the tosensors on the front of the lens activate the front liquid crystal panel which darkens the lens to your pre-selected dark state. The lens will then automatically return to the clear state after the weld is complete, allowing for immediate and safe inspection of the weld pool and preparation for the next weld.

4.Why is my auto-darkening welding helmet not working?

Replace Battery

Usually, a flickering side sensor light or a shaky auto-darkening filter just means you need to replace the batteries in your welding helmet. Of course, if your helmet doesn’t have replaceable batteries, then this problem most likely means you’re due for purchasing a new welding helmet. But, other than that, a simple battery replacement should fix this problem.
