What is a Welding Helmet?
Welding is a task that needs to be done with due care and precautions. It is very crucial
to protect yourself with all the accessories because the process of welding may cause
harm to you. While doing any type of welding, it is very important to protect your eye to
prevent corneal damage. The UV rays produced at the time of welding causes great
damage to your eyes.
Therefore, it becomes obligatory to all the welders to wear a protective Welding Helmet
covering the entire face. This helmet will protect you form the sparks and the flying
materials produced from the process of welding. The welding helmet has an eyepiece of a
lens shade from which the welder can look at his weld. A heavily darkened and polarized
lens lets only a small amount of light to come in. the darkness of the lens makes it
difficult to observe anything from it besides the welding light. Thus, this auto-darkening
Welding Helmet has gained more popularity nowadays.
The Welding Helmet is designed with an aim to protect the welder form the dangers of
welding. The special darkened eye shield in the helmet protects the cornea of the eyes
from being damaged. This condition is referred to as arc eye. The eye-protection attribute
of the Welding Helmet prevents the retinal damage of the eyes that may cause great harm
to the eyes.
The auto-darkening helmet works exactly according to its name. The lens of the helmet
darkens automatically as the light form the welding begins to flash. Without the auto-
darkening feature, the lens shade would have been completely black, thus making it
impossible to see in front of you without raising the helmet.
Welding Helmet also has light sensors. These sensors indicate when to darken the lens
shade of the helmet. The light sensor is featured on the outside of the mask that is very
useful to protect some conditions like arc flash, or any other unexpected eye exposure to
the welding arc.
There are two types of Welding Helmets available in the market. These include the solar
powered Welding Helmet and the battery powered Welding Helmet. No doubt, the
functioning of both these helmets are similar and of good quality only with a minute
difference. The difference lies in the fact that the solar powered Welding Helmet has
some advantages over the battery powered Welding Helmet.
There is no on-off switch present on the solar powered helmet, hence no need to worry
about leaving the mask turned off accidentally. It can be charged naturally using the solar
energy, thus does not require battery chargers.
