Auto-darkening Welding Helmet

Auto darkening welding helmet is designed to
protect the eyes and faces of Welders from spark,
spatter and harmful infrared light, ultra-violet
light radiation under normal welding conditions.
In addition to protecting to the eyes, the helmet
protects the face from hot metal sparks generated
by the arc and from UV (Ultra-Violet) & IR
Infra-Red damage.
Auto-darkening filter fitted in it automatically
changes from light state to dark state when the
welding arc is struck and returns to the light state
when welding is stopped.
Correct shade number needs to be selected as per
the welding application process.
The shade number can be set manually between
DIN9-DIN13 by referring to the shade guide
table to determine the proper shade number for
application. Shade number can be selected by turning the knob. The shade goes darker
from 9 to 13 gradually by turning knob.
Before welding, the sensitivity shall be correctly set by turning knob to the critical point
between bright and dark.
This helmet is most commonly used with arc welding processes such as shielded metal
arc welding, gas tungsten arc welding and gas metal arc welding.
Auto-darkening Welding helmets can also prevent retina burns, which can lead to a loss
of vision. It is caused by unprotected exposure to the highly-concentrated ultraviolet and
infrared rays emitted by the welding arc. Ultraviolet emissions from the welding arc can
also damage uncovered skin, causing a sunburn-like condition in a relatively short period
of welding.
The Ultra-Violet Infra-Red protection level is up to Shade DIN16 at all the times; it
makes welders feel comfortable during welding process.
