Electric welding glass goggles Welding machine
1. Eye protection: double filter to avoid harmful ultraviolet and
infrared radiation produced by the arc, as well as damage caused by
welding strong light to the eyes, and prevent the occurrence of
electro-optical ophthalmia. 2. Facial protection: effectively
prevent the damage caused to the face by splashing objects and
harmful bodies in the operation, and reduce the occurrence of skin
burns. 3. Respiratory protection: air flow guidance can effectively
reduce the harmful gases and dust released by welding to the body
and prevent the occurrence of pneumoconiosis occupational diseases.
Polymer material molding, high strength, no light leakage is more
suitable for today's trend, complete varieties can adapt to a
variety of working environment needs. Solar light control welding
mask, before the arc can clearly see the welding parts, arc
automatically dimmed at the moment. The light-controlled welding
mask is a new welding mask which uses light detection technology
and liquid crystal technology. The principle is that the internal
photoelectric sensing circuit detects the light generated during
welding (mainly infrared or ultraviolet), amplifies it, triggers
the control circuit of the liquid crystal, and applies the
corresponding driving signal to the liquid crystal of the mask
(transmitted TN liquid crystal) according to the preset light
transmittance. Liquid crystal acting as light valve will change its
light transmittance. The welding will be filtered out to produce
infrared and ultraviolet radiation harmful to the human eye. At the
same time, the bright light is reduced to a low light that the
human eye can withstand. Compared with the traditional welding
mask, it not only protects the health of the operator, but also can
clearly observe the whole process of welding. It is an ideal
replacement for traditional welding masks. The dimming range can be
adjusted between 9# and 13# Light controlled welding mask is a new
type of welding mask which uses light detection technology and
liquid crystal technology. The corresponding English translation is
Auto Darkening Welding Helmet. The principle is that the light
generated by welding (mainly infrared or ultraviolet) is detected
by the internal photoelectric sensing circuit in Auto Darkening
Welding Helmet, and the control circuit of the liquid crystal is
triggered by amplification. And according to the preset light
transmittance, the corresponding driving signal is applied to the
liquid crystal (transmitted TN liquid crystal) of the mask. The
liquid crystal acts as a light valve and changes its light
transmittance. Infrared and ultraviolet rays that are harmful to
the human eye are filtered out. At the same time, the bright light
is reduced to a low light that the human eye can withstand. The
wide field of view carbon mask is a new welding mask developed by
Kimberly-Clark using the latest international technology and
combining the advantages of the light-controlled welding mask. In
addition to its excellent performance in basic protection, it can
be equipped with a welded air supply system to provide higher
respiratory protection and work in complex environments. Standard
The quality of welding mask shall comply with the provisions of
GB3609.1-94. 1. Mask size shall comply with relevant regulations.
2. Weight and thickness Headband mask (without filter and
protection) below 560g, handheld under 500g. The mask material
thickness is 1.5 mm(0.2 mm). 3. Structural requirements: (1) The
observation window, filter, protection plate and size should be
consistent, there should be a good fixed device, can not leak
radiation light from the gap. (2) Rivets and other components
should be firm, without loosening and falling off. Metal parts do
not come into contact with the human face. (3) It is convenient to
hang the glasses on the front and lift them under. 4. Mask
material: must be made of non-conductive material. After the test,
the burning speed should be less than 760mm/min, the metal parts
are soaked in 10% salt solution for 15 minutes, and the surface
liquid is dried at room temperature for 24 hours without wiping,
and then washed with warm water. The observation surface should not
change to qualify. 5. Optical properties and strength requirements
of the filter and protection are the same as those of welding
goggles
