Even a brief exposure to arc radiation may damage your eyes, causing symptoms of temporary blindness from burning. Repeated contact may cause permanent injury. When welding or being exposed to a welding arc, always wear appropriate welding helmets and gloves.
Here is the content list:
What is the purpose of using welding helmet and gloves?
What are the components of a welding helmet?
Which welding helmet and gloves are more suitable?
The welding arc generates strong light and radiation, which may cause eye injuries. Hot molten slag and other metal debris can also cause eye damage. These debris will fly away from the weld during cooling, chipping or grinding.
Wear welding helmets and gloves equipped with a filter mask suitable for the type of welding you are performing to protect your eyes from welding light. If you do not wear welding helmets and gloves, always wear welding helmets with side shields or goggles when shaving or polishing the workpiece.
The hand shield or helmet protects the eyes by using the following components:
① Helmet shell-must be opaque, and resistant to impact, heat and electricity.
② The outer cover made of polycarbonate plastic prevents radiation, impact and scratches.
③ A filter made of glass with filler to reduce the amount of light passing through the eye. The filters have 2 to 14 different shade numbers. The higher the number, the darker the filter and the less light passing through the lens.
④ The transparent plastic fixed lens prevents any fragments of the filter from entering the eyes.
⑤ The gasket made of insulating material between the goggles and the filter protects the lens from sudden thermal changes and prevents it from breaking. In some models, insulation is provided by rack mounts instead of separate gaskets.
If you are using a standard fixed hood helmet, choose a welding helmets with a lens hood suitable for your welding application. RF provides guidelines for selecting the correct lens based on welding standards. If your welding parameters and materials have not changed, then fixed shadow lenses may be suitable for you. However, if you want to switch processes, materials or parameters, an welding helmets may be your best solution.
CSA Standard Z94.3-15 "Eye and Face Protector" divides various types of eye protectors into several categories. Each category is designed for specific purposes. Eye and face protectors should have unique markings to identify the manufacture Manufacturers and their manufacturers.
The classification of protectors commonly used in welding operations is as follows:
Category 2C-Direct/non-ventilated goggles with non-ionizing radiation protection
Level 3 and 4-welding helmets and hand shield
Class 6B-face shield for non-ionizing radiation protection
Category 7B-Masks for non-ionizing radiation protection
The following operations require the use of welding helmets for comprehensive protection:
Plasma arc cutting, gouging or welding, and air carbon arc cutting.
For gas cutting, welding or brazing, the intensity of light is much less than that of arc welding helmets, cutting or gouging. A lighter shadow filter can be used in place of goggles and goggles. We also provide Adjustable Hinge, Barrel Hinge, just follow us now!
