A welding helmet is a headgear worn during welding operations to protect the neck and the face of the person doing the welding. Some of the welding operations that require a welding helmet include arc welding, shielding metal arc welding, gas tungsten arc welding, and gas metal arc welding.

They also prevent health risks such as inflammation of the cornea, arc eye, and retina burns. Welding without proper knowledge and safety precautions can be very dangerous.
This is because of the fact that most welding processes involve an arc flame which increases the risk of facial and flesh burns. Exposure to ultraviolet emissions released during multiple arc welding processes result in corneal inflammation.
Welding helmets enable you to do welding work safely and effectively as it reduces the risk of injury. When looking for a welding helmet, it is good that you look for one with all necessary security features. Doing this will help you find a helmet that provides sufficient protection to prevent or reduce risks of injury.
Older models of these helmets were worn during most welding operations. Traditionally, the welder would work with the helmet in an upward position and pay close attention to his job. The welder would have to nod his head during the welding process for the welding helmet to fall into place and provide protection.
This is due to the fact that the older models were harder to see through while welding. However, newer models have easy viewing liquid crystal display screens that adjust automatically to differential light meaning that they can be worn at all times.
Before using a welding helmet, ensure that you check if there are any cracks. Cracks can reduce the protection a helmet offers hence reducing protection from ultraviolet and infrared rays. To remain protected at all times, look for a quality welding helmet that will protect you for a long period of time without having to be repaired or replaced.
