Welding process involves the use if materials and components that are considered unsafe. Protective materials are therefore essential during the process. Every welder requires a welding helmet to protect against the heat, light, or gas given off during the welding process. As you can learn from Welding Wolf, a welding helmet is a personal protective gear that protects the face, neck, and eyes of a welder. It is advisable that you use a helmet together with safety goggles or other recommended glasses.
Every brand of helmet comes with different component quality. Before you make the final decision to buy a particular type, you should check the varying features and determine how they would affect your welding activity. Most welding helmets come with the following basic components:
The shell of a helmet
Most helmets for starters are made from nylon, which is a lighter material than fiberglass. It is also highly durable. For professional welding, the shell is often made from Amodel or Noryl, which are higher quality materials than nylon. These materials are costlier but they last nearly three times longer than nylon.
When it comes to choosing the lens of a helmet, you have various options to explore. The one you choose depends on the type of welding you perform. For example, there are fixed or passive lenses, which come with a permanent shade to prevent you from seeing the welding area. You can see the area only if you have a live welding arc. Passive lenses use infrared and ultraviolet-coated glass, which has a permanent shade of not less than 10. While this is an older version, many welders still find it helpful.
Auto darkening lens
This type of the lens can expand the shade to accommodate more intense light. It is important especially for the welders who have their helmets on throughout the entire welding process. The auto darkening glasses are often expensive and are available in fixed or different shades.
Welding helmets come with the various filter or viewing sizes. Traditionally, they would range from six to nine square inches. However, today it is possible to find a helmet with a viewing size as large as 24 square inches.
Suspension and Headgear
A standard welding helmet comes with a ratchet suspension, which is adjustable according to the head size of the welder. With a knob at the back of the helmet, it is easy to adjust it by just twisting the knob in a clockwise or reverse direction. This feature enables you to adjust your helmet without having to remove it. Helmets also have foam padding, especially on the forehead for comfort.
Overall, welding helmets are available in the market from reliable suppliers and online merchants.
