Welding caps are an important part of personal protective equipment. As a person engaged in the process of welding, it will not only be helpful to wear this helmet when you are involved in the welding, but it can also be worn if you are around other people who are welding so the head will be protected from flying sparks.

The size of the welding cap is determined by the amount of protection it provides. There are three common types of welding caps: full-face, half-face, and open-face. Each type has different features that make it better suited for certain types of welding work.

Full-face welding caps are the most popular type because they offer the most protection. They cover the whole of the wearer’s head except for a small opening in the front for breathing.

Half-face welding caps cover only the front part of the head, and open-face welding caps leave the entire head exposed.

All three types of welding caps come in different sizes to fit different heads. The size of a welding cap is measured in millimeters (mm).
