There is provided a welding helmet () comprising a face protection member () moveable between a lowered position in which the face protection member () covers a wearer's face, and an upraised position, in which the face protection member () uncovers the wearer's face, a headband suspension system () for fixing the face protection member () to a wearer's head, a protective cap () comprising a flexible outer layer () and at least one compressible inner liner ().

Welding helmet

A welding helmet () has a protective shield () and a first swivel mechanism () that pivotally connects the protective shield with a head suspension system () for swiveling about a swivel axis. The first swivel mechanism enables the protective shield and the head suspension system to be swiveled between a lowered position, in which the protective shield covers a wearer's face, and an upraised position, in which the protective shield uncovers the wearer's face. The first swivel mechanism () has a recess () and a retainer () for engaging with the recess. The retainer and the recess are arranged to engage with each other in the upraised position, and to remain disengaged in the lowered position and between the lowered position and the upraised position.

An elongated guide that is removably attachable to a hardhat and a visor that is removably mountable to the elongated guide.
