First tip: we call them “hoods”. As in “drop the hood and get to welding”

A welding mask to me is one of those handheld jobbies my instructor used to use back in welding school. Think clipboard on a stick with a very dark piece of glass over a cutout in the middle.

Old “welding hoods” are literally that. A big leather hood that goes over your whole head with a little fixture to hold the welding lens over your face like snow goggles. They still make this style today for real heavy welding applications
