You are welding on the construction site and the work is rarely (actually, almost never) on a bench with ventilation. The welds must be made at working surface level, in tight spaces and in body positions that are hot and cause you to sweat.
Using a supplied air welding helmet means you might be constrained by the air hose and all the potential hazards it raises (i.e., tripping, entanglement and fatigue). Wearing a heavy backpack system means sometimes you cannot even get into the tight spaces you need to be in.
So, you are hot, tired, you may be breathing in welding fumes, and getting frustrated!
