There are actually full face shields that are designed to have the
narrow window that the goggles use. These are the shields you often
see guys wearing who are doing TIG and MIG welding, as well as stick
welding. The reason for the full face protection is because there is
often a lot of spatter from the welding process when using MIG and you
definately don't want those molten droplets hitting your face.
The lense in these shields is often so dark that you literally cannot
see your work with the shield down, so you get yourself arranged with
the shield up, and configured so that it will drop down over your face
with a nod. Then you get set to weld, hold you hands where they need
to be, nod your head and begin.
I removed the dark lense from the shield and put in the Tinman's lense.
He offers one lense that fits into this type of shield. I can flip it up
to light the torch and position the work. I flip it down for the actual
welding. It works for me but I do not do high production type welding.

The real reason for the dark and opaque face shields for TIG/MIG welding
is that any electro-arc welding generates lots of UV, which can cause
severe "sunburn" and skin cancer. Be sure to cover up when using any
electro-arc welder!
