would this be a good idea?
using a regular welding hood, and low presure, medium volume regulated compressed shop air.
I am thinking a thin flexible tube attached (velcro) to a welding hood to a small plastic box with a bunch of holes, supplying fresh air under the welding hood.
my only concern is the compressed air coming from a shop compressor, is it safe ? the compressor is located out side the shop , so it gets fresh air.
any thoughts
