I've never met a MIG welder who smells good 
Some air circulation is a good thing. Melting metal creates metal fumes to some degree. These are large surface area particles of metal (think microscopic snowflakes) and you don't want that to build up. When welding in my garage I leave the door closed and then open it up when done (usually 10-15 min closed, then setting up the next stuff with door open). Plus I've started wearing a respirator a lot more when welding.
