Re: Welding fumes from 2 car garage

Not a professional but a hobby weldor. Are you wearing any PPE for your lungs? How are you doing? You are a couple feet away, if you are doing ok, someone several walls and 50' away is going to be fine as well.

As long as you have cleaned the metal of all paint, primer, undercoat, zinc coating, etc., you should be fine. Clean steel to clean steel rarely causes problems. It is the paint and other things burning off that cause the problems.

Keep the garage door open or at least part open with a well positioned fan to clear out the smoke to further mitigate any problem.

I have had more issues with the dust created by prep grinding then actual welding.

Don't use any automotive cleaning chemicals to prep your metals. Those exposed to heat CAN create deadly fumes. Brake cleaner is particularly nasty.
