Yeah, shielding gas. It's 75% argon, 25% CO2. The gas is inert, it is a)not harmful, and b) is only discharged near the tip, to provide an inert atmosphere for the weld so it doesn't oxidize.
If you left the bottle open, the trigger depressed in a closed environment, and the room was very small, I suppose it is possible a child could suffocate.
What you probably heard is about the fumes released from welding, which occurs no matter what welder or system you use. And a lot of that is dependent on how clean the metal is. Welding galvanized for example is very bad for you. If you had to do it, you should go outside, grind the zinc or whatever it is off, and hold your breath while welding.

Agreed on the welding class. I did that and would like to take more classes.

I've been working on tig welding lately. Requires much more patience.
For such a limited amount of stuff to do with a welder, I think the class is the best bet for MercFan to just get his hands on one and do his projects without spending too much money.
