Welding Aluminum Health Risks?

[SnapB75]

I was wondering are their any health risks involved in welding aluminum? I have been welding aluminum for the past six months. I am using 100% argon when welding and the processes I am using are GMAW-P / GTAW-P.

I am doing a lot of grinding and buffing also. I know aluminum can be harmful inside the human body. So I try to use my dusk mask as much as possible. I am in a shop and there is decent air flow through the building. If it is a windy day we keep the doors down though.

I just didn’t know if there are any harmful gases that I could breathe in while welding aluminum. Could argon be harmful at all?

Thanks!
