One of the things you may think about while welding, is possible electrocution. Yes, that is a possibility, or at least a moderate shock may be experienced if safety practices aren’t followed, but that is something we all know. But did you know that if you own a MIG or TIG welder, you could suffocate, especially if welding in a tight shop or closed garage. Yes, there are dangerous gases in the air, which could eventually cause cancer, but this is not the immediate concern with welding.
