If I keep the burning tip covered by the copper shield (with respect to eye location) on the gun tip how much trouble am I asking for?

This was for a crack in a muffler pipe where I build the weld to bridge for a crappy old car.

I am not a welder but I can throw molten metal on things.

Is this an absolute no-no?

I just did it and I don't have spots in my eyes but that don't make it ok.
