Welding T joints on 1/4 flat stock (just playing around). I have notice soot on the weld surface. I have cleaned the material that I'm welding with a wire brush, but I still get a great deal of soot on the weld surface. The weld appearance looks good though. Any help on what I doing wrong would be greatfully accepted.
Can to much gas cause this problem too. I checked the gas and it was on but way to high??? made the change and it still still leaves a soot residue on the weld. Do you think the metal has somekind of material on it that is causing the residue. I started welding on another piece of scrap and the weld appearance was good again. All I can determine is the metal I was using had somekind of flim on it or the like.....
