  • Marking utensils that won't contaminate

    I'm thinking about doing one of those artsy pictures on a piece of aluminum. What can I use to draw out a design that I can weld over without contaminating my tungsten?

    A scribe. Second to that small punch marks or a thin line sharpie marker, but it's mark is possibly lost in the cleaning action of the arc.

      A scribe worked pretty well. I should have done a little more for distortion control though since it's was 15ga. Oops... Haha
