    We use "lab grade" everything. For DCSP aluminum we use Helium. Cleaning the metal before welding is critical. We acid etch to remove anodize or alodine coatings, then scrape and alcohol wipe. Welding must be done within 72 hours or the surfaces must be recleaned.

      Many thanks .....all valuable input

      these are areas that can't be "too" clearified .


      like DCSP == DCEN & DCRP ==DCEN or is it the Other way around

      Prowess , did his stuff look like this
      My teachers build-up work


      Thanks again fellas

        Vice:
        Yep, close.
        My instructor's style had his "stacked dimes" a tad closer together, more like you had knocked a roll of dimes on their side.......but everyone has their own signature .
        I hope I can find a coupon with his work.
        I may have trashed it.

        Thanks for the post!

          you can take your non sharpened pure tungsten on dc+ on stainless steel and give it some pedal and you will see the point ball, just make sure you keeep the tungsten perpendicular to the metal or the ball will be lopsided. that is how i do it.
          Life is what you make it.

            Just for clarification, how do you take a "non sharpened" tungsten and then see the "point ball"?

              try it, i was showed how to do it that way by a guy who has been welding for the last 30 years and it works. it just forms a ball when you strike the arc and hold it for a second or two, you can see it go from a flat edge to balled.

                To clear up the DC-/DC+/straight/reverse nomenclature we need to remember that electrons are negatively charged. When you're in DC- (DCEN) the electrons are gathering in your tungsten and flying off towards the work, so it's like shooting a gun straight at your work. When you're in DC+ (DCEP) the electrons are gathering in the work, and flying out at your tungsten, so they're flowing in reverse. where the electrons are slamming into is where the heat goes.
