It looked so nice with the corner in place, did I really want to try and weld it and ruin the corner or at best fill it full of holes? Well, I took a deep breath and tried my first tack! Lo and behold, it was a perfect little circle uniting both pieces. So I tried again allowing the metal to cool between tacks. Must have made over a hundred tacks burned through about three times but these were easy to fill with the copper backing. The right corner is about 1/2 welded in and looks far better than I ever thought it would. I used the lowest voltage and wire speed and it seems like I always do a better weld if I align myself with the weld so that I can see the wire melting. It works best if I put my eye level low so that I can see the wire fusing the two metals, kinda like putting your head on a railroad track and watching the engine (wire) fuse the metal. Well I was so happy with this result today that I had to tell someone. So if I can do it GMCdp you can do it. Good luck.
