I started welding at an early age. In the beginning I had no instruction and had to learn on my own...
Oh, I almost forgot what I wanted to say. I stopped by my local welding supply shop for some gas and wire and they had the Miller factory guy there demonstrating their new MillerMatic 350P machine. What was really bad was the shop owner asked me if I wanted to give it a try. Don't laugh, but in all the welding I've done, I've never done any spray transfer welding; this was my first attempt. Holy cow! So THAT is how they get those beautiful robot welds you see on heavy loader arms and such!! Wow! I welded two pieces of 1/2" plate together and I've never seen such a smooth and consistent weld. Heck, I was having so much fun I welded the entire 12" pieces together in one shot.
Then came the killer part. Usually when I've seen those 'really pretty' welds, they are cold and not any good. The Miller guy sliced my weld in half and I had at least 1/4" to 3/8" penetration. Man, I was excited! Then they told me the price and I left.
