I am just wondering. What wall thickness are you welding? When I pour the heat to it, my thinner walls melt away. (0.35) I assume that is pretty thin. I am almost always holding my torch on the side completely. I know that is a choice that I am making as a builder and quite frankly it gives me an advantage. However, it may be a sacrifice in the looks of my welds.I think a smaller rod and more heat will help get you a more fluid puddle, wash the toe of the weld into the tube a little more smoothly, and smooth out the ripples. Those are the things I focus on.
