I received a new spoolmate 100 and started playing with it. I can lay down a good bead with spray transfer on the flat parts of 3/4" 1/16" aluminum. When it comes to welding joint sections, it looks like i am trying to lay worm droppings. I go back to the flat area of the tubing and works just fine. Anyone have any suggestions? I am using a multimatic 200 with the spoolmate 100.
