Well, today I worked on a double gate for my daughter.
I changed to .023 wire in my Lincoln 175SP+. I liked it for the joints of the .065 tubing. Then I had to weld some 1/4" steel scrolls and decorations. I could hardly get the .023 to stick, so went back to the .030 for the thicker stuff. I think I will use the .023 for .065, and the .030-.035 for thicker stuff from now on.
