Looking for some opinions here. I have a lot of experience welding aluminum and do it frequently. Recently, I was doing some welding on an aluminum trailer. I was welding 1/4" aluminum tube to 1/4" aluminum angle. My problem was in the overhead position the results were disastrous. Welding flat, as usual, was not a problem and produced great results.
My question is, is there an operator error here that I am not getting in doing overhead aluminum MIG?
I have a Lincoln 350MP and Prince XL spool gun with 3/64" 5356. I don't recall the settings I used but I used the same settings I welded in the flat position.
Any comments or suggestions would be appreciated.
