Tig Welding Aluminum
If someone is good at tig welding aluminum need some tips:
Tig welding some mounting brackets to my aluminum radiator, welder set on ac, remotes on, high frequency switch down, amps 90, ac balance set at 3, 1/8 in pure tungsten (green tip) with balled end, cleaned everything real good and used a clean stainless brush. My question how to get those nice tight uniform welds ( be sides practice.) Welding 1 in aluminum angle to side panels fortunately most is hidden, nothing bad just wide welds not to pretty but they'll hold. Does having the tungsten in or out of nozzle have any effect? Any tips I would appreciate at least to go back and practice.
