I have some .035 AL wire and a full tank of Argon gas.
I am keen to the fact that AL needs to be squeaky clean for good welds.
We will be welding AL from 1/8" to 1/4" in thickness.
I have the stock regulators / meters that came with my welder and was wondering if there is an ideal flow rate?
Is it possible to have too much gas flowing?
Is the .035 wire OK, or would I be better off with .030 considering the other equipment?
Any easy 'quickie' ways to clean the metal immediately before welding it up?
All hints, tricks, and ideas will be appreciated.
