aluminum tig welding
(OP)
it has been a while, but i need someone to check to see i this is rght. for welding aluminum, the polarity is electrode pos. 100% pure tungston, and 100% argon. and adjust the heat to suit the job. and i am using 4043 filler rod. let me know thanx





RE: aluminum tig welding
Argon is the correct gas to use, as far as 4043 filler rod, it depends on the material you're welding. If I had to suggest a rod for 'general' purpose, that'd be the one I'd pick.

RE: aluminum tig welding
use an argon/helium mix shielding gas-generates a hotter arc and if you have adjustable wave shapes you can opt for better cleaning and less penetration or vice versa.
www.lincolnelectric.com have some great tips on their site.
Hope u get good results-TWWeld.
