I was also told to start real hot to get the puddle going because aluminum dissipates heat so fast, once you get that puddle then you can back off.
TIG welding aluminum.
As I understand it TIG welding aluminum is not like steel in that the puddle you get is different. for the life of me I could not remember what "different" meant.
any tips or hints you guys can throw my way??
I found with the SS tubing Im welding, if I go over the area with a real light peddle & warm up the area, B4 I put heat into it, it wants to weld better. I just strike an arc, back off to where it will just keep the arc going & then run it back & forth over about 1 1/2" & heat it up some. then go back to the starting point, put a little more heat into it & it puddles up nice & I can just run right through that 1 1/2" area.
thanks folks
