inlet manifold looks ok now its been tarted up

my mate tom could never get the hang of ali he always said to me you dont need to be a good welder as long as you are good at grinding things lol.
i have finally managed to get the nack of ali but it took me a good year and about 3 big bottles of argon at £50 a pop. i found that a little bit of high frequency pulse helps when doing thick stuff to thin. will have a look at what the numbers on my welder say for the freq settings that i use for that sort of stuff (i just remember the positions not what it says on the switches lol).
Also i found that using Ceriated tungstens made life easier on ali, they can also be used on steel so double bonus.
