problem i had was with heat....once it was hot - it was fine! do i need to use a blow torch and heat it up before hand?
You can heat it up with the tig torch. I like doing that on cast and other "impure" aluminium and let the cleaning action draw out the crap and open up possible porosity. Do some brushing with a stainless brush before it gets cold and it welds easier.
