Hi all, Right i'm doing ally welding at college and am having a few issues with my horizontal but weld.
I cracked the lap joint straight away but this is defeating me.
Here is a couple of pics of one of the welds.
As you can see by the photo there is a white line running through the root, Don't know what this is or why its there.
I'm using a miller tig on a foot pedal.
5mm ally, approx 120amps 50% balance and 110 on the frequency.
