Hey everyone long time no talk I have been busy with school and problems with the ex that have just been ended. School has been great I finally got to try Aluminum and turns out I'm pretty good at it I figure thats the direction going. I feel so much more knowageable about welding now, I may be able to help out more around the message board I hope everyones in good health and still welding strong I just needed to ask about black spots in my aluminum weld I had a good gas flow 30PSI I do believe that machine works wierd most people were only using not even 25 is there anything I can be doing to stop this I made sure my electrode wasnt contaminated what else could it be? Oh ya I did wire brush it just to make sure thats clear.

Black spote is contamination. It could be from the substrate or the brush you used or the tungsten.....
Black is contamination thats come to surface.
