I never weld 1/2", was just using the thicker aluminium to see if it too would give the bubbles.
It does this on 3mm 1/8" thick aluminium too. Is that just what happens to aluminium if you heat it up and do not use filler. I would love to see someone else do a similar test.
Also, tungsten so. I have always used 2% lanthanated. Boss went to the store to get supplies, I said we needed more tungsten so, gave him the old pack and off he went. Came back and the store did not know what they were and do not sell lanthanated. So he ended up with the white tip Ceriated.
What I did notice was the weld beads were considerably shinier and cleaner with ceriated.
